When previously unknown symbols and signs suddenly appear on the instrument panel, these are most likely messages from the on-board computer about problems that have arisen in one of the car’s systems. The ability to correctly decipher these messages allows you to promptly identify and get rid of problems that have arisen. With the advent of new Chevrolet models, decoding is becoming increasingly difficult, as their number increases.
For correct recognition, it is best to perform diagnostics using special equipment, or check messages on the car’s dashboard. Models have appeared in which a message is displayed instead of a code. For example, a message may appear indicating that the time for changing the engine oil is approaching, or other similar messages. To find out in more detail about the problems that have arisen, it is best to use a special scanner.
They are a small computer in which a special program is installed, with its help the machine can be independently diagnosed. There are two types of such scanners:
Error codes - decoding

How to reset Aveo errors
To remove faults, simply remove the terminals from the battery and wait 20 minutes. After this, everything returns to its place and the on-board computer restarts in the reset position.
Aveo standard error codes are a complete set of ciphers that describe the real state of the machine’s electronic systems.

What is the reason for the errors?
There are a lot of reasons, but it’s worth noting that they are not always critical, so you shouldn’t buy spare parts right away!
Guys, I want to warn you - before sounding the alarm, you must first look for an intelligent diagnostician and only then draw conclusions! After all, my problem was not at all with the throttle. But this became clear later.
Precisely a smart one with a good scanner, who understands your Chevrolet or Opel, because if you connect a cheap scanner like ELM 327, then it simply may not detect the error!
SO, what problems there may be, I’ll start with, perhaps, the most harmless one:
Probably intrigued. To be honest, the diagnostician struggled with the car for almost a day. But I found a problem.

Air supply system
A malfunctioning or clogged throttle body can cause your vehicle's check engine light to flash. In this case, in order to fix the problem, you will have to dismantle the air distribution unit and clean it.
It is worth noting that car mechanics recommend cleaning with a special liquid, but motorists can also use a regular carburetor cleaner. Also, along with the throttle, it is worth cleaning the corrugations that supply air to the unit. As practice shows, it is also often clogged.
Symptoms of malfunction
The main driver symptom of P0303 is the MIL (Malfunction Indicator Light) illumination. It is also called Check engine or simply “check light”.
They can also appear as:
- The “Check engine” warning light on the control panel will light up (the code will be stored in the ECM memory as a malfunction).
- The engine stalls or has trouble starting.
- Floating speed, as well as attempts to stall at idle.
- Jerking/misfire at idle or under load.
- Poor speed gain.
- Increased fuel consumption.
- Reduced engine power.
- Smell of fuel from the exhaust.
Malfunction P0303 is considered serious and must be corrected as soon as possible. Because prolonged driving with a misfire can cause costly damage to the engine and catalytic converters.
Chevrolet Aveo won't start
While operating a Chevrolet Aveo, a car owner may encounter an unpleasant situation when his car refuses to start.
There are many reasons for the inability to start the engine, and they all have different origins. Some breakdowns can be easily fixed, but there are also those that require a visit to a service center to fix.
Errors P0030 and P0135 in the Chevrolet Aveo T300
In the morning, after driving about two kilometers, the revs dropped, then (after 150 meters) the engine stalled. The check light came on.
I counted the mistake, there were two of them. P0030 and P0135. Scanner recommendations, check wiring, check fuse, replace sensor, ECM.
The essence of the question is this: I want to carry out the repair myself, but I can’t find a video review on my question. Help with advice or a link to a repair video. Thanks in advance.
First of all, check the sensor connector itself and whether voltage is coming to it; what checks need to be carried out for these errors are described in detail here.
P0030 - Heated Oxygen Sensor 1 Bank 1 Heater Control - Circuit malfunction. Check the connector, wires and the oxygen sensor itself (the first one from the engine).
P0135 - Heated Oxygen Sensor 1 Bank 1 Heater Control - Circuit malfunction.
The best way to test an oxygen sensor is with an oscilloscope.
Here is a diagram of the normal operation of a lambda probe
Regarding the repair of oxygen sensors: if the mileage is already well over 100 t.km, then definitely change the lambda (because they have a service life of approximately 100 t.km).
Also, I came across a person on the forums who boasted that he had removed the oxygen sensor, soaked it in a decarbonizing solution (for about a day), and that sensor started working again (personally, I doubt that such soaking will update the lambda probe, but there were no details, for example according to mileage, so anything can happen).

How to read errors
In order to read errors, you need to connect to a laptop or tablet PC, and the other end of the cable to the car via a special K-line cable. Let's look at what tools will be needed to connect the car to the computer and determine error codes:
Diagnostics and repair of the control unit.
In order to connect, you need to find a connector for the cable. It is located under the steering column. Now you need to connect the cable itself and then the USB connector. The programs considered optimal for use are: Open Diag Free, Tyranus Daewoo Scanner, ECM Diagnostics (KWP_D) and Chevrolet Explorer v1.7.
Technical description and interpretation of error P0303
The OBD II error code P0303 is a generic one that reads “Cylinder #3 misfire detected.” Set when the PCM (powertrain control module) detects a misfire in the third cylinder.
The misfire detection system uses input data that is sent to the PCM through dedicated feedback circuits. If the PCM does not receive feedback, it interprets this as a misfire.

Diagnosis and problem solving
If your car is new enough, the transmission is covered under warranty. Therefore, it is better to contact your dealer for repairs. When diagnosing yourself, follow the recommendations below.
First, visually inspect the crankshaft and camshaft sensors and their harnesses for damage. If you notice broken/deteriorated wires, repair and recheck.
Check the location of the cam and crank. Remove the cam gear and crankshaft balancer and inspect the rings for irregularities. Check that they are not loose or damaged, or cut off by the key that aligns them. If there are no problems, replace the sensor.
If the signal is normal, check that the timing chain/belt is aligned correctly. If they are displaced, it is worth checking whether the tensioner is damaged. Which could cause the chain/belt to slip a tooth or several teeth. Also make sure the belt/chain is not stretched. Then carry out repairs and double-check with a scanner for error P0016.
If you need more specific information about your vehicle, consult your factory service repair manual.

A few more words about error codes
Many owners are looking for an answer to the question of what code 24 means. This signal on the instrument panel indicates problems with the license plate lighting of the car. For such a malfunction you can be punished by a fine, so the malfunction must be eliminated. Let's look at this in more detail.
Since the license plate lights are connected to the vehicle's electrical system, you need to check the fuse in this circuit. A separate device is not installed for this circuit; usually it is a side light fuse. It is set to a current of 10 Amps
, so check this device first. However, I would like to immediately warn you that its failure does not always happen.
The wires that supply power to the backlights have too rigid insulation, so they break after frequent bending. Open the trunk and on the left side of the car, check the condition of the wiring. Usually a break is detected by touch, after which you should disconnect the white connector, eliminate the broken wire and put everything back in place.
The situation is somewhat worse when the break occurs near the connector itself. In this case, you will have to disassemble it to replace the wire in the connector terminal. But that's not all. The problem may be burnt out license plate light bulbs. In this case, you will also have to tinker, since in order to replace them, you need to disassemble the trunk panel. Only after this can faulty devices be removed and replaced.
As you can see, problems exist, but they are completely solvable, including with your own hands. Chevrolet Aveo T300 and 24 error codes are far from the only ones; there is also a fairly large list of them. Therefore, it is advisable for all owners to have it in their car for prompt response.
How to Troubleshoot or Reset Trouble Code P0303
Some suggested steps to troubleshoot and fix error code P00303:
- Use an OBD scanner to make sure there are no other errors. If they are present, it is recommended to eliminate them first.
- Inspect the looseness of the connectors on the ignition coils or any damage to the wiring. Also look for loose engine ground wires. This may cause random misfires. Tighten or correct if necessary.
- Check the condition of the spark plugs and their wires. Worn and old spark plug wires are common causes of random misfires. Replace spark plugs and wires if necessary.
- It is necessary to measure the fuel pressure. Low pressure can cause intermittent misfire in multiple cylinders. When the pressure is below specification, the engine does not receive the proper amount of fuel and begins to lean the mixture. The fuel pump or pressure regulator may be the source of low pressure.
- Make sure the fuel injectors are working properly and activating. Random misfires may be a sign of faulty or clogged fuel injectors that need to be replaced. Also check that the fuel injector wiring is not damaged and is connected correctly.
- If the ignition and fuel system pass inspection, you can perform an engine compression test and a leak test to see if there are any mechanical problems causing the misfire.

After analysis, it turned out that the resulting list of diagnostic trouble codes had been accumulated over a long period of time as a result of sensors being disconnected during repairs. To identify current errors, we reset everything in two blocks and conducted a short drive to obtain the most up-to-date list of diagnostic trouble codes in a short time. As a result, errors appeared in the engine control unit in the oxygen sensor before the catalyst, and in the ABS unit the list of errors looked the same as during the initial inspection.
Engine diagnostics
When analyzing the current engine operating parameters, it was found that at the moment when the signal from the oxygen sensor “with an error” was not involved in engine control, no obvious signs of the declared malfunction were noticed when the engine was idling. As soon as the control unit turned on the control mode based on a signal from the oxygen sensor “with an error,” the declared malfunction immediately manifested itself. The sensor malfunction has become obvious. As an additional check, so as not to make a mistake in making the correct diagnosis, the oxygen sensor was turned off. With the oxygen sensor disabled, it is impossible to enable the so-called “Close loop” mode; the essence of this mode is based on adjusting engine operating parameters based on the signal from the oxygen sensor to the catalyst. Without a sensor, the “Open Loop” mode is activated, which is not active for a long time, for example, during engine warm-up and during acceleration on fully serviceable motors, both in the mechanical part and in the control system. This test under diagnostic conditions under various loads showed the absence of the declared malfunction, while with a connected sensor “with an error,” the malfunction appeared after a short time.
ABS diagnostics
The entire list of errors for ABS appeared again after cleaning it. The list itself indicates the presence of problems in the operation of all four ABS sensors installed on the wheels, and consists of two groups “unreliable” and “low signal amplitude”. The first group of errors indicates unreliable data from the sensor; in this group there is no error for the rear left wheel sensor. The second group, “low signal amplitude,” contains errors in the sensors of all four wheels. The moment the ABS indicator turned on on the instrument panel, problems with automatic transmission gear shifting began. As practice shows, under normal vehicle operating conditions, all 4 sensors cannot fail at the same time; another argument in favor of the serviceability of the sensors and its wiring is that the control unit reports unreliability and low signal amplitude. In other words, a signal from the sensors is received by the ABS unit, but there is something wrong with it. Viewing the data that enters the ABS control unit from the sensors on the day of the initial inspection showed the following wheel speeds: rear left 160 km/h, all others 0 km/h, regardless of vehicle speed. During diagnostics the next day, the same parameters changed, rear left 0 km/h, all others corresponded to the actual speed of the car. When examining the rear wheel sensors, it turned out that the sensors have minor damage and are slightly worn by the master disk, but this does not prevent the right sensor from working properly, while when checking the left one, receive a signal both from the ABS unit using a scanner, and from the The motor tester did not work with the sensor. Swapping the rear wheel sensors confirmed that the left sensor or its wire was faulty, despite the absence of visible damage. No problems were found in the wiring harness of the left ABS sensor from the junction with the sensor to the ABS control unit. The sensor is not dismountable and cannot be repaired, while internal damage to the sensor harness in the event of a break is repaired. Before diagnosing the malfunction of the rear left ABS sensor, we agreed with the customer on cutting the cable for testing; the check showed that there were no problems in the cable. A faulty sensor, transmitting an incorrect signal from time to time, caused errors in the operation of the ABS unit with working sensors, at this time the engine control unit and automatic transmission remained without data on the vehicle speed and went into emergency mode, which does not ensure smooth and timely gear shifting, but is intended for a slow, short trip, taking all possible precautions, to the repair site.
The rear left ABS sensor is faulty and needs to be replaced. The oxygen sensor before the catalyst is faulty and needs to be replaced.
Chevrolet Aveo fault codes: decoding
Two methods of reading and diagnosing breakdowns are applicable to a car of the specified model.
The first option involves the use of built-in on-board systems. There is no need to use third-party units or dials here. A standard BC can independently install the circuit where there is a breakdown. The disadvantage of the procedure is the lack of fault details. The driver needs to find a specific part on his own.
In the second option, you will need to get a special diagnostic scanner and master it at least at a minimum level. Despite the complexity of the preparation and diagnosis itself, the procedure allows you to determine the specific unit, and even the place where the breakdown occurred.
The following is information on deciphering the main, common problems.
Error 16
Most often found on cars 2012-2013. The problem is related to the detonation module. Most likely the fault is in the sensor or its contact group.
Chevrolet Aveo: error 18
A standard “sore” for cars in the back of the T300. The problem is hidden in the knock sensor or its wiring. Detailed diagnostics of the node will help correct the situation.
Error 20
On cars in the back of the T200, the error occurs frequently. There is no such code in the standard fault table. This code is a combination of several problems at once. To find out a specific breakdown, perform a more thorough diagnosis.
Code 24 - Aveo T300
When an error appears on the dashboard, the speedometer stops working. There is a speed sensor error here. The device is installed on the gearbox and is easy to change.
Before removing a fault from the list, it must be eliminated mechanically.
27 - error
Problems have been discovered in the air conditioning system. Check the A/C compressor and clutch.
Error 84
Similar problems occur in cold weather when the driver uses low-grade fuel. The error literally means that the power plant is switched to emergency mode and all third-party equipment is turned off.
There are problems with the throttle here. The malfunction needs to be studied and eliminated in more detail.
Aveo: error 89
When such a problem occurs, the head radiator fan turns off in parallel and runs constantly. This effect periodically appears and disappears. There is an error in the coolant temperature sensor - the module has failed and is not working correctly.
This behavior raises doubts among drivers about the possibility of driving in this situation. Theoretically, nothing prohibits driving further, but in this case the load on the on-board network and fuel consumption will increase significantly.
Experienced specialists recommend not to bother with repairs and change the sensor immediately and entirely.
Error P0011
Indicates that the phase distributor is not working properly. The system needs a thorough inspection.
Error P0012
The signal from the camshaft position detection system takes too long.

Code C0561
The error is for informational purposes only. This is how the car indicates that the traction control system has been disabled. ESP.
ABS malfunction
ABS errors are scattered across the list of faults so that it is difficult to list them together.
Typically, module problems are associated with damage to sensors, wiring, or the effects of moisture.
Camshaft sensor errors
DPRV malfunctions periodically appear due to natural wear and tear of the sensor. This can happen after an unsuccessful repair.
Airbag errors
The system needs to be repaired immediately. Igniter failures are associated with damage to the squib wiring.
Catalyst errors
If there is damage to the catalytic converter system, environmental regulations force drivers to replace the worn element with a new one. At the same time, most warriors simply cut out the part and put a plug in its place.
Throttle faults
Here the repair consists of cleaning the module from dirt, carbon deposits and foreign objects that get there through the air duct system.
Engine errors
Thanks to its excellent layout, the power plant rarely gives in to the driver’s whims. Usually this is due to attachments. In this case, if the corresponding light on the device lights up, you should immediately check the car.
What is error code 89 (P0597) on Aveo T300, consequences
hoses and pipes crack;
antifreeze works in borderline mode and wears out faster; the plastic housing of the Chevrolet Aveo t300 thermostat is not very durable anyway, and at high temperatures it begins to leak literally a couple of thousand km after the error appears; well, the engine also has a hard time with temperature violations.
The electronic engine control unit controls the thermostat using pulse width modulation signals. An antifreeze heater is installed in the thermostat housing of the Chevrolet Aveo t300. It is he who regulates the flow of coolant and controls the operating temperature.
The ECU must constantly supply 12 V to the thermostat and control the heater by connecting it to engine ground. The connection is made via a semiconductor signal conditioner. It has a feedback circuit connected to a common 12V supply.
The engine control unit controls the entire device by reading the heater feedback voltage. Thanks to this scheme, the ECU easily calculates the performance of the entire thermostat and can detect both a short circuit to ground and an open circuit, which will signal the driver with a fault code. And yet, if we have a scanner or PC at hand, in addition to error P0597, we can receive accompanying error codes - P0598 and P0599.
These are clarifying codes that can be deciphered something like this:
In a word, it is clear that when code 89 or error P0597 appears on the BC display on the Aveo T300, our task is to check or get rid of the antifreeze heater, if possible.
Error P0303 Chevrolet - misfire in the third cylinder
Misfire detected in cylinder 3
Possible causes of the error in a Chevrolet car: • The ignition coil of the third cylinder is faulty • The spark plug of the third cylinder is faulty • The injector of the third cylinder is clogged or faulty • A break or short circuit in the wiring of the ignition coil of the third cylinder • A break or short circuit in the wiring of the injector of the third cylinder • Malfunction of the third cylinder injector wiring connector • Malfunction of the third cylinder ignition coil connector • Incorrect fuel pressure • Low compression in the 3rd cylinder • Intake manifold air leak
The P0303 error code means that a misfire or random misfire has been detected in the third cylinder of the Chevrolet engine. It is better to carry out diagnostics in the following sequence - check the intake tract for air leaks, the next step is to replace the spark plug in the third cylinder. If the problem cannot be solved by these two points, then it is necessary to carry out additional diagnostics, which are described in detail here.
POSSIBLE SYMPTOMS OF ERROR P0303 Chevrolet : • “CHEK ENGINE” signal is on; • Lack/loss of engine power; • The engine shakes. Uneven engine operation; • It is difficult to start the engine. Especially cold.
Chevrolet Error Description If a misfire occurs, the engine speed will fluctuate. If changes in engine speed are sufficient to change the crankshaft position (CKP) sensor signal, the engine control module (ECM) detects the P0303 Chevrolet .

Engine won't start Chevrolet Aveo T300
The crankshaft does not turn with the starter
The cause is usually a discharged battery or loose wire ends at its terminals. If the wire ends are tightened tightly and the starter does not turn, you can try to start the engine using a “donor” battery (see “Starting the engine from external power sources”).
HELPFUL HINT: If the battery is completely discharged when the vehicle has just been stopped, check the charging system (see “Battery will not charge”).
If the starter armature does not begin to rotate even though the battery is in good condition, check whether the fuse link No. 54 has burned out and whether the starter relay No. 55 is securely fastened in the mounting block of the engine compartment.
In addition, in road conditions, you can check the fastening of the “mass” wires of the battery and starter to the body. To do this, you need to remove the battery shelf (see “Removing and installing the battery mounting shelf”). To further check the starting system, you will have to call a tow truck, since the car needs to be placed on a lift or inspection ditch.
1. Having removed the crankcase protection and the front engine mudguard (see “Removing and installing mudguards and engine crankcase protection”), check the tightness of the starter contact connections.
2. Check the presence of voltage at the power contact of the starter traction relay. To do this, connect one wire of a 12-volt lamp to ground, and the second to the contact bolt. If the lamp lights up, the starter power circuit is working. Otherwise, check and restore the power circuit (see “Diagnostics of faults in on-board electrical equipment”).
3. If the wire ends are securely tightened, the power circuit is in good condition, and the starter does not work, disconnect the ground (disconnect the wire from the minus terminal of the battery) and disconnect the control wire from the traction relay (see “Removing and installing the starter”). Connect a 12-volt lamp between the control wire tip and ground. Securely insulate the tip of the power wire disconnected from the traction relay or install it in place to prevent the tip from touching metal parts of the car, then turn on the ground (connect the wire to the minus terminal of the battery). Have an assistant turn the ignition key to the “starter” position. If the lamp lights up, remove and repair the starter (see “Starter Repair”). If the lamp does not light, check and restore the starter control circuit (see “Diagnostics of on-board electrical equipment malfunctions”).
NOTE: Sometimes it happens that when you turn the ignition key, the starter turns on, its armature rotates, but the flywheel remains motionless. The reasons may be loosening of the starter to the clutch housing, damage to the teeth of the flywheel or drive gear, slipping of the freewheel of the drive, breakage of the lever, drive ring or buffer spring of the starter drive.
The crankshaft rotates, but the engine does not start
1. Open the hood and make sure there are no leaks in the connections of the engine power system. Look under the car for leaks in the fuel tank and fuel lines.
2. Remove the air filter element (see “Replacing the air filter element”), replace the filter cover and try to start the engine. If the engine starts, replace the filter element.
NOTE: Never make even short trips without an air filter element: road dust will immediately damage the engine cylinder-piston group.
3. If the engine does not start, unscrew the cap under the hood to check the fuel pressure in the fuel rail.
4. To protect against fuel splashes, take a large, absorbent rag and place it around the fitting. Using a screwdriver, carefully press the valve spool rod. If fuel sprays out of the fitting, the pressure in the power system is sufficient to start the engine. In this case, proceed to check the engine management system (see below).
WARNING: Fuel leaks in the engine compartment are a fire hazard, so before continuing work, carefully wipe off any traces of fuel and ventilate the engine compartment.
5. If the check shows that there is no required fuel pressure in the rail, turn on the ignition and listen: within a few seconds you should hear the sound of the electric fuel pump operating in the area of the fuel tank (under the rear seat).
NOTE: Keep in mind that if there is pressure in the fuel rail, the electric fuel pump will not turn on. This is not a malfunction.
6. If the fuel pump hums when the ignition is turned on, but does not create pressure in the fuel rail, a clogged fuel inlet screen or filter built into the fuel module, a faulty fuel pump or pressure regulator are to blame. For all these malfunctions, it is necessary to replace the non-separable fuel module. This can only be done when installing the car on a lift or inspection ditch (see “Removing and installing the fuel module”).
7. If the sound of the fuel pump is not heard, it is necessary to check and restore the power supply circuit of the fuel pump (see “Diagnostics of malfunctions of on-board electrical equipment”), and if it is operational, you should replace the fuel module with a burnt out or jammed pump (see “Removal and installation of the fuel module"). To do this, you will need to remove the fuel tank (see “Replacing the fuel tank and its filler pipe”). That is why such a check is impossible in road conditions. On the road, you can only check whether fuse No. 35 has blown and whether the fuel pump relay No. 34 is securely fastened in the mounting block of the engine compartment. The engine control system should be checked using special diagnostic tools (see “Irregularities in engine operation”).
If there is no diagnostic tool, under road conditions you should check the integrity of fuses No. 36,42,45,46, 47, 48, 49, 50 in the mounting block of the engine compartment.
. and reliability of fastening of relay No. 3 of the fuel injection system and ignition system in the same mounting block.
In addition, check the reliability of the connection of all engine wiring harness blocks accessible for inspection in the engine compartment, paying special attention to the engine control unit block blocks.
. ignition coil unit (see “Removing and installing the ignition coil unit”).
. crankshaft position sensor (the block is located at the rear of the engine cylinder block, behind the starter) and other sensors of the engine management system (see “Engine management system fault codes”). If the check does not reveal any violations, use a diagnostic tool (see “Irregularities in engine operation”) or contact a car service center.
USEFUL TIPS: If the engine is very worn, it will be difficult to start in the cold season, even with working power supply and engine control systems.
If during an unsuccessful start attempt the spark plugs are flooded, use the cylinder purge mode. To do this, press the accelerator pedal all the way and, holding it down, turn on the starter. In this mode, there is no fuel supply and excess gasoline is removed from the cylinders by a stream of fresh air, while the spark plugs are dried. After purging, try starting again as usual.

Resetting errors on Chevrolet
If malfunctions are found in the operation of certain systems, then the first thing to do is to correct them. If after repair the codes remain in memory and do not disappear, then you can eliminate them yourself.
There are several options for resetting errors:
- Clear codes by disconnecting the battery terminals. Open the hood and loosen the bolts on the clamps, then disconnect the alligator clips. Wait about one minute, then connect the crocodile clips into place.
- Using the on-board computer. The device has a special function for this. To delete the code, go to the “errors” section in the main menu, then press the middle key on the panel. You will hear a beep and dashes will appear on the computer display. If they exist, then the errors have been successfully removed from memory.
- Resetting can be done using the odometer button. You need to hold it down for five seconds. About 15 seconds will pass, after which the numbers will appear on the display. We wrote about errors during self-diagnosis at the beginning of the article, but if the number 0 appears on the display, then there are no problems with the operation of the sensors, engine and other systems in the car.
Chevrolet Aveo T300 and 24 error codes. Deciphering and correcting
After some time of operation, owners have questions about what Chevrolet Aveo T300 and 24 error codes are. The on-board computer installed on modern cars is designed to control the car’s systems, and also informs the driver about any problems with the car. This increases reliability and safety during operation, and also speeds up the process of detecting and eliminating faults.
Chevrolet Aveo T300 and 24 error codes warn the owner that there is a problem in the vehicle systems. Knowing and being able to decipher the error codes that are displayed on the on-board computer display, you can easily decide what to do in such a situation. In some cases, you should stop moving, in other situations you can continue, but then fix the problem.
Troubleshooting and reset
Eliminating ECU errors is quite simple. In the reading program, you need to find the desired fault and decipher it. Then, it is recommended to fix the problem that caused the error. The last step is reset. It can be found in program tools or actions.
Many car enthusiasts make a mistake when working with software, because they “reset” not the errors themselves, but the entire software, thus leaving only the car software shell. After such actions, usually, the car may not start and software adjustment of the equipment or replacement of the entire software as a whole is required. Therefore, in this case, it is recommended to contact a car service, where they will do everything correctly.
A few words about car diagnostics
When previously unknown symbols and signs suddenly appear on the instrument panel, these are most likely messages from the on-board computer about problems that have arisen in one of the car’s systems. The ability to correctly decipher these messages allows you to promptly identify and get rid of problems that have arisen. With the advent of new Chevrolet models, decoding is becoming increasingly difficult, as their number increases.
For correct recognition, it is best to perform diagnostics using special equipment, or check messages on the car’s dashboard. Models have appeared in which a message is displayed instead of a code. For example, a message may appear indicating that the time for changing the engine oil is approaching, or other similar messages. To find out in more detail about the problems that have arisen, it is best to use a special scanner.
Errors 84 and 89 on Chevrolet Cruze: what they mean and how to get rid of them
Electronic control units of modern cars have diagnostic functions, which greatly simplifies life for drivers. If the ECU sees an error in the operation of the engine and other units, the driver is notified about this by the corresponding information on the multimedia system display. The Chevrolet Cruze also performs automatic diagnostics, capable of notifying the driver of various problems. Most often, owners of this car model have to deal with errors 84 and 89. They signal corresponding problems that need to be eliminated in order for the engine to operate in standard mode again.
Chevrolet Cruze: error code 89
All owners of a Chevrolet Cruze have to deal with error code 89. This error does not indicate a failure in the system, but warns the driver that it is time to undergo scheduled maintenance. The electronic control unit informs the driver about error 89, based on the speedometer readings. The following course of action is suggested when error 89 lights up on the display:
How are the codes deciphered?
As already noted, with each new car model, the number of codes increases. It is simply impossible to talk about all possible combinations in this article, so we will focus on some of them. There are a number of errors that occur most often, and some of them occur in extremely rare cases. It is advisable for car owners to print them out and take them with them in order to decide on the course of further actions at the right time.
An example is error P0300
, which reports multiple misfires. To get rid of this problem, you need to check the entire ignition system of the car. Control sensors are located in all major vehicle systems, so any malfunctions that arise do not go unnoticed.

A few more words about error codes
Many owners are looking for an answer to the question of what code 24 means. This signal on the instrument panel indicates problems with the license plate lighting of the car. For such a malfunction you can be punished by a fine, so the malfunction must be eliminated. Let's look at this in more detail.
Since the license plate lights are connected to the vehicle's electrical system, you need to check the fuse in this circuit. A separate device is not installed for this circuit; usually it is a side light fuse. It is set to a current of 10 Amps
, so check this device first. However, I would like to immediately warn you that its failure does not always happen.
The wires that supply power to the backlights have too rigid insulation, so they break after frequent bending. Open the trunk and on the left side of the car, check the condition of the wiring. Usually a break is detected by touch, after which you should disconnect the white connector, eliminate the broken wire and put everything back in place.
The situation is somewhat worse when the break occurs near the connector itself. In this case, you will have to disassemble it to replace the wire in the connector terminal. But that's not all. The problem may be burnt out license plate light bulbs. In this case, you will also have to tinker, since in order to replace them, you need to disassemble the trunk panel. Only after this can faulty devices be removed and replaced.
As you can see, problems exist, but they are completely solvable, including with your own hands. Chevrolet Aveo T300 and 24 error codes are far from the only ones; there is also a fairly large list of them. Therefore, it is advisable for all owners to have it in their car for prompt response.
Chevrolet Aveo from the ZR fleet: the cost of a mistake
Hurray, it worked! Only children can be so sincerely happy. Well, me too. Because before that, I spent almost a year knocking on the doorsteps of dealer services in an attempt to overcome a mysterious malfunction that was tormenting the editorial Chevrolet Aveo.
Chevrolet > Aveo
Chevrolet Aveo 1.6
Manufacturer:
Avtotor, Kaliningrad
Year of issue:
2012
In “Behind the wheel” operation:
since June 2012
Mileage at the time of report:
108,000 km
Publications in ZR:
2012, № 10; 2013, № 3, 7, 11; 2015, № 2, 7; 2016, № 4, 9
It all started after replacing the camshaft phase shifter gears (ZR, 2015, No. 2). During dynamic acceleration, and sometimes even during steady motion, a warning light came on on the dashboard, informing about malfunction code 89 (high noise level, according to the knock sensor), and the engine lost power.
I went to the dealer, fortunately the warranty was not over yet. The service center specialists carried out initial diagnostics, and they confirmed that the error actually occurs due to noise in the engine. We ran the engine on obviously high-quality fuel, changed the knock sensor - it didn’t help. After a consultation, the servicemen decided: the noise occurs due to increased gaps in the piston group. You need to disassemble the engine and carefully check every detail.
The piston group turned out to be in perfect order. But it turned out that the impulse ring on the exhaust camshaft, by which the sensor determines its position, was broken. In addition, the valve springs sagged and their plates were cracked. Some replacement parts were not in stock - the car sat with the engine disassembled for three weeks awaiting delivery.
All efforts were in vain: during a test drive, the lamp came on again. Dealers took a pause to think about it, but it lasted four months. The responses to my calls were like carbon copies - we are waiting for a response from the head office. And I lost my patience.
