Computer diagnostics of errors in Chevrolet Cruze, codes and decoding

When strange numbers or symbols appear on the Chevrolet Cruze instrument panel, this means an error due to a car malfunction, which is important to be able to decipher, reset and correct the condition of your vehicle. With each new version of the Chevrolet Cruze it becomes more and more difficult to read the codes, because... their number increases significantly. But let's look at how to behave in a situation where an error appears on the panel, how to clear the code yourself, when computer diagnostics of a car at a service station cannot be avoided, what PC programs will help you with self-diagnosis and a complete list of codes for the 2014 Chevrolet Cruze.

What to do when the main error messages come on

Cheap solution, my problem

I didn’t specifically combine them with the first four; I want to dwell on my problem in more detail. One more warning - before you get into your brains and electronics, let’s remove the battery terminals!

In general, my diagnostician was “from God,” as they say in Chevrolet and Opel, “he ate the dog,” he even worked for the officials for a year, but then he was laid off (GM left Russia). He has a professional scanner, costing 160,000 “our wooden ones”, and he updates the firmware on it every year (about another $300 - $400) - the balalaika is not cheap. Here is a photo.

But as he says, all the latest changes and information on new car models appear immediately (not only GM, all cars from our TAZOVs to Infinity). Not one ELM 327 (from China) has such information, and certainly not! Who will “cover” the annual firmware? That's why many Chinese scanners have errors - CAN'T READ!

Diagnostics - he connected his “miracle device” and it showed that it was not a choke! Wow, a stone just fell from my soul, it revealed that it was a pedal! To hell with it, I’ll buy a new one for only 3,000 rubles, and replace it myself in a couple of minutes, unscrew one bolt, remove it and connect the cable.

However, the diagnostician told me - let's try to restore this one, if the error goes away then the pedal will be 100%, and then you will decide whether to buy a new one or drive on this one for a while. Okay, I agreed. But first he says - I’ll measure all the circuits - with a multimeter, I didn’t delve further, but it turned out that the pedal does not give any breaks! Unclear! It turns out she's whole?!

He tells me this - he recently came to see me in an Astra, code 84 + ESP was also on, in the end the contact on the ECU oxidized, they cleaned it, and everything worked like clockwork. Let's take a look at you. The 6 Volt load comes from there.

As a result, they oxidized to “green oxide”, in my opinion, from 42 to 46 contacts. When they took it all apart, it was a pity that there were no photos left. They cleaned it, put it back in place, and lo and behold, code 84 - 89 disappeared, the ABS went out, the car began to breathe deeply! Damn, there’s cold and heat and condensation under the hood in the fall. Looks like they got eaten up.

In the end, I didn't have to buy anything! The cost of repairs + diagnostics is 1500 rubles - SATISFIED AS AN ELEPHANT! The master noticed that the voltage at the ECU contacts is only about 3 - 5 Volts (there are a lot of them), therefore - YOU SHOULD NOT APPLY ANY LIQUIDS TO IMPROVE CONTACTS, such as terminal protection, etc. This way you can sag the voltage and simply burn out the ECU! You just need cleaning, it is advisable not to damage the protective coating of the contact (wipe with alcohol - carefully), then blow everything off with compressed air.

The moral of this story is that, after reading on the forum, I almost removed the throttle and disassembled it! Although it wasn’t worth doing this (specifically on my AVEO)!

GUYS FIRST, LET'S GO TO A DIAGNOSIS - A INTELLIGENT DIAGNOSIS ! And then we’ll self-medicate (otherwise you might end up doing a lot of things). And yes, again, from the first steps, after adding antifreeze (if the level is gone), look at the contacts on the ECU, clean them - perhaps the problem will be solved. We rode with the master for about 5 - 10 kilometers, no mistakes!

This is the story, I hope it helped! I tried to put it on the shelves as much as possible, there is information on the Internet on forums, but it varies everywhere, there is no common denominator - maybe this, or maybe that! Check all the devices that I described to you - the error will go away in 95% of cases.

Fuel system

There are several weak points in the fuel system that can make the power plant unable to start. The reasons for their failure are most often associated with the use of low-grade fuel. Typical fuel system problems are shown in the table below.

To eliminate a malfunction in the fuel system, it is recommended to first check the condition of the fuel injectors. If diagnostics show a violation of the spray pattern, then ultrasonic cleaning is recommended.

It is also necessary to check the condition of the fuel pump and fuel filter. The Chevrolet Cruze does not have a special access hatch under the rear seats, so the gas tank will need to be removed. During this event, you can assess the condition of its internal walls and visually check the quality of the filled fuel.

Before writing why the Chevrolet Cruze won’t start, I thought about describing serious problems. However, after reading the Chevrolet Cruze Club forum, I realized that people do not know the most basic things, and car owners are faced with problems that it is indecent for a more or less experienced driver to even talk about. So let's begin.

Why do you need a damper with a sensor and how does it work?

In injection cars, the air and fuel supply is controlled using an electronic unit, into which information from numerous sensors and systems flows. Thus, the angle of the damper is controlled by its position sensor. The choice of the deflection angle is necessary for the formation of an optimal air-fuel mixture and normal engine operation (without jerking and loss of power). Throttle valves on older cars were driven by a cable that was connected to the accelerator pedal. Modern dampers are deflected using a drive motor.

Please note that some remote sensing devices have not one, but two sensors. Accordingly, they will have more possible errors. There are two types of sensors - contact, they are also called potentiometers or film-resistive and non-contact, another definition is magnetoresistive.

Regardless of the type of TPS, they perform the same function - they transmit information about the damper deflection angle to the electronic control unit. In practice, this is realized by converting the damper deflection angle into a constant voltage value, which is a signal to the ECU. When the throttle is completely closed (idling), the voltage is at least 0.7 Volts (may vary for different cars), and when fully open - 4 Volts (may also differ). The sensors have three terminals - positive (connected to the car battery), negative (connected to ground) and signal, through which variable voltage is transmitted to the computer.

Chevrolet Niva error codes: decoding and description of meanings

The popular Russian-made model is very widespread in the CIS countries due to its optimal cost and increased cross-country ability, which is critically important in the conditions of domestic operation. Motorists buy cars for off-road travel and small towns, where the quality of roads leaves much to be desired.

The disadvantages of the car include weak wiring - when the load increases to the design limit, on-board electronic systems often fail, which causes software failures. Chevy Niva error codes appear on the dashboard display or are detected using special equipment, but the common thing is that they all indicate a malfunction of a specific component.

Causes

What do error codes 84 and 89 mean on a Chevrolet Cruze? The answer to this question is simple. These numbers mean the following:

• Code 84
  – engine power reduced;
• Code 89
  – scheduled maintenance has reached its due date.

Often, simultaneously with error 84, visible problems with the motor begin; there may be several reasons for this code. Below we'll take a closer look at why they appear. Be sure to conduct a detailed diagnosis. It often reveals additional errors that can be used to determine the malfunction more accurately. Code 89

. This is perhaps one of the most harmless codes. This error occurs when it is necessary to undergo scheduled maintenance. This happens when a certain mileage is reached. Often this error can occur when the speedometer sensor malfunctions. In this case, be sure to check its condition. If everything is fine with it, visit the service. You can also replace parts that are time to replace yourself. A more detailed list of required work can be found in the official regulations published by the manufacturer.
