Lada 4×4 3D › Logbook › Extras. Niva starter relay

Hello friends! I wrote about my problem with starting the car earlier, the essence is simple: you turn the key, and in response there are only clicks. I didn’t know what it was, the car had this problem since it was purchased in November 2015. Since then, there have been no hypotheses, no matter what has not changed (explosive wires, starter retractor, switch), in addition, all the places where the minus is attached to the body have been cleaned. Nothing helped. We thought and wondered, consulted for a long time - what to do? I asked a question here, they gave me different advice, and so my friend and I decided to install an additional relay on the starter. Maybe it will help! And let me tell you, it helped! To solve the problem, we bought: a 4-pin 30A relay, “mothers, fathers”, 1.5 wire (taken with a reserve), heat shrink. We prepared and assembled everything according to the diagram, all that remains is installation.

Full size did everything as advised

Full size when all the wires have been prepared, all that remains is to connect according to the diagram

Full size opened the main circuit, connected it to the relay, again according to the diagram

Full size of the relay itself secured together with the switch

The full size was made according to this scheme - everything works! It took about 15 minutes to prepare the wires, then we connect according to the diagram and try - everything works! Starts with half a turn! After installing additional relay no matter how much I tried to turn the ignition key, the car always responded as it should! Problem solved, now it's just history!

Where are the blocks and relays located in Niva 21214 and 21213

The main power supply in these models is located under the lower edge of the instrument panel protection. Additional fuses in Niva 21214 for the injector are located to the left. This block is responsible for controlling fuel injection. There are also relays for monitoring the operation of the wipers and a set responsible for the motion control system.

Another fuse box is installed in the body to the left of the main one. They are responsible for the cooling system and how the engine works. There is also a diagnostic connector. The relay that controls the starter is located either next to the main power supply, or under the hood next to the brake fluid reservoir.

Niva 2121 / Lada 4×4 - fuses and relays

Niva SUV is known under the names VAZ-2121
(VAZ 21213, VAZ 21214) and since 2006 as
Lada 4x4
.
Produced from 1977 to the present with various body modifications, mainly 3- and 5-door station wagons with gasoline engines ( carburetor, injection ).

Gasoline, four-stroke, four-cylinder, eight-valve, in-line, overhead camshaft.

The operating order of the cylinders is: 1–3–4–2, counting from the crankshaft pulley. Power supply system – distributed injection, Niva 2131 engine control – “BOSCH MP7.0” controller (Euro-2 toxicity standards). A catalytic converter is installed in the exhaust system.

On the right side of the engine (along the direction of the car) are located: a receiver with a throttle assembly, a throttle position sensor and an idle speed regulator, an intake pipe and an exhaust manifold, a fuel rail with injectors and a fuel pressure regulator, knock sensors and coolant temperature sensors (for the injection system) , generator, thermostat, starter (on the clutch housing). The air filter housing with mass air flow sensor is mounted on a separate bracket to the right of the engine.

On the left side of the engine are located: spark plugs and high voltage wires, an ignition module, an oil level indicator, an oil filter, coolant temperature and oil pressure sensors (control devices). Front: coolant pump and generator drive (V-belt), crankshaft position sensor.

The cylinder-piston group is the same as for the mod. 21213 (see VAZ-21213 engine). At the toe of the crankshaft there is a drive pulley for the generator and coolant pump with a toothed disk - for reading information by the Niva 2121 crankshaft position sensor. The disk has 58 teeth (the circle is divided into 60 teeth, but two are missing, forming a cavity - this is necessary to obtain a synchronization impulse each revolution of the crankshaft). Camshaft drive cover mod. 21214 is different from the cover mod. 21213 with a boss with a hole for the crankshaft position sensor.

The timing mechanism is driven by a single-row chain. Accordingly, the sprockets of the crankshaft and camshaft, as well as the oil pump drive shaft, are also single-row; they are not interchangeable with engine parts mod. 21213. At the same time, the number of teeth of the oil pump drive shaft sprocket was reduced from 38 to 30 (speed synchronization for the operation of the ignition sensor-distributor is not needed here), thereby increasing the performance of the oil pump (this is necessary in connection with the advent of a hydraulic chain tensioner and hydraulic mounts for valve levers) .

Tensioner shoe mod. 21214 is significantly longer than the shoe mod. 21213. It, like the chain guide, is made of wear-resistant plastic. Their attachment points have also been moved. The rotation axis of the tensioner shoe is located in the lower part of the cylinder block, to the right of the crankshaft sprocket (in its place in the engine model 21213 there was a limit pin).

The tensioner is spring-hydraulic: the preliminary tension of the chain (with the engine off) is provided by a spring, the working tension (after starting the engine) is by the pressure of oil under pressure, which is supplied through a steel tube from the adapter under the emergency oil pressure sensor.

Instead of adjusting bolts, the valve mechanism is equipped with hydraulic supports for the valve levers (hydraulic clearance compensators). They are powered by oil under pressure, supplied through a separate tube from the hole in the camshaft bearing housing near the middle stud of its mounting. Due to the fact that there are practically no gaps in the valve mechanism, the springs that press the valve levers on the mod engine are not installed. 21213. The shape of the camshaft cams is also different.

Additional relay block

This block is located above the gas pedal.

A little higher, above the block, a relay can be installed - a breaker for the turn signals and hazard warning lights.

Separate fuses and relays can be installed under the hood: on cars with ABS, on the left side of the engine compartment near the ABS hydraulic unit, a block with fuses is additionally installed that protect the elements of the anti-lock brake system and the starter relay not far from the starter itself.

DIY power supply replacement

Below we will look at the process of replacing the power supply with your own hands. To replace, you will need a new power supply and a socket head set to “8”.

1. First, open the hood and disconnect the battery.
2. Now, under the instrument panel, find your power supplies. Using an “8” socket wrench, unscrew the two main nuts.
3. Having done this, pry up the power supply and remove them from the studs.
4. If you are replacing an old component with a new one, you must mark all the wires before doing so. Or take a new power supply unit and insert the wires from the old unit into it one by one. To remove the idle wires, pull them by their plugs.
5. To check the functionality of the new power supply, reconnect the battery.

Possible faults

To avoid problems with engine overheating, it is necessary to monitor and maintain the Niva’s cooling system.

You should check the antifreeze level in the expansion tank more often. Due to the reliability of cooling, there are not many malfunctions in it:

1. When the car heats up to maximum in any weather, and the main radiator pipes are cold, the thermostat has broken. The element is not repaired, only changed.
2. Electric fans turn on at random, including when the engine is cold, but if they overheat, they may not start. This means that the sensor transmitting temperature data to the controller has failed and must be replaced.
3. When the indicator on the panel gives inaccurate data or does not show the temperature, you need to change the second sensor located in the cylinder head.
4. The fluid level in the tank is constantly decreasing. It is necessary to look for and eliminate leaks in the pipes or in one of the radiators.

It is important to periodically check for play in the water pump shaft. Its appearance indicates wear of the bearing; it is necessary to change the pump as soon as possible.

Replacing fuse Lada 2131 (VAZ 2131)

Every car has a fuse box that is responsible for the operation of certain components of the vehicle. If certain fuses fail, the operation of some elements becomes impossible, but if the unit itself breaks down, the vehicle simply will not be able to continue moving.

The fuse block (hereinafter referred to as the fuse block), unlike traditional models of the domestic automobile industry, is located in the vehicle interior. In particular, it is located on the driver's side under the steering wheel.

If any electrical circuit element in a car stops working (lamps, interior lights, heater, power windows), then car owners first check the power supply elements.

As a rule, the problem is resolved by replacing the fuse.

What does the power supply circuit itself look like? This question may be of interest to Niva owners. Below we will look at the electrical circuit of the unit with a description of all the components responsible for the operation of certain devices in the car.

In accordance with the diagram, we will consider the meaning of the BP elements. This electrical circuit is universal for all Niva cars.

It should also be noted that in VAZ 21214 injector cars there is another power supply unit with injection system components. It is located separately from the main power supply on the left side under the steering wheel.

In the case of the first described power supply unit, if the elements of the device begin to fail, this will in no way threaten the performance of the car, of course, with the exception of breakdowns of some components. However, in the case of the second power supply, if at least one component shorts out and does not work, the VAZ 21214 injector engine will not start.

Weaknesses of the VAZ 21214 engine

Cylinder block. This weak point appears on various models of Nivov engines, including the previously discussed 21213. Due to insufficient quality control, the assembly unit is manufactured with a high percentage of factory defects. In short, the drilling depth of the intake manifold stud holes is not maintained, causing the holes to meet the camshaft stud holes.

In this way, L-shaped through channels are obtained. After installing the studs at the factory, the connections remain sealed for some time and the problem is not identified when the quality control department employees accept engine tests. After the sale of new cars with low mileage, during sharp braking, oil begins to seep through the studs onto the hot intake manifold, so much so that smoke from the oil burning in the manifold pours out from under the hood, and accordingly, there is nothing to breathe in the cabin.

A sketch for the technical specifications for eliminating oil leaks from under the exhaust manifold studs.

1. Remove the GC cover;
2. Unscrew the two studs securing the bearing housing (see sketch) and remove oil from the threaded holes;
3. Thoroughly degrease the holes and stud;
4. Apply sealant UG-10 or its analogues to the lower threads of the studs;
5. Place the studs in place;
6. Tighten the bearing housing nuts;
7. Install the cylinder head cover;
8. Wait at least 30 minutes for the sealant to set.

The water pump (pump) is characterized by frequent failures on new cars after 2,000 km.

Due to poor quality, oil seals require more frequent replacement than required according to the operating manual.

The generator has a high probability of failure. As a rule, it burns out even on new cars that have not reached 4,000-10,000 km.

The starter has a low service life without repair.

On a gearbox, one of the common defects is the fifth gear slipping out. In addition, the gears are not fully engaged.

The valve cover gasket loses its properties over time and allows oil to leak out.

The connections of the cooling system pipes in the places where the clamps are installed are not reliable and lose their tightness very early, which is fraught with loss of antifreeze.

The radiator is leaking. The problem occurs due to the appearance of cracks in the radiator pipe package, accompanied by loss of coolant. This defect has become widespread.

The thermostat does not provide thermal conditions for the coolant in the engine cooling system. The manifestation of this problem is no exception. The cause of the defect is a failure of the valve mechanism inside the thermostat. To check that the thermostat is working properly, after starting the engine, simply place your palm on the lower (outlet) hose, through which hot antifreeze circulates into the radiator for cooling. If the thermostat is working properly, after some time the hose should become hot; if the hose remains cold, the thermostat must be replaced.

The expansion tank cracks and antifreeze leaks out. The appearance of cracks occurs due to the failure of the steam-air valve in the tank plug due to increased pressure.

Vacuum brake booster (VUT). Manifested by a stiff brake pedal. The speed may fluctuate when the brake pedal is pressed, as well as hissing. The problem is solved by replacing failed rubber products and replacing clamps in connections.

Mounting blocks for lada 4×4 2021

The main and additional units are located in the cabin to the left of the steering wheel, under the instrument panel. The blocks contain fuses of the “Cylinder” size, ten and six fuses, respectively. The ratings and purpose of the fuses are indicated in Table 4 “Circuits protected by fuses”:

Additional blocks for vehicles with ECM

On vehicles with an ECM, a block (Fig. 45) with four fuses is additionally installed on the left side of the front end under the instrument panel, which protect the elements of the injection systems. (to the right of them is the diagnostic connector) A faulty fuse is determined by the failed circuits that it protects, in accordance with Table 4.

TABLE 4 (for Fig. 45)

To connect and protect the ECM circuits, a “safety line” type wire is used, which is part of the ignition system wiring harness and is connected directly to the battery. The circuits protected by this wire are listed in Table 5.

VAZ 21214 engine modifications and their differences

*21214-32 – has fuel pipes with quick connectors, a flywheel for the clutch of 215 mm (200 mm on other models).
The geometry of the cylinder block 21214 and 21213 is the same. There are no liners in the cylinders. Due to the use of an ejector, the configuration of the front engine cover has been changed to accommodate the installation of a crankshaft position sensor. To mount the power steering, a hole is made on the block for installing a bracket; in addition, there is a threaded hole for installing a knock sensor, as well as threaded holes with studs for mounting the ignition module bracket.

The ShPG came from 21213. Crankshaft 21213-1005015 sets the piston stroke to 80mm. The crankshaft pulley is distinguished by the presence of teeth along the outer diameter for the operation of the crankshaft position sensor. The latest internal combustion engine models are equipped with a damping pulley (21214-1005058-10). The presence of a damper made it possible to reduce the load on the crankshaft to prevent cutting of the key, and also make the operation less noisy.

Cylinder head 21214-1003011-30 (36) was modified from the head from 21213. For modification, it was necessary to introduce holes for installing a phase sensor and studs for mounting the intake receiver. To install hydraulic compensators, bosses are cast in the head and have threaded holes in them. With the introduction of hydraulic thermal gap compensators, adjusting bolts were eliminated from the head design.

Oil under pressure is supplied to the hydraulic compensators through separate pipes. There are two types of heads: Russian 21214-1003015 and Canadian 21214-1003015-30. The differences between the heads are as follows: in the first, the diameter of the threads in the holes for hydraulic compensators is M18/1.5, the wells for hydraulic compensators do not have drainage holes;

the second ones have M24x1.5 holes, and the wells have drainage holes (the markings are made in the casting). Interchangeability of heads, as well as hydraulic supports of old and new designs, is not possible. A new oil rail 21214-1007180-30 made of stainless steel is used, supplying oil to the hydraulic compensators. Interchangeability with ramp 21214-1007180 is maintained.

Valve levers 21214-1007116-30, in contrast to the previous 2101-1007116, have a smaller radius (11 mm) of the platform support interacting with the camshaft cam, as well as an additional groove on the side of the hydraulic compensator. Both lever options are interchangeable.

In the timing camshaft drive, instead of a double-row chain, a single-row chain 21214-1006040-03 is used on rollers and bushings. Single-row sprockets for the chain are taken from the 2123 engine. The oil pump sprocket has the number of teeth reduced to 30 to increase the performance of the oil pump and improve the operation of the hydraulic chain tensioner and hydraulic compensators.

The camshaft 21214-1006010 is original with a modified cam profile and can be interchanged with the shaft from 21213.

The 80 amp generator is the same as the 2112, with a slight difference in the diameter of the pulley 80 mm for the drive belt 2107-1308020 (944 mm).

The exhaust manifold can be made of cast iron or stainless steel. The cast iron manifold is made by casting. The stainless steel manifold version has a welded design. A welded manifold is lighter and heats up quickly, which is good for the operation of the catalyst located in the manifold. In addition, an oxygen sensor is installed in the exhaust manifold.

The intake manifold and fuel rail (2123-1144010-11) were borrowed from the 2123 engine. The injectors of the fuel injection system are SIEMENS VAZ 20734 (yellow), injectors (0280 158 110) were installed on early engines.

Ignition module from engine 2112.

Electronic control is carried out by the BOSCH MP 7.9.7 ECU. or JANUARY 7.2 depending on the year of manufacture and modification of the internal combustion engine.

The cooling system began to be assembled using gaskets with an elastic polymer bead, which improved the tightness of the system. The water pump (pump) includes an oil seal (cuff) that is more resistant to wear and loss of properties.

Replacing the heater valve VAZ 21214 Niva without draining antifreeze

Niva cars sometimes have problems associated with the failure of some parts of the cooling system, such as a thermostat or pump. If they break down, they are replaced as an assembly, fortunately they are not expensive. Also a common problem are leaking hoses or a cracked expansion tank, which also needs to be replaced.

But there is another problem with the VAZ 21214, a leaking heater valve. Because of this, there may be a smell of antifreeze in the cabin, wet floor mats on the front passenger side, or the heater may not work.

There are several ways to replace a faulty faucet:

• complete draining of antifreeze from the system;
• clamp the stove pipes with special clamps;
• Place your Niva on a slope, with the hood down.

But there is another option that is more clear and simple. To do this, you need to disconnect the pipes going to the stove under the hood, point them upward and fix them in this position. The next step is to remove the stove itself:

1. unscrew the console;
2. disconnect the latches securing the stove;
3. there is no need to disconnect the buttons;
4. move the radiator assembly, along with the tap and pipes, towards the driver;
5. we take out the entire structure through the space between the steering wheel and pedals;
6. That's it, you can change the tap itself.

After replacement, reassemble in reverse order. As you can see, this operation is quite simple, and antifreeze will not leak into the cabin. And the procedure takes only 40 minutes, even for an unprepared person.
