Diagnostics VAZ himself?! - It's simple! Diagnostics of the electoral system of automatic control of the VAZ engine. Option facilities of an electronic engine control system (ESAU-D) car VAZ codes VAZ 2111

Availability on-board computer On the car allows you to identify malfunctions on time, take appropriate measures before the breakage has become serious and expensive in elimination.

Here the main thing is to be able to correctly read error codes in the diagnosis of VAZ 2114. Not everyone understands what the car indicates, issuing certain designations. Therefore, today we will try to tell about the most common mistakes codes, and we note that each of them means.

Self-Diagnosis

Immediately, we note that the result of the diagnosis with your own hands in the conditions of its own garage and on specialized car services - somewhat different. Stations maintenance Have at their disposal all the necessary equipment with which the maximum number of error codes from the onboard computer of your car is calculated.

Self-diagnosis with its own hands will allow to achieve a certain positive result. But alas, to detect all errors, it turns out in extremely rare cases.

Nuances of self-diagnosis

Indications for self-diagnosis and access to specialized hundred will be different, error codes are also displayed differently. Therefore, consider today two options.

It is not necessary to use an on-board computer to diagnose malfunctions in the machine. Not all VAZ 2114 owners know about this method, because we will tell about it.

It consists in the following actions.

1. Sit down driver chair And hush the odometer button.
2. Then turn the ignition key to the first position.
3. Release the odometer button. After that, the arrows will start running.
4. Cleash the button again and disconnect. This will allow you to see which version of the firmware is used in your case.
5. Three times hold down, and then release the button. So you will see codes indicating any errors in the work of the car.

Since this is not specialized equipment, codes will be presented in this case as two-digit designations, not four-digit.

We now consider the most popular errors that are found with such diagnostics, and we will figure it out that what code means. Even without an on-board computer, you can detect faults on the VAZ 2114 by odometer codes.

We offer to familiarize yourself with them on the table.

It is important to take into account the fact that errors can develop. For example, if your car has malfunctions, indicating code 4 and 1, the device odometer will show the figure 5.

Plus to everything, all fault codes will be stored in memory until you manually drop them. To do this, turn off the terminals from the battery, while holding the ignition on, wait a few seconds and connect it back. Do not forget to do it, features, if you are going to go to the diagnostics per hundred. They will find these mistakes and will eliminate them, although in fact you have already done before yourself. Pay extra money? No, it is not worth it.

Side computer codes and their meaning

Now let's talk about common error codes that can be identified by diagnosing the onboard computer of your VAZ 2114. It should be borne in mind that it is about electronics, which is also sometimes capable of working incorrectly. But, as practice shows, in the overwhelming majority cases, error codes on the onboard computer correspond to real problems by car.

Learn every mistake incredibly long. Therefore, in this table we collected the most common, with which the owners of the VAZ 2114 are found regularly.

The topic of this article will be the diagnosis of tidy on the VAZ 2110, 2111, 2112.

In order to start the self-diagnostic mode of instrument combinations, it is necessary to turn on the ignition at the same time to hold the button dropping the daily mileage.

How to understand that the mode is started? Everything is very simple, the oil pressure light bulb will begin to burn, the battery icon, the fuel warning lamp and the Chek light bulb (check). In this case, all the arrows begin to move from the initial position to the maximum, and this process is repeated. So you can check the operation of all the bulbs, appliances, arrows.

When you click the button to reset the run per day, the error code will appear.

To reset this error, you need to hold and hold the button, which is reset the daily mileage. While the error is not reset to 0.

To verify that the errors have dropped, repeat the procedure: We enter the mode - Diagnostics of the VAZ 2110 tidy (while the ignition is switched on and hold the button dropping the mileage); Press three times the running button and look at the bortovic screen. It should show 0.

This was decided. But, now it is necessary to find out that we have revealed in case of self-diagnosis of instrument combinations. To do this, you are presented table.

If the number is different, for example, as we have, it means that the errors are somewhat and the computer shows their sum: 6 (2 + 4), 10 (2 + 8), 12 (4 + 8), 14 (2 + 4 + eight).

The whole process can be viewed on the video below:

With errors in self-diagnosis of combinations of instruments of VAZ 2110 figured out, but here you can see, (when the engine light lights) yourself.

In this article, we will tell you how to simply carry out independent computer diagnostics, as well as the accompanying car repair of VAZ (2105, 2107, 2108, 2109, 2110, 2112, 2114, 2115, prior, Kalina).

If the error of the Check engine caught fire on your car ( check Engine) Or you are concerned about fuel consumption, read the article, we will teach to identify such implicit problems.

If you do not pull the engine, the failures appeared, or the car twisted, the problem may also be in the electronics of the car or sensors. Also, you should not chop off my shoulder and run into the car service, perhaps the problem is solved very simply, with minimal material costs. We read our article.

So, let's begin…

No car, especially the Russian car production is not insured against malfunctions. This most unpleasant in this situation is - if the problem is not explicitly character, such as faulty electronics or sensor. The first idea in such a situation is to immediately flee to the auto electrician, let him decide these over complicated, it would seem problems. But! ... Is it worth overpaying such money for the work with which any car enthusiast can cope at home, using a laptop or even with a mobile phone!?
Each injection car without exception has a diagnostic connector, VAZ cars after 2004, it looks like this (see photo). Most often the connector is located under the car's steering column.

In order to connect a car to a laptop, a special adapter is needed (see photo).

Diagnostics of cars VAZ

Section 2 - "Diagnostics" consists of the following parts:

General information

Information on the procedure for conducting diagnostics, security measures and DST-2M diagnostic instrument. Also, a description of the electrical connections of the engine control system and the purpose of the control of the controller-ra connector are also.

Part "A" and diagnostic maps "A"

Contains the initial information on the procedure for conducting diagnostics, including "checking the diagnostic chain", diagnostic cards for malfunction signaling devices, measures in case of the case of impossibility to start the engine and other general cards.

Maps of fault codes

Map data are used if when checking the diagnostic circuit, a malfunction code is detected in the memory of the controller. If there is more than one code, the analysis and troubleshooting must always be started with CO-Dov R0560 (incorrect battali voltage) or P0562 (pony-feminine voltage of the aircraft).

Part "B". Diagnostic maps of faults.

In the absence of a malfunction code or its impermanent, this part helps the mechanics to determine the malfunction. In these cases, diagnostics should also begin with a diagnostic chain verification.

Part "C" and diagnostic cards "C" (Pro-Verk Maps of the engine control system).

This part contains information on verifying the specific elements of the engine control system, as well as by their maintenance. It has information on the elements of the fuel supply system, according to the ignition system, etc.

General

Diagnostics of the engine control system with distribution-free fuel injection is quite simple, provided that it is aware of the order of it.

Diagnosis does not require special knowledge in the field of electronics and computing equipment. Up-to-consuming basic concepts Electrical Equipment and Availability Skill Reading Simple electrical schemes. In addition, it is necessary to have experience with a digital multimeter. Once it comes up, it is necessary to understand the basics of the engine-body.

The first and most important condition for the successful diagnosis of malfunctions of any system is to understand the principle of its work. Before repairing the repair, it is necessary to clearly imagine what a good condition differs from faulty.

Introduction to Section 1 of the Guide "Device and Re-Mont" is a good start to understand the work of the SIS-theme and its elements under normal conditions.

In the descriptions of diagnostics and in diagnostic maps, certain diagnostic tools are used (see Appendix 2). These diagnostic tools are used in concrete purposes, and diagnostic maps describing the procedure for diagnostics are based on the use of these funds.

Speaking about the means of diagnosis, it is important to remember that none of the special diagnostic tools will replace Checkle. The tool and diagnostic tools are not performed by di-agnity per person and do not exclude the need for dia-gnostic maps and in the description of the procedure for conducting diagnostic.

We should not forget that behind the electronics is the basic engine internal combustion. The efficiency of the engine control system depends on the serviceability of mechanical systems.

As a reminder, a number of deviations of malfunctions are given below, which may be erroneously attributed to the electronic part of the engine control system:

Insufficient compression;

Air surface;

Restriction of the passability of the release system;

Deviations of the phases of gas distribution caused by wear of parts and improper assembly;

Poor fuel quality;

Non-compliance with the timing of the versatility.

2.2 Precautions for diagnosis of cars VAZ

When working on a car, you must follow the following requirements.

1. Before dismantling the controller, it is necessary to follow the mass of the mass of the mass from rechargeable battery.

2. The engine start is not allowed without a reliable sub-key of the battery.

3. It is not allowed to disable the battery from the onboard network when the engine is running.

4. When charging, the battery must be disconnected from the on-board network.

5. It is necessary to control the reliability of the contacts of the wiring harnesses and maintain the cleanliness of the battery terminals.

6. The design of the pads of the wiring harnesses of the UP equation system is involved only at a certain orientation.

With proper orientation, the joint is performed without effort. The articulation with improper orientation may be at the failure of the pads, module or other elements of the system.

1. It is not allowed to join or dismember the pad of ECM elements when the ignition is turned on.

2. Before carrying out electric welding work, it is necessary to disconnect the wires from the battery and the co-boat from the controller.

3. To exclude corrosion of contacts when cleaning the engine of water with water under pressure, do not direct the spray-tel to the elements of the system.

4. To eliminate errors and damage, good nodes, the use of instrumentation not specified in the diagnostic maps is not allowed.

5. Voltage measurements to perform with a digital voltmeter with a nominal internal resistance of more than 10 MΩ.

6. If it is provided for the use of a probe with a con-told light bulb, you must use a lamp of small power (up to 4 W). The use of large power lamps, for example, from the headlight is not allowed. If the power of the probe lamp is not known, it is necessary by the simplest test lamps to make sure that its use for the controller circuit con-tribes.

To do this, it is necessary to connect the exact ammeter (digital multimeter with low resistance) follower, but with a tube lamp and submit to the "lamp - ammeter" circuit feeding from the battery (Fig. 2.2-01).

If the ammeter shows the current less than 0.25 A (250 mA), the lamp is safe. If the ammeter shows the current of pain-neck 0.25 A, the use of the lamp is dangerous.

7. The engine control system uses a controller with an 81-terminal connector, which is in a hard-to-reach place. Since the cell inside the connector pads are not available for connecting external measuring instruments, it is necessary to use special signaling of signaling system for pro-junction of the inspection of the injection circuits (Fig. 2.2-02) connected between the controller and the wiring harness.

8. Electronic devices Motor control systems are vulnerable to electrostatic discharges, so when working with them, especially with the controller, it is necessary to be careful.

ATTENTION. To prevent damage to the electrostatic discharge, it is forbidden to break up the metal housing of the controller and touch the plugs of the connector.

2.1 Description of on-board diagnostics

Under the "on-board diagnostics" means a program of pro-gram-hardware (controller, sensors, execution mechanisms), which performs the following tasks:

1) Definition and identifying errors of the functioning of the ECM and the engine, which lead:

To exceeding limit values \u200b\u200bfor the toxicity of from-working gases of cars, which are determined by the actative currently in the appropriate country with ecologic standards for passenger cars;

To reduce the power and torque of the engine, an increase in the fuel consumption, the deterioration of the driving qualities of the AV-Tomobil;

To the failure of the engine and its components (the trough of the pistons due to detonation or damage to the catalytic neutralizer in the event of skips of the fuel and air mixture).

2) Informing the driver about the presence of a malfunction to turning the troubleshooting warning.

3) Saving malfunction information. At the time of the arrival in the memory of the controller, the following information is entered:

The malfunction code according to the international classification (see Table 2.3-01);

Status flags (features) characterizing the fault at the time of the session of information exchange with the diagnostic-Kim DST-2M instrument;

The so-called stop frame is the values \u200b\u200bof the parameters important for Esud at the time of the error registration.

The fault codes and the associated additional information substantially facilitate specialists from troubleshooting in the engine control system.

4) Activation of emergency mode of operation of the ECM. When a malfunction is a failure, the system to prevent the non-negative consequences (listed above) is moving to Ava Riyan modes. Their essence is that when it fails, the controller uses a sensor or its circuit to control the engine, replacing the values \u200b\u200bstored in the PPZ. At the same time, the car will be able to up to the maintenance station.

5) Ensuring interaction with diagnostic equipment. On the presence of a malfunction, the onboard dia-gnostic system reports on the inclusion of the alarm. The on-board diagnostic system must then provide with the help of special equipment to obtain diagnostic information stored in the controller memory. To do this, a serial information transmission channel is organized in the engine control system, which includes the ECM controller (as a transceiver role), a standardized dealer for connecting a diagnostic device (Fig. 2.3-01, 2.3-02) and connecting their wire ( line). In addition to the pads, the information transfer protocol and the format of the transmitted messages are also standardized. In addition to obtaining information on the identified faults and state of the system of the installation of the engine, the system of on-board diagnostics allows you to perform a number of verification tests by controlling the performing mechanisms.

ATTENTION. If an immobilizer is not installed on the car, then to diagnose the engine control system using the DST-2M device, it is necessary to connect the contacts "18" and "9" in the block connected to the immobilizer control unit.

The main component of the on-board diagnostic system is the ECM controller. In addition to its main task (package of burning processes fuel mixes) He feels self-diagnosis.

When performing this feature, the controller monitors signals of various sensors and actuators of ECM. These signals are compared with control values \u200b\u200bthat are stored in the controller memory. And if any signal goes beyond the control values, the control-lever evaluates this state as a malfunction (for example, the voltage at the output of the sensor was zero - a short circuit for mass), generates and writes in memory of the soup-side corresponding diagnostic information ( See yourself), includes a malfunction signaling device, as well as a transition to emergency modes The works of Esud.

The system of on-board diagnostics begins to function from the moment the ignition is turned on and stops after switching the controller to "Stand By" mode (occurs after turning off the main relay). The moment of activating a particular diagnostic algorithm and its work is determined by the corresponding engine operation modes.

Diagnostic algorithms can be divided into three groups:

1) Sensor diagnostics. The controller tracking the sensor output value of the output signal determines the nature of the non-green

2) Diagnostics of ECUD executive mechanisms (Drying diagnostics). The controller checks the circuit of the control on the break, closing the mass or power supply.

3) Diagnosis of ECM subsystems (functional diagnostic style).

In the engine control system, it is possible to distinguish not-how many subsystems - ignitions, fuel feeds, maintenance of idle speed, neutralization of exhaust gases, trailing the vapor of gasoline, etc. The functional diagnosis is to conclusion about the quality of their work. In this case, the Si-stem is monitored not for separately taken sensors or expansion mechanisms, and beyond the parameters that ha-capaty the work of the entire subsystem as a whole. For example, the quality of work of the ignition subsystem can be judged by on-cast ignition skipping in the combustion chambers of the engine-la. Adaptation parameters of fuel feeds provide information on the state of the fuel subsystem. Each of the subsystems presented their requirements for the magnitude of the maximum permissive deviations of its parameters from average values.

Fault signaling device

The troubleshooting warning device in VAZ-11183, 21101 is in a combination of instruments.

Turning on the signaling device signals the driver that the onboard diagnostic system has detected the malfunction of the ECM and the further movement of the car occurs in Avarine mode. In this case, the driver is obliged as soon as possible to provide a car at the disposal of maintenance specialists.

The flashing of the alarm indicates the presence of neis-rule, which can lead to serious damage to the holes of the ECM elements (for example, ignition skips are able to damage the catalytic neutralizer).

When the ignition is turned on, the alarm must be tanned - thus the ECD checks the function of the lamp and the price of control. After starting the engine, the alarm must go out if there are no conditions for its inclusion in the controller's memory.

To protect against accidental, briefly showing errors that can be caused by the loss of contact in electrical connectors or unstable work Motor, the signaling device is turned on through a certain period of time after detecting the ECM failure. At the current gap, the on-board diagnostic system checks the presence of a malfunction.

After eliminating the causes of the malfunction, the bundle warning device is turned off after a certain delay time during which the fault does not appear, and provided that there are no other fault codes in the controller's memory requiring the signaling device.

When cleaning (deleting) malfunction codes from the controller memory using diagnostic equipment Sig-Valveor goes out.

Procedure for performing car diagnostics VAZ

All diagnostic works should always be started with "checking the diagnostic chain"

Checking the diagnostic circuit provides an initial system check and then refers mechanics to other manual cards. It must be the starting point of all works.

All management is constructed according to a single scheme, in accordance with which the test of the diagnostic chain refers furs to certain cards, and those, in turn, can be alleged to others.

It is necessary to strictly adhere to the sequence specified in the diagnostic maps. Violation of the diagnostic sequence can lead to incorrect conclusions and replace good nodes.

Diagnostic maps are built on the application of the DST-2M diagnostic device. It provides mechanics in-formation about what is happening in the engine control system.

The DST-2M device is used to control the ECM. The DST-2M device reads and displays the information transmitted by the controller to the diagnostic shoe.

Checking the diagnostic chain

After inspection of the subcontrol space, the first step of all diagnostics or search for the causes of non-compliance with the norms of toxicity is the test of the dia-Gnostic chain described in section 2.7a.

The correct procedure for diagnosing a malfunction is prescribed by the following three main steps:

1. Check the performance of the on-board system diagnostics. Check is carried out by performing a test of the diagnostic chain. Since this test is a starting point of diagnostics or searching for the non-fulfillment of the norms of toxicity, it is always necessary to clean it from it.

If the onboard diagnostics does not work, checking the diagnostic chain displays to a specific diagnostic car. If the onboard diagnostics works properly, go to step 2.

2. Verification of the availability of current non-English codes. If you have current codes in the controller's memory, you must contact the dia-gnostic cards with the corresponding numbers. In the absence of codes, go to step 3.

3. Control of the data transmitted by the controller. To do this, read information using the DST-2M device.

Description of the device and the parameters displayed by them below. Typical parameter values \u200b\u200bfor specific operations are given in Table 2.4-01.

Casodies of malfunction of cars VAZ 2110, VAZ 2112, VAZ 2114, 2115, Lada Kalina, Prior you can find

VAZ car diagnostic maps

Many car owners of the VAZ 2110, especially those who else without worked driving and repairing "dozens" fall into a light panic, if on, seemingly, a serviceable car suddenly lights up "Check", the on-board computer starts to issue an error.

Usually they are expressed using the letter P and digital four-digit code. Naturally, error codes for VAZ 2110 is not difficult to find in special tables to understand which systems should look for the cause. However, often decoding is very foggy, it is not clear what to do next?

Electronics

Consider some, especially annoying error codes that, as if do not affect the speed, but constantly remind that with VAZ 2110, perhaps something is wrong. These include:

Crankshaft and camshaft

• the code 0335 speaks of a malfunction of the crankshaft position sensor. Therefore, seeing 0335 on the computer, you need to check whether the signal is from this sensor. Having found that the signal is weak, you can help changing air flow, if it is excessive (above maximum). After that, the error 0335 should disappear;
• seeing the 0340 error, know that the camshaft position sensor is most likely defective. Although in fact, if even highlights 0340, the camshaft itself can be good, the car works as usual. But when the numbers 0340 do not disappear while the engine is running, you should carefully inspect this node.

Read more about the operation of the crankshaft sensor, you can read in this material:

Electrical equipment

For malfunctions, VAZ 2110 should be reacting whenever possible. By the way, this can signal the code 1602, even though its decryption sounds like the disappearance of the on-board network in RAM.

Sometimes it is enough to reset the error 1602, and it will no longer appear. Someone calls these numbers "good", 1602 may appear after disconnecting the battery, due to the voltage jump when the engine is started (for example, in the cold). However, if 1602 "pops up" constantly, you need to look for a network break.

Initially, try to clean the battery terminals, secure them well. Did not help? Check the circuit starting from "+" battery, be sure to - fuse, fuse.

And also inspect the mass of the ECU, DPDZ. There are cases when code 1602 appears due to the fact that the security alarm blocks the chain of the controller, and it gives it an error every time. You should contact the installer of your alarm.

Idling

Code 0505 indicates a malfunction of the idle regulator. Moreover, 0505 is most often "issued" when the start of the engine is carried out when the gas pedal is pressed. These often suffer from drivers, recovered from the carburetor VAZ 2110 to the injection.

However, 0505 also occurs if the ignition module is faulty, candles, there are wiring breaks or engine speeds are not those that set the xx regulator.

If you celebrate cotton in the silencer, then this may also testify to the displacement of the crankshaft gear. Code 0505 can be displayed both one and from 0300 (skipping in cylinders).

Throttle valve

Two unpleasant errors - 0122 and 0123 The on-board computer issues when there is a throttle sensor malfunction. Moreover, 0122 will be highlighted if this sensor has a low signal level, and 0123 - if high.

Both one and the other, naturally, is not good. Especially if the readings of the onboard computer are accompanied by increased turns on idling, jerks on small revolutions and failures. In this case, the sensor replacement does not always help.

If the codes 0122, 0123 are issued, check the signal and feeding wires to the cliff, and also pay attention - there is no suction through the nozzles rings. Remember: The main enemies of the DPDD are washing the engine as well as the manufacturer, since the marriage here gives a lot.

The following material is dedicated to the propagated malfunction of the throttle position sensor:

Oxygen sensor

It is quite difficult for some reason to find in tables-decodes code 0525, and this is just an error, differently called a lambda probe. And if you have 0525 again on the display, it means not everything is in order with the content of oxygen in the exhaust.

This sensor is not installed on all models of the vase, it gives a signal to the engine as to how much oxygen should be in the fuel system. That this sensor does not cope with its responsibilities, testify.
