An electronic engine control unit (ECU) is a “computer” that controls the entire vehicle system. The ECU affects both the operation of a single sensor and the entire vehicle. Therefore, an electronic engine control unit is very important in a modern car.

The ECU is most often replaced by the following terms: Electronic engine management system (ECM), controller, brains, firmware. Therefore, if you hear one of these terms, then know that we are talking about the "brains", the main processor of your car. In other words, the ECM, ECU, CONTROLLER are one and the same.

Where is the ecu (controller, brain)?

The electronic engine management system (ECU, ECM) is mounted under the central dashboard of your car's instrument panel. To gain access to it, you need to unscrew the fasteners of the side frame of the torpedo with a Phillips screwdriver.

The principle of operation of the controller (ECU)

During the entire operation of the engine, the electronic engine control unit receives, processes, manages systems and sensors that affect both engine operation and secondary engine elements (exhaust system).
The controller uses data from the following sensors:

  • (Crankshaft position sensor).
  • (Momentary air flow sensor).
  • (Coolant temperature sensor).
  • (Throttle position sensor).
  • (Oxygen sensor).
  • (Knock sensor).
  • (Speed ​​sensor).
  • And other sensors.

Receiving data from the sources listed above, the ECU controls the operation of the following sensors and systems:

  • (Fuel pump, pressure regulator, injectors).
  • Ignition system.
  • (DHH, RHH).
  • Adsorber.
  • Radiator fan.
  • Self diagnostic system.

Also, the ECM (ecu) has three types of memory:

  1. Programmable Read Only Memory (PROM); Contains the so-called firmware, i.e. a program in which the main calibration readings are loaded, an engine control algorithm. This memory is not erased when the power is turned off and is permanent. Can be reprogrammed.
  2. Random Access Memory (RAM); It is a temporary memory in which system errors and measured parameters are stored. This memory is erased when the power is turned off.
  3. Electrically reprogrammable memory (EPROM). This type of memory can be said to be the protection of the car. It temporarily stores the codes and passwords of the car's anti-theft system. The immobilizer and EEPROM are compared with data, after which the engine can be started.

Types of ECU (ESUD, controller). What ECUs are installed on the VAZ?

"January-4", "GM-09"

The very first controllers on SAMARA were January-4, GM - 09. They were installed on the first models until 2000 of release. These models were produced both with and without a resonant knock sensor.

The table contains two columns: 1st column - ECU number, second column - brand of "brains", firmware version, toxicity rate, distinctive features.

VAZ 2113-2115 since 2003 equipped with the following types of ECU:

"January 5.1.x"

  • simultaneous injection;
  • phased injection.

Interchangeable with "VS (Itelma) 5.1", "Bosch M1.5.4"

Bosch M1.5.4

The following types of hardware implementation are distinguished:

  • simultaneous injection;
  • in pairs - parallel injection;
  • phased injection.

Bosch MP7.0

As a rule, this type of controller is put on the market, it is installed at the factory in a single volume. It has a standard 55-pin connector. Able to work with crossover on other types of ECM.

Bosch M7.9.7

These brains began to be part of the car from the end of 2003. This controller has its own connector that is not compatible with connectors prior to this model. This type of ECU is installed on a VAZ with a EURO-2 and EURO-3 toxicity standard. This ECM is lighter and smaller than previous models. There is also a more reliable connector with increased reliability. They include a switch, which in general will increase the reliability of the controller.

This ECU is in no way compatible with previous controllers.

VS 5.1

The following types of hardware implementation are distinguished:

  • simultaneous injection;
  • in pairs - parallel injection;
  • phased injection.

"January 7.2."

This type of ECU is made for a different type of wiring (81 pins) and is similar to Bosch 7.9.7+. This type of ECU is produced both by Itelma and Avtel. Interchangeable with Bosch M.7.9.7. In terms of software, 7.2 is a follow-up to January 5th.

"January 5.1"

All types of controllers of their type are built on the same platform and have differences most often in the switching of injectors and the DC heater.

Let's look at the following example ECU firmware January 5.1: 2112-1411020-41 and 2111-1411020-61. The first version has a phased injection and an oxygen sensor, the second version differs only in that it has a parallel injection. Conclusion - the difference between the ecu data is only in the firmware, so they can be interchanged.

"M7.3."

Wrong name - January 7.3. This is the last type of controller that is currently being installed at AvtoVAZ. This type of ECU has been installed since 2007. on a VAZ with a EURO-3 toxicity standard.

The manufacturers of this computer are two Russian companies: Itelma and Avtel.
The table below shows ECUs for engines with EURO-3 and Euro-4 toxicity standards.

How to identify an ECU?

To find out how to identify your controller, you will have to remove the side frame of the torpedo. Remember your ECU number and find it among our tables.
Also, some on-board computers show the ECU type and firmware number.

ECU diagnostics

ECU diagnostics is a reading of errors recorded in the memory of the controller. Reading is performed using special equipment: PC, cable, etc. through the diagnostic K-line. You can also get by with an on-board computer that has the functions of reading ECM errors.

For many novice diagnosticians and ordinary motorists who are interested in the topic of diagnostics, information about typical engine parameters will be useful. Since the most common and easy-to-repair engines of VAZ cars, we will start with them. What is the first thing you need to pay attention to when analyzing the parameters of the engine?
1. Engine stopped.
1.1 Coolant and air temperature sensors (if any). The temperature is checked to ensure that the readings correspond to the actual temperature of the engine and air. Checking is best done with a non-contact thermometer. By the way, one of the most reliable VAZ engines in the injection system is temperature sensors.

1.2 Throttle position (except systems with electronic gas pedal). The gas pedal is released - 0%, the accelerator is pressed - corresponding to the opening of the throttle. They played with the gas pedal, released it - it should also remain 0%, while the ADC with a dpdz of about 0.5V. If the opening angle jumps from 0 to 1-2%, then as a rule this is a sign of a worn out dpdz. Rarely, there is a malfunction in the wiring of the sensor. With the gas pedal fully depressed, some units will show 100% opening (such as Jan 5.1, Jan 7.2) while others like the Bosch MP 7.0 will only show 75%. This is fine.

1.3 ADC DMRV channel in rest mode: 0.996 / 1.016 V - normal, up to 1.035 V is still acceptable, everything above is a reason to think about replacing the mass air flow sensor. Injection systems equipped with oxygen sensor feedback are able to correct incorrect MAF readings to some extent, but there is a limit to everything, so you should not delay replacing this sensor if it is already worn out.

2. The engine is idling.

2.1 Idle speed. Usually it is 800 - 850 rpm with a fully warmed up engine. The value of the number of revolutions at idle depends on the temperature of the engine and is set in the engine management program.

2.2 Air mass flow. For 8 valve engines, the typical value is 8-10 kg / h, for 16 valve engines - 7 - 9.5 kg / h with a fully warmed-up engine at idle. For the M73 ECU, these values ​​\u200b\u200bare somewhat larger due to the design feature.

2.3 Length of injection time. For phased injection, a typical value is 3.3 - 4.1 ms. For simultaneous - 2.1 - 2.4 ms. Actually, the injection time itself is not so important as its correction.

2.4 Injection time correction factor. Depends on many factors. This is a topic for a separate article, here it is only worth mentioning that the closer to 1,000 the better. More than 1,000 means the mixture is further enriched, less than 1,000 means it is leaner.

2.5 Multiplicative and additive component of self-learning correction. A typical multiplicative value is 1 +/-0.2. The additive is measured as a percentage and should be no more than +/- 5% on a working system.

2.6 If there is a sign of engine operation in the adjustment zone on the signal of the oxygen sensor, the latter should draw a beautiful sinusoid from 0.1 to 0.8 V.

2.7 Cyclic filling and load factor. For "January" typical cycle air consumption: 8 valve engine 90 - 100 mg / stroke, 16 valve 75 - 90 mg / stroke. For Bosch 7.9.7 control units, a typical load factor is 18 - 24%.

Now let's take a closer look at how these parameters behave in practice. Since I use the SMS Diagnostics program for diagnostics (hi to Alexey Mikheenkov and Sergey Sapelin!), then all the screenshots will be from there. The parameters are taken from practically serviceable cars, except for separately specified cases.
All images are clickable.

And in conclusion, let me remind you that the above screenshots were taken from real cars, but unfortunately the recorded parameters are not ideal. Although I tried to fix the parameters only from serviceable cars.
