ECU Electronic engine control unit JANUARY 7.2 for VAZ 2110-2112

Controller 21114-1411020-31 manufactured by AVTEL has been installed on VAZ tenth series cars since the end of 2005. This block belongs to the Euro 2 environmental standard, i.e. the mandatory presence of an oxygen sensor and adsorber is assumed. Controller 21114-1411020-31 provides pairwise parallel injection. When working with this unit, the vehicle configuration must contain an ignition coil with a 3-pin input, a BOSCH 0 280 218 116 mass air flow sensor and SIEMENS 6393 injectors.

The engine control unit software 21114-1411020-31 has three calibrations in hardware implementation 7.2 A204DM53, A204DM54 and A204DO57. They are usually referred to as 1st, 2nd and 3rd versions. The first two versions are unsuccessful, so VAZ recommends replacing them with the third. This block can be easily chipped, so it is in demand among sports tuning enthusiasts. After several years, a new hardware implementation was created designated as 7.2+, having one calibration A204DP57. The body of the 7.2+ controllers was made by stamping from very thin metal, for which people called this group of controllers “canned food”. The weak point of all types of controllers 21114-1411020-31 is the low quality of the output ignition keys. If the key fails, repairs must be carried out by a very qualified technician, since the key must be soldered to the board with its entire plane to ensure heat dissipation. It is difficult to achieve this and not burn the key when soldering, and therefore, if you are not a master radio installer, it is better to replace the unit with a new one. Dry the interior floor regularly, since the surface of the controller board is not varnished and it is susceptible to dampness.

An electronic control unit (ECU) is a computing device whose main task is to process information coming from input sensors and, based on this information, to issue control commands to various vehicle systems. The operation of systems and assemblies of a modern car directly depends on the correct operation of this “think tank”. Any malfunctions in the electronic unit are immediately reflected in the operation of the power supply, transmission, exhaust system and other elements. Also called: Controller, Brains, ECU, ECM.

Vendor code: 21114-1411020-31

Applicability: VAZ 2110, 2111, 2112 with an 8-valve 1.6L engine with one oxygen sensor

Where is the VAZ 2114 ECU located?

The block is located in the dashboard, directly under the tidy. To replace or dismantle, you need to unscrew the screws and remove the panel from the side, on the passenger side. Through the resulting hole you can see the ECU housing - it is installed inside a steel retainer.

To remove the electronic control unit, you need to unscrew the bolt and carefully pull out the housing, grasping the latch. Of course, it is necessary to turn off the power from the on-board network, otherwise expensive equipment can be damaged. A short circuit is the enemy of any electrical appliance, so be careful. It is advisable not only to remove ground from the battery, but also to disconnect the positive wire.

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

• DPKV (Crankshaft Position Sensor).
• DF (Phase sensor).
• MAF (instant air flow sensor).
• DTOZH (Coolant temperature sensor).
• TPS (Throttle Position Sensor).
• DK (oxygen sensor).
• DD (Knock Sensor).
• DS (Speed ​​Sensor).
• And other sensors.

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

• Fuel system (Fuel pump, pressure regulator, injectors).
• Ignition system.
• Idle speed regulator (IAC, IAC).
• Adsorber.
• Radiator fan.
• Self-diagnosis 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 containing the main calibration readings and engine control algorithm. This memory is not erased when the power is turned off and is permanent. Amenable to reprogramming and chip tuning.
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 device (EPROM). This type of memory can be said to be the protection of the car. It temporarily stores codes and passwords for the vehicle's anti-theft system. The immobilizer and EEPROM are compared with data, after which the engine can be started.

How does the ECU work?

At the heart is a microprocessor, which is responsible for the normal functioning of all key devices. On a VAZ 2114 car, the ECU collects data from sensors:

1. Vehicle speed.
2. Detonations.
3. Lambda probe.
4. DPKV.
5. Air flow.
6. TPDZ.
7. Phases of injection of the air-fuel mixture.
8. Coolant temperatures.

These are reading devices that collect information about the operation of an internal combustion engine. Why does he collect it? It is correct to divide and conquer by the following actuators:

1. Fuel supply system (pump, injectors).
2. Ignition system.
3. Adsorber.
4. Ventilation.
5. Idle air control (yes, yes, this is not a sensor, but an actuator, no need to be confused).
6. Automatic diagnostics.

The block diagram of the electronic control unit on the VAZ 2114 consists of three cascades, each of which has its own memory modules:

1. A RAM unit (random access memory) is a system that has short-term memory. It stores all information about errors that occurred during operation during the current engine start. When the ignition is turned off (and the computer is de-energized), all memory is cleared and filled again the next time it starts.
2. PROM is a programmable read-only memory device. This is the block in which the fuel map (firmware) of the electronic control unit is stored. It also permanently stores information about all system calibration results. And most importantly, this memory contains the algorithm of the internal combustion engine control system. This memory is permanent and is not erased even if the on-board network is completely disconnected. It is this block that is programmed when the “firmware” procedure is performed to improve the characteristics of the VAZ 2114 car.
3. And the last block is the ERPZU. The memory unit is necessary to ensure the normal operation of the anti-theft system on the car. It stores passwords and encodings. Starting the engine is possible only if the data exchanged between the immobilizer and the EEPROM matches.

ECU M74 E-GAS (V8 L1.6 E-4) 2 oxygen sensors

Dear customers, in order to avoid errors when sending an electronic engine control unit (ECU, ECM, controller), in the “Comment” line indicate the toxicity reduction system that complies with Euro 2, Euro 3 or Euro 4 standards, engine displacement and number of valves , number of oxygen sensors, your car model, year of manufacture.

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

The ECU is most often replaced by the following terms: Electronic engine control 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, ECM, ECU, CONTROLLER are one and the same.

The controller (ECU) 11183-1411020-02 (M74) is designed for an eight-valve 1.6-liter engine with Euro-4 environmental standard. This standard is met if the car has 2 oxygen sensors, a neutralizer, an adsorber and an electronic gas pedal. Controller 11183-1411020-02 ensures engine operation in pair-parallel injection mode.

The following firmware versions are available:

Repair and diagnostics of control units

The VAZ 2114 controller often breaks down. The system has a self-diagnosis function - the ECU queries all components and issues a conclusion about their suitability for operation. If any element fails, the “Check Engine” lamp will light up on the dashboard. It is possible to find out which sensor or actuator has failed only with the help of special diagnostic equipment. Even with the help of the famous OBD-Scan ELM-327, loved by many for its ease of use, you can read all engine operating parameters, find the error, eliminate it and delete it from the memory of the VAZ 2114 ECU.

Of course, it is wrong to simply delete errors. Be careful, because malfunctions don’t just appear. A good example is that a friend’s oxygen sensor broke down. And every other day he cuts down the mistake so that “it doesn’t become an eyesore.” But the reason lies in a faulty lambda. But what to do if the ECU does not want to respond to the scanner at all? Then check the following:

1. Is there any mechanical damage to the housing, including oxidation and corrosion?
2. The fuse is working properly, there is voltage and a connection to the power supply minus.
3. Is the device overheating?
