Specification:
Item Type: ECU Engine Control Unit
OE Number: 2739002800, A2739002800
Material: Aluminum alloy + ABS
Fitment:
Replacement for Benz M272 Engine
Features and Applications:
- Control the working state of the engine: The engine computer board is the core equipment of engine control, which analyzes and controls the engine by receiving sensor signals to achieve better fuel economy, reduce emissions and protect the engine.
- Fault self diagnosis: The engine computer board has the function of fault self-diagnosis, which can determine the specific location and type of engine fault by reading the fault code.
- Adaptive control: The engine computer board has adaptive control function, which can automatically adjust the working state of the engine according to different driving conditions and environments to ensure the best performance of the engine.
- Programmability: The engine computer board has programmability, and the working state of the customized engine can be modified through the program.
- Strong protection and anti-interference ability: The engine computer board adopts sophisticated hardware components and efficient software algorithms, which has strong anti-interference ability and high reliability, and can work normally in harsh working environments.
- Complete functions and strong scalability: The engine computer board has rich functions and interfaces, which can communicate and integrate with other vehicle systems (such as transmission, ABS, on-board entertainment system, etc.) to realize intelligent control of the vehicle.
Installation Considerations:
- It is recommended to find a professional auto mechanic to install, programming is required before installation
- When installing the product, pay attention to check the reason for the previous computer board to avoid burning the computer board again with the same fault.
- Check whether the voltage is normal (voltage about 12V) before installing the computer board, it is recommended not to install it above 15V, check whether the line is normal and whether the iron is good, otherwise there is a possibility of burning the computer board.
- After installing the computer board (insert the plug for test operation), turn the key to the NO position, switch back and forth three or four times, and then start.
- If the car has anti theft, you need to decode (match) first, this depends on your car and not the computer board
Workarounds for common failures:
- The fault light indicates that there is a problem with the sensor.
- Repeatedly burn the computer board "ECU" or can't afford to refuel, please check whether the generator voltage is normal.
- If there is a lack of cylinder, check whether the spark plug, ignition line, fuel injection nozzle, etc. are normal.
- If there is idle instability, please check whether the idle motor and throttle valve body are normal and have foreign objects.
- If there is difficulty in starting, please check whether the pressure sensor and water temperature sensor are normal.
-
If it cannot be started, please check whether the crankshaft position sensor "Speed Sensor" is normal.
Circuit Board Basics:
-
Product installation: confirm the product model and specification match, install and fix the new circuit board, connect the wiring harness connector, and turn on and off the ignition switch repeatedly for 3-5 times "Switching time 2-3 seconds, closing time 4-6 seconds"
2 Check and judge after installing the computer board:
1) Whether the idle speed is running normally "800-950 rpm for hot engine, 1000-1300 rpm for cold engine",
2) Whether the electronic fan is running normally "turn on at 85C, turn off at 90C",
3) Is the air conditioner running normally? "Turn on and increase the idle speed to 1100-1300 rpm",
4) Whether the exhaust gas of the heat engine is normal "If there is any abnormality, please check the pressure sensor",
5) There is idle speed, and the refueling is weak, please adjust the ignition angle properly.
