Engine Computer Board Accurate Control A2731533079 ECU Board Replacement for Benz GL550 ML550 CLS550

Item Type: Engine Control Module ECU
Material: Aluminum alloy + ABS
OEM: A2731533079
Condition: Non remanufactured part
Fitment: Replacement for Benz GL550 ML550 CLS550 2007 to 2012 M273 Engine (programming is required for installation)
Function and Application:
1. 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.
2. 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.
3. 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:
1. It is recommended to find a professional auto mechanic to install, programming is required before installation
2. 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.
5. If the car has anti theft, you need to decode (match) first, this depends on your car and not the computer board
Correct Installation Method Of Computer Board:
1. First remove a live wire from the battery wire, then install the computer board (circuit board), and then connect the battery wire wire.
2. Hit the car key to NO and do not land the car, wait 1‑2 minutes before igniting,
Troubleshooting Solution:
1. The fault light indicates that there is a problem with the sensor.
4. If there is idle instability, please check whether the idle motor and throttle valve body are normal and have foreign objects.
5. If there is difficulty in starting, please check whether the pressure sensor and water temperature sensor are normal.
6. If it cannot be started, please check whether the crankshaft position sensor Speed Sensor is normal.
Board Basics:
1 Product installation: confirm the matching of product model and specifications, install and fix the new circuit board, connect the wiring harness connector, repeatedly switch the ignition switch 3-5 times switch time 2-3s, closing time 4-6s
2 Check and judge after installing the computer board:
1) Whether the idle speed is running normally heat engine 800-950 rpm, cold engine 1000-1300 rpm,
2) Whether the electronic fan is running normally 85℃ on, 90℃ off,
3) Whether the air conditioner is running normally turn on the idle speed to 1100-1300 rpm,
4) Whether the heat engine exhaust gas is normal If there is abnormality, please check the pressure sensor,
5) If there is idle speed and refueling is weak, please adjust the ignition angle appropriately.
