Car Engine Computer Board Aluminium Alloy 5WY5102E ECM ECU Board Replacement for Joyner 800cc Engines Condition: Not Remanufactured Part Item Type: ECU Engine Control Module Material: Aluminium Alloy + ABS OEM: 5WY5102E, S11 3605010TA Fitment: Replacement for Joyner 800cc Engines 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. 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. 3. 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. 4. Programmability: The engine computer board has programmability, and the working state of the customized engine can be modified through the program. 5. 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. 6. 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 Common troubleshooting: 1 If the fault lamp is on, it indicates that there is a problem with the sensor. 4 If the idle speed is unstable, please check whether the idle motor and throttle valve body are normal and have foreign matters. 5 If it is difficult to start, please check whether the pressure sensor and water temperature sensor are normal. 6 In case of failure to start, please check whether the crankshaft position sensor Speed Sensor is normal. Basic knowledge of circuit board: 1. Product installation: confirm that the product model and specification are normal, install and fix the new circuit board, connect the harness connector, and turn on the ignition switch 3-5 times, switch time 2-3s, closing time 4-6s. 2. Inspection and judgment after installation: whether the idle speed is normal: Hot engine 800-950 rpm, cold engine 1000-1300 rpm; whether the electronic fan is normal: 85℃ on, 90. ℃ off; whether the air conditioner is normal: Open the idle speed to 1100-1300 rpm; whether the exhaust gas of the hot engine is normal: Check the pressure sensor if abnormal; if there is idle speed, adjust the ignition angle appropriately if there is insufficient refueling.
