It is recommended to have a professional automotive engineer install the product, programming required before installation 2. Check the cause of previous ECU damage before installation to avoid potential damage 3. Check voltage (around 12V) and ensure proper wiring and good grounding to prevent damage to the ECU 4. After installing the ECU, turn the key to the ON position and switch it on and off three to four times before starting 5. If the vehicle has theft deterrent system, decoding (matching) may be required before installation (this depends on your vehicle, not the ECU) Correct Installation Method of Computer Board 1. Disconnect one battery line, install the ECU, reconnect the battery line 2. Turn the key to the ON position without starting the engine, wait 1-2 minutes before ignition3. If the last time the ignition, and then repeat the previous step, or check the computer board plug inside whether there is dust, if there is a clean brush can be cleaned up, or check whether the pins are neat, so that the computer board installed on the basic OK! Common Failure Problem Solving Method: 1. Fault light indicates that there are problems with the sensor. 2. Repeatedly burn the computer board "ECU" or refueling does not work, please check whether the generator voltage is normal. 3. The phenomenon of missing cylinders, check whether the spark plug, ignition wire, injector nozzle, etc. is normal. 4. If the idling speed is unstable, please check whether the idling motor and throttle valve body are normal and there are foreign objects. 5. If it is difficult to start, please check whether the pressure sensor and water temperature sensor are normal. 6. If the engine fails to start, please check whether the crankshaft position sensor and speed sensor are normal. Circuit Board Basics: 1. Product Installation: Confirm the product model and specifications match, install and fix the new circuit board, connect the wiring harness connector, repeatedly switch the ignition switch 3-5 times, "switch time 2-3 seconds, off time 4-6 seconds".2. Check and judgment 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 "85 ℃ on, 90 ℃ off". (3) whether the air conditioning operation is normal "open idle speed to 1100-1300 rpm". (4) whether the hot exhaust is normal, "if not normal, please check the pressure sensor". (5) If there is idle speed and weak refueling, please adjust the ignition angle appropriately. . Package List: 1 x Engine Control Unit Note: Please check the original part number before purchase and ensure compatibility.
