Installation precautions:

 

When installing the product, it is important to first identify the cause of the previous computer board failure to prevent the same issue from burning out the computer board again. Check if the voltage is normal (around 12V). It is recommended not to install it above 15V. Check if the circuit is normal and if the grounding is good, otherwise there is a possibility of burning out the computer board. After installing the computer board, turn the key to the NO position and switch back and forth three or four times before restarting. (Correct installation method for computer board: First remove a live wire from the battery cable, then install the computer board (circuit board), and then connect the wire. After that, turn the car key to NO and do not start the car. Wait for 1-2 minutes, then turn on the ignition. If it cannot be turned on last time, repeat the previous step and try again, or check whether there is dust inside the computer board (circuit board) and the plug of the computer board (circuit board). If there is, you can blow it or clean it with a clean brush, or check whether the pins are neat. This way, the computer board can be installed normally!)! )

 

 

If you don't know how to fix it yourself, please seek help from experienced or knowledgeable mechanics

Attention: Before installing a new product, check the cause of the previous computer board failure to prevent the same issue from burning out the computer board again. During installation, check if the voltage and wiring are normal, and if the grounding is good. The normal voltage of the computer board is 12V. Do not install it if it is higher than the normal voltage, otherwise there is a possibility of burning out the computer board.
