Engine Control Module Installation Note:

Installation and programming is highly recommended by professional engineers
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 trial operation), the key is turned on to the NO position, and it can be switched back and forth three or four times before starting.
If the car has anti theft function, you need to decode (match) first, this depends on your car and not the computer board.

Engine Control Module Installation Method:

First unload the battery wire a live wire, then install the computer board (circuit board), and then connect the wire.
After the car key turn to NO, do not land the car, wait 1-2 minutes, and then ignite.
If the fire cannot be caught last time, repeat the previous step and try again, or see if there is dust inside the computer board and the computer board plug, if there is any, you can clean it with a clean brush, or check whether the pins are neat, so that the computer board is basically OK.
