4. Clear fault code
After troubleshooting the EFI, it needs to be cleared manually or through a diagnostic tool. M310 can be cleared manually,
M125 need to use the ISO15765-4 communication protocol (CAN diagnosis) diagnostic instrument to clear.
4.1 M310 manually clear
a. Unlock the vehicle
b. Turn off the flame switch to "";
c. Start the vehicle, refuel in neutral gear to more than 4000 rpm and hold for 10 seconds;
d. Release the throttle, turn the flameout switch to "", and be careful not to power off the whole vehicle, and wait for more
than 10 seconds;
e. After repeating the above three steps for 4 times, the fault light goes out.
4.2 Use the diagnostic tool to clear
The steps of different brands or models may be different, so please refer to the description of the diagnostic Speedometer
manual to clear the fault code.
●When the engine is running, the fault light does not turn on, and the fault light flashes after the engine is turned off, it is a
historical fault, which will not affect the performance and life of the whole vehicle, and will automatically disappear later.
