What is the reason for the unqualified safety monitoring of c30 electronic throttle in Great Wall?

The ECU monitors the functions of the system, and if a fault is found, it will light the system fault indicator to remind the driver of the system fault. At the same time, the electromagnetic clutch is separated from the clutch, and the throttle is no longer controlled by the motor. The throttle valve returns to a small opening position under the action of the return spring, so that the vehicle can slowly drive to the maintenance site.
