The ECM calculates and compares the accelerator opening angle command value used for control and the value used for monitoring, after corrected by the brake override system. If the ECM determines there is an excessive output when both the accelerator pedal and brake pedal are depressed in that order, a DTC is stored and the MIL is illuminated.
