Fail-Safe Mode

When malfunction is detected, ECM enters fail-safe mode and MIL illuminates. ECM controls the electric throttle control actuator in regulating throttle opening in order for the idle position to be within +10 degrees. ECM regulates an opening speed of about 5 seconds to an opening of 10 degrees. Therefore, acceleration will be poor.
