Fail-Safe Mode

When the malfunction is detected, ECM enters fail-safe mode and the MIL lights up.

CONDITION IN FAIL-SAFE MODE

Engine operation condition in fail-safe mode
The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.
