Fail-Safe Mode

WARNING: This page is about a different variant/trim than selected.

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

FAIL-SAFE MODE DESCRIPTION

Engine operating 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.
