Fail-Safe Mode
When the malfunction is detected, ECM enters fail-safe mode and the MIL lights up.
CHECK
| Engine operating condition in fail-safe mode |
|---|
| ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees. |
| ECM regulates the opening speed of the throttle valve to be slower than the normal condition. |
| So, the acceleration will be poor. |
