Fail-Safe Mode
WARNING: This page is about a different car, the 2003 Infiniti FX45. However, it is still accessible from the selected car via links, so may be relevant.
When malfunction is detected, ECM enters fail-safe mode and MIL lights up. ECM stops electric throttle control actuator control and throttle valve is maintained at a fixed opening (about 5 degrees) by the return spring.
