Fail Safe Mode
WARNING: This page is about a different car, the 2002 Nissan Maxima and 2002 Infiniti I35. 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 illuminates. ECM stops electric throttle control actuator control and throttle valve is maintained at a fixed opening (about 5 degrees) by the return spring.
