Fail-Safe Function: Notes

WARNING: This page is about a different car, the 2007 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.

If any malfunction occurs in a sensor or solenoid, this function controls the A/T to make driving possible.

NOTE: Line pressure is set at the maximum in fail-safe mode. Although gear position differs depending on the type of fail-safe modes, CONSULT-II indicates "5th".
