Fail-Safe Function: Notes
WARNING: This page is about a different car, the 2010 Nissan Sentra. 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 CVT to make driving possible.
Secondary Speed Sensor
The shift pattern is changed in accordance with throttle position when an unexpected signal is sent from the secondary speed sensor to the TCM. The overdrive-off mode is inhibited, and the transaxle is put in "D".
