Diagnosis Procedure

WARNING: This page is about a different car, the 2012 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

CHECK STEERING LOCK SOLENOID POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect steering lock solenoid connector.
3. Check voltage between steering lock solenoid harness connector M65 terminal 1 and ground.
1 - Ground: Battery voltage

Is the inspection result normal?

YES: GO TO 2

NO: Repair or replace steering lock solenoid power supply circuit.
