Pinpoint Test N: The Smart Unlock Does Not Operate Correctly
Normal Operation
The Smart Junction Box (SJB) automatically unlocks all the doors after the doors are locked with a door lock control switch if the key is in the ignition lock cylinder and one of the front doors is ajar.
The vehicle can still be locked by locking the doors with the push button rods, the door lock cylinder or a Remote Keyless Entry (RKE) command from an Integrated Keyhead Transmitter (IKT) or the keyless entry keypad.
This pinpoint test is intended to diagnose the following:
- Key-in-ignition switch
- Door ajar switch input
- SJB (Smart Junction Box)
