Pinpoint Test M: 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 a front door or the liftgate 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
