Test N: The Smart Unlock Does Not Operate Correctly

PINPOINT TEST N: THE SMART UNLOCK DOES NOT OPERATE CORRECTLY

Normal Operation
The smart unlock feature is controlled by the SJB. The SJB unlocks all doors after 1 second if the key is in the ignition and either front door is open when the vehicle is locked with a door lock control switch.

The doors can still be locked by using the manual door lock rod, a remote keyless entry (RKE) transmitter, or the keyless entry keypad.

This pinpoint test is intended to diagnose the following:
- Key-in-ignition switch
- LH front door ajar switch
- SJB
