Pinpoint Test Q: The Smart Unlock Does Not Operate Correctly
Normal Operation
The Smart Junction Box (SJB) commands all doors to unlock based on input from the key-in-ignition switch and door ajar signal. The feature helps prevent the keys from being locked in the vehicle by unlocking the doors if the key is in the ignition and either front door is ajar.
The vehicle can still be locked with the key in the ignition, by using the manual lock rod, a key in the door lock cylinder, keyless entry keypad, or the LOCK button on an Integrated Keyhead Transmitter (IKT).
This pinpoint test is intended to diagnose the following:
- LH front door ajar switch
- RH front door ajar switch
- Key-in-ignition switch
- SJB
