Pinpoint Test L: The Smart Unlock Does Not Operate Correctly

Normal Operation

The Body Control Module (BCM) commands all doors to unlock based on input from the key-in-ignition switch and the door ajar signal. This 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, the keyless entry keypad, or the LOCK button on a Integrated Keyhead Transmitter (IKT).

This pinpoint test is intended to diagnose the following:

- Key-in-ignition switch

- Door ajar switch input
