Test M: The Smart Unlock Does Not Operate Correctly

PINPOINT TEST M: THE SMART UNLOCK DOES NOT OPERATE CORRECTLY

Normal Operation
The lighting control module (LCM) sends a network message to the driver door module (DDM) that the key is in the ignition. If the DDM does not receive or receives invalid data for the key-in ignition from the LCM, it will set DTC U1135. The DDM monitors the network message, the door lock control switch and the LH front door ajar switch. If the key is in the ignition and the LH front door is open when the vehicle is locked with a door lock control switch, the DDM unlocks the LH front door. The smart unlocking feature unlocks the LH front door 1 second after these conditions are met. The vehicle may still be locked with the key in the ignition using the manual lock button, a remote keyless entry (RKE) transmitter, the keyless entry keypad or a key in the driver door lock cylinder.

This pinpoint test is intended to diagnose the following:
- Driver door ajar switch
- Key-in-ignition switch
- LCM
- DDM
