Test N: The Auto-Unlock Does Not Operate Correctly
PINPOINT TEST N: THE AUTO-UNLOCK DOES NOT OPERATE CORRECTLYNormal Operation
The driver door module (DDM) energizes the unlock relay based on input from the door ajar switches and the vehicle speed signal. The DDM unlocks the doors when the following conditions are met:
- The vehicle speed has exceeded 5 km/h (3 mph) then dropped to 0 km/h (0 mph) (vehicle stopped).
- The key is turned to the OFF or ACC position.
- The LH front door is opened within 10 minutes of the key being turned to the OFF or ACC position.
The auto-unlock feature is cancelled if the doors are locked with the door lock control switch or the remote keyless entry (RKE) transmitter within the 10 minute active window. After the 10-minute active window expires, the auto-unlock feature does not unlock the doors if the driver door is opened.
The instrument cluster (IC) sends the vehicle speed signal over the standard corporate protocol (SCP) network to the DDM. If the DDM does not receive the vehicle speed signal or it is invalid, the DDM will set DTC U1041.
This pinpoint test is intended to diagnose the following:
- Door ajar switch input
- Vehicle speed signal message
- DDM
