Normal Operation
On vehicles without the memory feature, the driver door disarm switch provides a ground signal to the smart junction box (SJB) through circuit CPL28 (VT/BN), the switch, and ground circuit GD126 (BK/WH) allowing entry without setting off the alarm. The switch must operate before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.

On vehicles with the memory feature, the driver door disarm switch provides a ground signal to the driver door module (DDM) through circuit CPL28 (VT/BN), the switch and ground circuit GD126 (BK/WH). The DDM sends a network message to the SJB, which allows entry without setting off the alarm. The switch must operate before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.

Possible Causes
- circuit CPL28 (VT/BN) open or short to voltage
- circuit GD126 (BK/WH) open
- driver door disarm switch
- DDM (vehicles with the memory feature)
- SJB
