Lock/Unlock
The LH door switch circuit provides input to the LH Door Control Module (LDCM) when the switch is pressed to the LOCK or UNLOCK position. This input allows the LDCM to detect a door LOCK or UNLOCK request. The LDCM provides both power and ground to the LH door lock and unlock switches. When the LH door lock switch is pressed, a ground is supplied through the LH door switch to the LH door lock input which is pulled low. When the LDCM detects low voltage on the LH door lock input, the LDCM will LOCK the LH door. The LDCM will also send a message on the serial data line to the RH Door Control Module (RDCM) to LOCK the RH door. When the LH door unlock switch is pressed, the LDCM will UNLOCK the LH door and also send a message on the serial data line to the RDCM to UNLOCK the RH door. The RH door lock and unlock function operates the same as the LH door except when the RDCM detects low voltage on the RH door lock input, the LOCK or UNLOCK message is sent to the LDCM. Both DCMs provide output control to their respective door lock motor based upon a LOCK or UNLOCK switch input or from a message received on the serial data line from the opposite DCM. The DCMs provide both power and ground through CKT 294 and CKT 295 to the door lock motors. The lock and unlock output operation is similar to each other except that the polarity of the voltage applied to the door lock motors is reversed.
Automatic Lock
Press the OPTIONS button until on the AUTO LOCK appears on the DIC display, then press the RESET button to select the following features:
| • | AUTO LOCK-ON |
| • | AUTO LOCK-OFF |
If the AUTO LOCK-ON feature is selected, the vehicle will automatically LOCK both doors when the transmission is shifted out of PARK (P). In manual transmission vehicles, both doors will LOCK when the vehicle exceeds 10 mph (16 km/h).
The AUTO LOCK-OFF feature will disable the automatic LOCK function.
Automatic Unlock
Press the OPTIONS button until on the AUTO UNLOCK appears on the DIC display, then press the RESET button to select the following features:
| • | AUTO UNLOCK-DRIVER |
| • | AUTO UNLOCK-BOTH |
| • | AUTO UNLOCK-OFF |
If the AUTO UNLOCK-DRIVER feature is selected, the vehicle will automatically UNLOCK the driver door when ignition is turned OFF and the key is pulled OUT of the ignition.
If the AUTO UNLOCK-BOTH feature is selected, the vehicle will automatically UNLOCK both doors when ignition is turned OFF and the key is pulled OUT of the ignition.
The AUTO UNLOCK-OFF feature will disable all automatic UNLOCK functions.
