1. Power Door Catch Malfunction 2. Door Handle Lock Switch Malfunction |
When any exterior door handle is lifted, switched ground signals are sent to the keyless entry control module through the door handle switch signal circuits. If the status of the door lock system is Unlock, the power door catches will electrically release after lifting the exterior door handle. If the status of the door lock system is Lock, one of the following inputs will be required before the catch will release.
• | A door unlock switch activation |
• | A door key cylinder unlock switch activation |
• | An active keyless entry unlock command |
• | A passive keyless entry unlock command message is received by the keyless entry control module |
Once the enable criteria have been met, the keyless entry control module will supply power and ground to the door catch motor control circuits and the door will release.
Note:
• Using the power door unlock switch or manually unlocking the doors does not disable the content theft deterrent arm mode. Also, disconnecting the battery or pulling fuses does not disable the arm mode, since the body control module (BCM) stores the content theft deterrent mode status in memory. • If the door catch does not operate both electrically and mechanically, inspect the door catch and associated lock rods for a mechanical obstruction.
