On some vehicles, the power door lock system is integrated with the Remote Keyless Entry (RKE) system. For information on RKE, see appropriate REMOTE KEYLESS ENTRY SYSTEMS article.
The Body Control Module (BCM) is also referred to as Platform Zone Module (BCM). BCM locks and unlocks all doors by the following conditions:
- Door lock/unlock switch activation.
- Pressing door lock/unlock switch on Remote Keyless Entry (RKE) transmitter.
- Auto door lock function activated.
- Central door unlocking enabled.
BCM is responsible for energizing the door lock/unlock relays.

BCM is capable of setting 3 personalized lock/unlock options/modes. See PROGRAMMING .
