Remote Control Door Lock Receiver Module System
WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The remote control door lock receiver module system may also arm and disarm the CTD system. When the remote control door lock receiver receives a door lock or an unlock signal from the key fob, the remote control door lock receiver sends a message to the BCM. The message orders the BCM to perform the appropriate door lock/unlock command. The BCM detects the message and performs one of the following functions:
- Locks the doors and enters the armed initiated mode
- Unlocks the doors and enters the ready-to-arm mode
