Keyless Entry Receiver: Description and Operation

REMOTE CONTROL DOOR LOCK RECEIVER (RCDLR)

The keyless entry system may also arm and disarm the CTD system. When the RCDLR receives a door lock/unlock signal from the transmitter, the RCDLR sends a class 2 message to the BCM to perform the appropriate door lock/unlock command. The BCM performs one of the following functions:
1. Locks the doors and enters the armed mode.
2. Unlocks the doors and enters the standby mode.
