Door UNLOCK Button
When transmitter UNLOCK button is pressed once, transmitter sends an identification code to remote control door lock receiver to unlock driver door. The receiver sends a signal to Door Control Module (DCM) on the serial data line to unlock the driver door. The DCM then unlocks driver door. The Body Control Module (BCM) disarms Universal Theft Deterrent (UTD) system. BCM will also turn on courtesy lights if ambient light is low. If UNLOCK button is pressed again within 10 seconds of driver door unlocking, passenger door will unlock.
