BCM Outputs

The BCM directly controls these outputs, plus other systems may request the BCM to control these outputs for certain functions:
^ All Door Lock: When active, supplies voltage to the door lock actuators and locks the doors; when inactive, provides ground to the door lock actuators.
^ Courtesy Lights B+ Output: Supplies voltage to the courtesy lights, providing an inadvertent load (battery rundown) protection.
^ Driver Door Unlock: Supplies ground to the door lock relay, which provides power to the driver door actuator, and unlocks the driver's door lock.
^ DRL Link: Provides an interface to the DRL control module allowing the BCM to determine the current ambient light operating mode, and to activate the vehicle headlamps for alarm.
^ Fog Lamp Enable Control: Sends a ground signal to the fog lamp switch when the ignition switch on; this action enables the tog lamp switch. The tog lamps turn on when the tog lamp switch is enabled by the BCM.
^ Horn: Sends a ground signal to the horn relay, sounding the horn for the keyless entry alarm function.
^ Passlock Sensor Power: Provides B+ for Passlock sensor operation.
^ Passlock Sensor Ground: Provides ground to the Passlock sensor.
^ Passenger Door Unlock: When active, supplies voltage to the door lock actuators and unlocks the doors (except the driver's door); when inactive, provides ground to the door lock actuators.
^ RFA Link: Provides an interface allowing the transfer of keyless entry information to the Remote Control Door Lock Receiver (RCDLR).
^ Serial Data: provides an interface with the PCM, EBTCM, and the instrument cluster through the Class II serial data link.
^ Theater Dimming 1: Supplies ground to activate the I/P and door courtesy lamps.
^ Theater Dimming 2: Supplies ground to activate the dome and the roof rail courtesy/reading lamps.
