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: This output supplies voltage to the door lock actuators when the doors are commanded to lock. This output also supplies ground to all the door lock actuators when the doors are commanded to unlock.
^ Courtesy Lamps Switched Feed: Provides courtesy lamps with power.
^ Driver Door Unlock: This output supplies voltage to the driver door lock actuators when the doors are commanded to unlock. This output also supplies ground to the driver door lock actuator when the doors are commanded to lock.
^ DRL 5V Reference: Provides 5 volts to the ambient light sensor.
^ DRL Link: Provides ground to the Headlamp relay control circuit.
^ Fog Lamp Enable (Front Fog Lamp Relay): Sends a ground signal to the fog lamp switch when the ignition switch is on, this action enables the fog lamp switch. The fog lamps turn on when the fog lamp switch is enabled by the BCM.
^ Headlamp Relay Control (Headlamps): Provides ground to the Headlamp relay control circuit.
^ Horn Output: Sends a ground signal to the horn relay, sounding the horn for the keyless entry alarm function or the content theft system.
^ Park Lamp Relay Control (Park Lamps): Provides ground to the Park Lamp relay control circuit.
^ Passenger Door Unlock: This output supplies voltage to the door lock actuators (except the driver door lock actuator) when the doors are commanded to unlock. This output also supplies ground to all the door lock actuators (except the driver door lock actuator) when the doors are commanded to lock.
^ PASSLOCK Sensor Ground: Provides the PASSLOCK sensor with ground.
^ PASSLOCK Sensor Power Output: Provides the PASSLOCK sensor with power.
^ RAP Relay Control (RAP Output): Provides ground to the RAP relay control circuit.
^ RFA Link: Provides an interface allowing the transfer of keyless entry information to the Remote Control Door Lock Receiver (RCDLR).
^ Serial Data Class 2: Provides an interface with the PCM, EBCM, Heater A/C Control, SDM and the IPC through the Class 2 serial data link.
^ Theater Dimming 1 Control: Supplies ground to activate the interior lamps.
