lamp until the turn signal request is no longer active.

When the BCM receives input from the headlamp switch indicating a request for the rear fog lamp, the BCM provides voltage to the rear fog lamp.

The BCM also provides an Field Effect Transistor (FET) protection of the fog lamp output circuits. When an excessive current draw is detected, the BCM disables the fog lamp output circuit drivers.

BCM Network Input Messages

Broadcast Message	Originating Module	Message Purpose
Reverse gear state	PCM	Indicates the transmission selector is in reverse to the BCM. When the transmission selector is in REVERSE and the ignition is in RUN, the BCM provides voltage to the reversing lamps.

Reversing Lamps

When the transmission is in REVERSE, the PCM sends a message over the HS-CAN1 to the BCM indicating the transmission is in REVERSE. The BCM provides voltage to the reversing lamps when it receives the message that the transmission is in REVERSE and the ignition is in RUN.

The BCM also provides an Field Effect Transistor (FET) protection of the reversing lamps output circuit. When an excessive current draw is detected, the BCM disables the affected reversing lamps circuit driver.
