Rear Stop/Tail Lamps
The stop lamp uses a bulb and is activated when the ignition is on (power mode 6) or above and the brake pedal switch is active (by depressing the brake pedal). The HMSL will also be activated when the brake pedal is pressed. The stop lamps can also be activated by the ABS when All Road Progress Control (ARPC) is active (if equipped). The ABS module sends a HS CAN powertrain systems bus message to the BCM/GWM assembly which supplies power to the stop lamps and HMSL.
The side lamps are operated by selecting side lamps or headlamps on the left steering column multifunction switch. The side lamps can be switched on at all times and are not dependent on power mode. The side lamps will also be illuminated when the lighting control switch is in the 'AUTO' position and a 'lights on' signal is received by the BCM/GWM assembly from the rain/light sensor.
