Stoplamps
The BCM monitors the input from the stoplamp switch. When the brake pedal is applied, voltage is routed to the BCM, indicating a request for the stoplamps. The BCM then supplies voltage to the high mounted stop lamp assembly and sends a stoplamp request over the HS-CAN1 to the GWM. The GWM then sends this stoplamp request to the Body Control Module (BCMB) over the MS-CAN. When the Body Control Module (BCMB) receives this request, it supplies voltage to the rear lamp assemblies to illuminate the stoplamps.
The BCM does not activate the stoplamps when the ignition is OFF.
The BCM Body Control Module (BCMB) and also provide an Field Effect Transistor (FET) protection of the stoplamp output circuits. When an excessive current draw is detected, the BCM or Body Control Module (BCMB) disable the affected stoplamp circuit driver.
