Circuit/System Description

WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

The BCM controls the stop lamps based on the input from the Brake Pedal Position Sensor (BPPS). When the BCM detects the brake pedal is depressed, B+ is applied to the stop lamp switch signal circuit and both stop/turn lamp supply voltage circuits, illuminating the center high mount stop lamp (CHMSL) and both stop lamps.
