Brake Lamps
WARNING: This page is about a different variant/trim than selected.
The brake (or stop) lamps and the Center High Mounted Stop Lamp (CHMSL) each have a path to ground at all times through a takeout and eyelet terminal of the body wire harness that is secured by a screw to the body sheet metal. The BCM receives a battery voltage input whenever the brake lamp switch is closed by the brake pedal arm. The BCM then energizes a high side driver, which provides battery voltage to the brake lamps and the CHMSL through a tail/stop lamp rear feed circuits.
