Circuit/System Description

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) applies a ground through the brake pedal position sensor (BPPS) low reference circuit to the BPPS. The BCM supplies a 5-volt reference through the brake sensor reference voltage circuit to the BPPS. When the brake pedal is being applied, the BPPS then sends a variable voltage through the brake sensor signal circuit to the BCM. The BCM then applies a signal to the brake signal circuit to the engine control module (ECM) and transmission control module (TCM).
