Circuit/System Description

The brake pedal position (BPP) sensor is an input to the instrument panel module (IPM). The IPM then sends a serial data message to the electronic brake control module (EBCM) and other electronic control modules. The BPP sensor is a potentiometer type sensor with a 5-volt reference circuit and a low reference circuit. The IPM supplies the 5-volt reference to the BPP.
