Circuit Description
WARNING: This page is about a different car, the 2007 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
The electronic brake control module (EBCM) uses the brake pedal position sensor (BPP) Sensor to determine if an extended brake travel event has occurred. If an extended brake travel condition exists, the EBCM will provide a 5-volt output via the extended brake travel circuit to the engine control module (ECM).
