ABS Description and Operation: Notes

WARNING: This page is about a different car, the 2005 GMC Canyon and 2005 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.

This vehicle is equipped with an Advics electronic brake control module (EBCM) and brake pressure modulator valve (BPMV).

The following vehicle performance enhancement systems are provided.

Antilock Brake System (ABS)
Dynamic Rear Proportioning (DRP)
Traction Control System (TCS) (w/NW7)

The EBCM controls the system functions and detects faults. The EBCM contains six solenoids that are commanded ON and OFF by the EBCM to operate the appropriate valves in the brake pressure modulator valve (BPMV).

The BPMV uses a 3-circuit configuration to control hydraulic pressure to each front wheel independently, and to the rear wheels as a pair.
