Anti-Lock Brake System & Traction Control System: Description

The Bosch 2U Anti-Lock Brake System (ABS) with Traction Control System (TCS) increases vehicle steerability, directional stability and optimum deceleration in severe braking conditions on most road surfaces. The ABS monitors wheel speed and controls brakeline pressure to eliminate uncontrolled skidding.

The system also monitors rear wheel speed and compares it to front wheel speed. If excessive front wheel speed is detected at either front wheel, the TCS will be activated. TCS uses front brake intervention and cylinder cut-out to provide improved traction and vehicle stability. Models with 4.6L Northstar are equipped with ABS and real-time TCS. Models with 4.9L may be equipped with only ABS or ABS with timed cylinder cut-out TCS.

ABS consists of Electronic Brake Control Module (EBCM) or Electronic Brake and Traction Control Module (EBTCM), Brake Pressure Modulator (BPM) valve, solenoid valves, pump motor, ABS valve relay, pump relay and speed sensors on front and rear wheels, brake booster/master cylinder assembly, BRAKE and ANTI-LOCK warning indicator lights and Driver Information Center (DIC).
