SYSTEM
The function of the Anti-Lock Brake System (ABS) is to minimize wheel lockup during heavy braking on most road surfaces. The system performs this function by monitoring wheel speed and controlling the brake fluid pressure to each front wheel and both rear wheels during braking. This allows the driver to retain directional stability and better steering capability.
SYSTEM COMPONENTS
Refer to Fig. for system component locations.
ELECTRONIC CONTROL UNIT (ECU)
The ECU located on the rear righthand side of the engine compartment uses various inputs to control ABS operation and provide ...
