Description and Operation

WARNING:
WARNING:Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with the eyes. Wash hands thoroughly after handling. If brake fluid contacts the eyes, flush the eyes for 15 minutes with cold running water. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately. Failure to follow these instructions may result in personal injury.

The anti-lock control - anti-wheelspin control is an expanded version of the anti-lock brake system. The system is integrated with the anti-lock brake system and uses the same wheel speed sensors and similar hydraulic control unit.

The hydraulic control unit has additional internal solenoid valves incorporated to enable control modulation of the wheel brake pressures.

The system works by transferring torque from the spinning wheel(s) to the wheel(s) with the most traction. This torque transfer is achieved by the hydraulic control unit applying the relevant brake(s).

The system is only active at road speeds up to 85 km/h (53 mph). When the system is active the driver is made aware of the fact by the illumination of a warning indicator located in the instrument cluster.

Anti-wheelspin control, after a road speed of 85 km/h (53 mph) is controlled by a combination of fuel and spark adjustment using the vehicle engine management system. 2.0L - For additional information, refer to Section  303-14A Electronic Engine Controls / 303-14B Electronic Engine Controls. 2.5L - For additional information, refer to Section  303-14A Electronic Engine Controls / 303-14B Electronic Engine Controls.
