Traction Control System (TCS)

The stability assist recognizes critical driving conditions, and stabilizes the vehicle by individually braking each wheel and performing engine control intervention, without the need to actuate the brake or accelerator pedal.

The stability assist provides a further function known as Electronic Stability Program (ESP) to the ABS, Traction Control System (TCS) and the Electronic Brake Distribution (EBD). Whereas the ABS/TCS function controls wheel slip during braking and acceleration (longitudinal dynamics), the active yaw control stabilizes the vehicle about its vertical axis.

Sensors measure steering wheel position, brake master cylinder pressure, yaw rate and lateral acceleration. This makes it possible to compare driver's intention with momentary vehicle behavior so that in the event of the vehicle becoming unstable, the stability assist system can initiate the appropriate corrective action.

The stability assist module is self-monitoring. When ignition switch is turned to RUN position, the module will perform a preliminary electrical check, and at approximately 12 MPH, the pump motor is turned on for approximately 1/2 second. Any malfunction of the stability assist system will cause the stability assist system to shut off, the ABS indicator to illuminate and the power assist braking system to function normally.
