Traction Control System

TCS (ASR)

The primary function of the Traction Control System is to reduce wheel slip and maintain traction at the driven wheels when the road surfaces are slippery. The Traction Control System reduces wheel slip by applying the brake that has lost traction. The system is designed to operate at speeds below 50 km/h (30 mph). The engine's torque can be reduced by the ECM via the CAN C Bus, if necessary. The TCS can be deactivated with switch on the dash. The Traction Control System uses the ABS to indicate spinning tires to enable the traction control function. The TCS software is in the CAB.

The TCS (ASR) performs the following functions:
1. Engine power derate
2. Engine deceleration regulation. If the vehicle is on a patch of ice, the simple action of releasing the throttle is enough to cause the rear wheels to slip. To avoid this, the throttle input is regulated so power drops slowly instead of abruptly. The engine power is reduced (decelerated) as necessary.
