LESSON 2: CHASSIS
Traction Control
Traction control on vehicles equipped with a four-channel system operates in the following manner:
•
At speeds under 100 km/h (62 mph), when a drive wheel looses traction, the stability assist module/ECU
signals the PCM to reduce engine torque, while simultaneously applying and releasing the appropriate brake
caliper(s) to maintain traction. The PCM reduces torque by changing ignition timing, reducing fuel injector
pulses or closing the throttle via the Electronic Throttle Body (ETB).
•
After the vehicle speed exceeds 100 km/h (62 mph), traction control is accomplished only through PCM torque
control
