Traction Control

WARNING: This page is about a different car, the 2012 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

When the drive wheels lose traction and begin to spin, with vehicle speed under 108 km/h (67 mph), the ABS module commands the hydraulic pump motor on and the HCU to open and close the appropriate solenoid valves to modulate the brake pressure to the brake caliper(s), and may simultaneously send a request to the PCM over the High Speed Controller Area Network (HS-CAN) to reduce engine torque to maintain vehicle traction. The PCM accomplishes this with incremental timing changes and fewer fuel injector pulses until the ABS module ends the request. The request ends when the driven wheel speed returns to the desired speed. After the vehicle speed exceeds 108 km/h (67 mph), traction control is accomplished using only the PCM torque control function. The traction control system can be deactivated by pressing the traction control switch in the instrument panel.
