ABS With Traction Control, Electronic Stability Control (ESC) and Roll Stability Control (RSC®): Notes

The ABS with traction control, Electronic Stability Control (ESC) and Roll Stability Control (RSC®) consists of the following components:

• ABS module - attached to the Hydraulic Control Unit (HCU), but can be serviced separately.
• Front wheel speed sensors - one sensor is located in each front wheel knuckle. The sensors are serviced separately from the knuckle.
• Front wheel speed sensor tone rings - one tone ring is located in each wheel bearing and wheel hub assembly and is serviced with the wheel bearing and wheel hub.
• HCU - which contains several valves (inlet, outlet, isolation and dump), the hydraulic pump motor and is mounted behind the battery and battery tray.
• Rear wheel speed sensors - one sensor is located in each rear wheel knuckle, the sensors are serviced separately from the knuckle.
• Rear wheel speed sensor tone rings - one tone ring is located in each wheel bearing and wheel hub assembly and is serviced with the wheel bearing and wheel hub.
• Stability control sensor cluster - located under the rear of the front floor console and contains several sensors (yaw rate, roll rate, lateral accelerometer and longitudinal accelerometer).
• Steering wheel rotation sensor - located on the RH side of the clock spring and is serviced separately from the clock spring assembly.
• Stability/traction control switch - located in the instrument panel finish panel and is serviced separately from the finish panel.
