The RCM is located under the floor console. The RCM is secured by 3 nuts and connects to the vehicle wiring via a multi-pin connector.

When the ignition is on, the yaw rate Lateral acceleration sensor within the RCM receives a power supply from the Central Junction Box (CJB). The sensor measures the yaw rate, roll rate, longitudinal acceleration and lateral acceleration of the vehicle, providing values to the Anti-lock Brake System (ABS) control module via High Speed (HS) Controller Area Network (CAN) chassis bus connection.

If a sensor fault is detected by the ABS control module, a warning message will be displayed in the message center and the DSC warning indicator will illuminate.
