Yaw Rate And Lateral Acceleration Sensor

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.

The yaw rate and lateral acceleration sensor is mounted on the transmission tunnel, forward of the gear selector module. The sensor is secured by 2 screws and connects to the vehicle wiring via a 4 pin multiplug.

When the ignition is ON, the sensor receives a power feed from the CJB (central junction box). The ground path for the sensor is located on the instrument panel cross-car beam. The sensor measures the yaw rate and lateral acceleration of the vehicle, providing values to the ABS module via a dedicated, private high speed CAN bus connection. The ABS module broadcasts these values on the high speed CAN bus for use by other systems.

If a sensor fault is detected by the ABS module, 'DSC NOT AVAILABLE' will be displayed in the instrument cluster message center and the amber warning indicator will illuminate.
