Yaw Rate And Lateral Acceleration Sensor

The yaw rate and lateral acceleration sensor is located beneath the floor console and provides information of vehicle yaw rate and lateral acceleration to the ABS module. The sensor is internally damped to isolate it from body vibrations and is secured to the transmission tunnel with two bolts.

When the ignition is on, the yaw rate and lateral acceleration sensor receives a power feed from the CJB. Yaw rate and lateral acceleration values are transmitted to the ABS module on a private high speed CAN bus. In addition to using the inputs for brake control functions, the ABS module also broadcasts the yaw rate and lateral acceleration values on the vehicle high speed CAN bus for use by other systems.

The ABS module monitors the yaw rate and lateral acceleration sensor for faults and can be interrogated using Land Rover approved diagnostic equipment. If a fault is detected, the ABS module stores a related DTC and transmits a high speed CAN bus signal to the instrument cluster to illuminate the DSC, HDC and brake warning indicators. The instrument cluster will also sound a warning chime and display a DSC fault message in the message center.
