Steering Angle Sensor

The steering angle sensor is connected to the steering wheel with 2 dowels. The steering angle sensor monitors steering wheel rotation, and provides information of the steering wheel angle and rate of speed of steering wheel movements.

A code wheel and 16 optical digital sensors are installed inside the steering wheel angle sensor. Rotation of the code wheel is read by the optical-digital sensors to produce steering wheel rotational speed signals. The steering angle sensor is able to measure a rotation range of +/- 720 degrees, although the steering mechanism will only allow the steering wheel to rotate a maximum of +/-540 degrees.

Signals from the steering angle sensor are transmitted on the vehicle high speed CAN bus, and received and processed by other systems such as DSC. The transmitted information includes details of steering wheel angle and steering wheel rotational speed, along with signal integrity information.

If a fault occurs within the steering angle sensor, a DTC will be set and stored in the steering angle sensor memory. The steering angle sensor fault is also stored in the ABS module memory that illuminates the appropriate warning indicator lamps, depending on the system functions affected (DSC/ETC, ABS, EBA/EBD, HDC). A warning chime is also sounded to alert the driver to the fault condition.

For vehicles installed with a high-line instrument cluster, a message is displayed in the message center, only if the fault affects the HDC function.

The steering angle sensor and ABS module are able to be interrogated using the Land Rover approved diagnostic equipment.
