Steering Angle Sensor

The steering angle sensor is mounted at the bottom of the steering column, in front of the flexible coupling. It utilizes two potentiometers to determine steering angle and the rate of steering change. These signals are processed in the steering angle sensor and a digital output signal is passed over the CAN bus to the DSC control module.

The sensor requires calibration after repairs to the steering or suspension system. The sensor is calibrated using the DIS or MoDiC. Once calibrated, the sensor sends an ID number to the DSC control module. The ID provides confirmation to the module that the angle sensor is properly calibrated.

Installing a new sensor or exchanging sensors with another vehicle will require that this calibration procedure is carried out.
