The steering wheel angle sensor detects the steering angle and the rate of change of the steering wheel angle. This data is transmitted via the high-speed CAN bus. (controller network) in place with the quality factor and are used by the ABS module (anti-lock braking system) for CBC and DSC control.
The steering angle sensor is attached to the steering column pivot bracket with three screws. The steering angle sensor pinion engages a plastic drive flange on the lower column shaft. Inside the steering angle sensor, the pinion engages a gear train containing magnets. An eight-pin electrical connector provides the interface between the vehicle wiring and the internal circuits of the steering angle sensor.
The steering angle sensor uses the magnetic resistivity effect to evaluate the direction of the magnetic fields to measure the angular position of the lower shaft and, accordingly, the steering angle. When the steering wheel is turned, the lower shaft of the steering column turns the pinion in the steering angle sensor, which drives the gear train and rotates the magnets on the pinions. The direction of the magnetic fields is constantly monitored by the steering angle sensor and converted into the steering angle and steering speed.
Whenever the following conditions are met together, the steering angle sensor performs a plausibility check:
- The car moves in a straight line.
- The speed of the car is 20-25 km/h.
- The transfer case is in high gear.
- The brake pedal is not pressed.
- ABS not active (anti-lock braking system), DSC and ETC.
The steering angle sensor uses wheel speed, yaw rate and lateral acceleration signals to determine straight-ahead driving. If all conditions are met simultaneously, the steering angle sensor checks the steering wheel angle, which should be 0±15°. If the steering wheel angle is outside the specified range during two consecutive checks, the steering angle sensor changes the quality factor to "not accurate as specified" for the remainder of the current ignition cycle and stores a fault code. At the beginning of each ignition cycle, the signal quality factor is set to "with specified accuracy".
The status of the steering angle sensor can be determined using T4.
When replacing the steering angle sensor, the new sensor must be calibrated using T4. Also, recalibration of the steering angle sensor is required whenever its position relative to the steering column is disturbed, as well as when the upper and lower parts of the steering column are disconnected.
