Steering Angle Sensor: Description and Operation
1. Control module for the steering wheel angle sensor
2. Steering wheel angle sensor
3. Reference groove
4. Encoder for steering movements.
Only cars equipped with DSTC (dynamic stability and traction control) have a steering wheel angle sensor control module. The easiest way to determine
if a car is equipped with DSTC (Dynamic stability and traction control) is to search for a switch, marked DSTC, positioned in the panel on the climate
The Steering wheel Angle Sensor Module is positioned on the side of the central electronic module. The only function of the steering wheel angle sensor
is to process the signals from the steering wheel angle sensor. The signals used by the DSTC system. The steering wheel angle sensor is mounted on the
steering wheel module and is directly connected to the steering angle sensor via a connector on the steering wheel module. The Steering wheel angle
sensor control module transmits signal information via the high-speed side of the Controller area network (CAN) to the brake control module, model
year 2002- or the ABS control module, model year 1999-2001.
If a fault occurs the control module for the steering angle sensor detects this and a diagnostic trouble code (DTC) is stored at the same time as the DSTC
function is switched off.
Diagnostic trouble codes (DTCs) stored in the control module for the steering wheel angle sensor. This information can be read off using the diagnostic
tool via the data link connector (DLC) in the car.
