When scanning the vehicle with the LAUNCH X431 diagnostic tool, if the C106600 DTC appears, you need to perform the SAS (Steering Angle Sensor) calibration function. This article will use Foton Tunland as an example to explain how to perform the SAS calibration function.
The SAS (Steering Angle Sensor) calibration function needs to be performed when one of the following situations occurs:
1. The DTC “C106600: Steering angle sensor calibration error” appears in the ABS or ESP system, as shown in the figure below.
2. The SAS (Steering Angle Sensor) is replaced.
Note: When replacing the SAS (Steering Angle Sensor), the C106600 DTC will also appear.
Applicable devices: LAUNCH full range of comprehensive diagnostic tools.
Vehicle Module: Foton Pickup Tunland
[Attention]
1. The ignition switch is ON.
2. The vehicle must be parked on a level surface.
3. The vehicle is in a straight-ahead status, and the tires and steering wheel are straightened at the same time. (An experienced technician is required to determine, and if you are not sure, you can use four-wheel aligner).
4. After the calibration is successful, enter the ABS/ESP system to clear DTCs.
5. After the SAS (Steering Angle Sensor) calibration is completed, a test drive must be carried out by passing a 90° curve (left or right turn) at speeds of 10km/h, 20km/h, 30km/h, and 40km/h respectively, or changing lanes on an open road in a serpentine manner.
Operation process:
1. Choose FOTON > PICKUP > TUNLAND > System Selection > Anti-lock Brake System (ABS) > Bosch ESP (ESP9) > Read DTCs.
The following DTC is read out: “C106600, Steering angle sensor calibration error”.
At the same time, the ESP lamp on the instrument panel is steady on.
2. Choose FOTON > PICKUP > TUNLAND > System Selection > Anti-lock Brake System (ABS) > Bosch ESP (ESP9) > Special Functions > SAS Sensor Calibration.
3. Click [Yes] to calibrate. The steering wheel must remain in the center position.
4. The SAS sensor calibration is completed.
5. Choose FOTON > PICKUP > TUNLAND > System Selection > Anti-lock Brake System (ABS) > Bosch ESP (ESP9) > Special Functions > Clear DTCs.
After DTC clearing, the ESP lamp on the instrument panel goes out, indicating that the calibration is successful.
6. After the SAS calibration is completed, a test drive must be carried out by passing a 90° curve (left or right turn) at speeds of 10km/h, 20km/h, 30km/h, and 40km/h respectively, or changing lanes on an open road in a serpentine manner.
