Subsequent Work
WARNING:
Steering-angle sensor not calibrated or calibrated incorrectly
- Unexpected vehicle handling
- Steering - angle sensor does not function
- Malfunction in steering-angle-sensor
→ After working on wheel suspension parts, when replacing the steering-angle sensor, and after changing the wheel alignment values, calibrate the steering-angle sensor using the PIWIS Tester.
→ Keep the front wheels in straight-ahead position on the measuring platform during calibration.
→ For vehicles with electromechanical steering, also re-teach the electric steering lock settings.
If the previous wheel alignment values (on rear and/or front axle) were changed, the following subsequent work must be performed:
- Calibrate steering-angle sensor for PSM.
