0xD91000 Wheel Speed Sensor Wheel 1-Data Valid But Above Normal Operational Range - Most Severe Level
Action: Check if tire size of all tires is according vehicle specification. Check C3 Signal calibration, check tachograp for additional faultcodes. Check number of teeth on tone wheel on all wheels.
What you'll see
Symptom:
System reaction
SystemReaction: ABS restricted. ESP control off. ATC off. DTC off. Diff-lock maybe restricted. HSA off. Trailer Brake off. Wheel Brake Monitoring off. ABS Warning Lamp.
Diagnostic depth
Detection: The deviation between the learned wheel circumferences and the EOL programmed values are too large (deviation > 25%).
Cause: Tyre with wrong circumference is mounted on one of the axels, wrong calibration of C3 -signal, tachograph not calibrated, wrong parameter for wheel cirumference, number of teeth of tone wheel.
