procedure.
YRS calibration error. Verify proper installation of the YRS. Verify proper wiring between the ECU and the YRS.
Check YRS output. Verify that correct YRS is being used. Verify proper ECU programming. Perform YRS calibration
procedure.
YRS calibration error. Verify proper installation of the YRS. Verify proper wiring between the ECU and the YRS.
Check YRS output. Verify that correct YRS is being used. Verify proper ECU programming. Perform YRS calibration
procedure.
ECU has detected an incorrect YRS signal. Verify proper installation of the YRS. Verify proper wiring between the
ECU and the YRS. Check YRS output. Verify that correct YRS is being used. Verify proper ECU programming.
Perform YRS calibration procedure.
ECU has detected an incorrect YRS signal. Verify proper installation of the YRS. Verify proper wiring between the
ECU and the YRS. Check YRS output. Verify that correct YRS is being used. Verify proper ECU programming.
Perform YRS calibration procedure.
ECU has detected an incorrect YRS signal. Verify proper installation of the YRS. Verify proper wiring between the
ECU and the YRS. Check YRS output. Verify that correct YRS is being used. Verify proper ECU programming.
Perform YRS calibration procedure.
ECU (if configured) must confirm that YRS and SAS signals match. The vehicle must be exposed to an S-shaped
driving maneuver for this DTC to automatically clear. If the DTC does not clear even after the S-shaped driving
maneuver, check and correct the orientation of the YRS and repeat maneuver.
