Part Description: Adaptive Cruise Control Sensor
Issue 1) If you are replacing this part due to the cluster displaying “Clean Radar Sensor in
Description: Front of Vehicle” or DTC C1266 ACC Sensor Blinded, please verify that there is no
blockage in front of the sensor. Blockage can occur from mud, ice, snow, front end
damage, bracket damage, the sensor not attached to the bracket properly or an
aftermarket fascia installed. This fault can occur intermittently in muddy or icy/snowy
conditions and is considered normal operation. Under some circumstances, a
misaligned sensor can also cause the C1266 DTC, please complete an alignment
procedure. No replacement is required.~
2) If you are replacing this part due to the cluster displaying “ACC/FCW Unavailable
Service Required”, please check the DTC fault codes. This will indicate which
module needs to be serviced (TCM, PCM, ESP/ABS, etc). This fault is not due to
the ACC Sensor. No sensor replacement is required.~
3) If you have fault code DTC C125E ACC Sensor Adjustment Required, please
verify that the radar sensor is fully seated in the clips and there is no damage (if
clips are damaged on a 2013 or earlier vehicle, order P/N 68085813A$, otherwise
please replace the module), please verify there is no blockage to the sensor due to
mud, ice, snow, front end damage, bracket damage or the sensor not attached to
the bracket properly. Perform the Vertical Alignment and the Electronic Horizontal
Alignments procedure as stated in the service manual. Please note, if the horizontal
alignment procedure will not complete, check the vertical alignment and confirm that
the sensor is seated properly. Rerun the horizontal alignment procedure. No sensor
replacement is required. **Hints for running Horizontal Alignment procedure: A)
Verify speed is between 45 and 75 mph, B) verify the road is relatively straight with
signs, poles, guard rails, etc C) Do not tail a vehicle too closely this inhibits the
learning procedure D) Service drive procedure may take up to 20 miles if conditions
are not correct. Please check setting on WiTech tool to verify you are meeting all
the requirements.~
4) If you are replacing this part due to DTC C124C ACC Disabled Due to ESP,
please verify that if the brake controller was replaced or serviced that a static
initialization was run on the brake controller and all faults where cleared in both the
brake controller and the ACC module. No replacement is required.~
5) If you are replacing this part due to a loss of communication set in another
module (PCM, TCM, ESP/ABS) please verify that the sensor connector is fully
seated.~
