DTC C1753: ACC/FCM Radar Blockage Detected: Notes
CAUTION:
- If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be set. Prior to this diagnosis, diagnose the CAN bus lines.
- Whenever the ECU is replaced, ensure that the CAN bus lines are normal.
NOTE:
The radar may not function normally if foreign object or dirt (snow or ice) is adhered on the radar or its surrounding area, or the road condition is bad due to a severe weather (heavy rain or snow). In that case, the system will deactivate the ACC and/or FCM as system protection and display an alert message ("ACC or FCM temporarily not available") on the combination meter.
