Repair Procedures: Inspection

Inspection procedures for smart cruise control system failure:

1. Check the bumper appearance and accident history (visual appearance of the vehicle, maintenance and bumper replacement history).

   → If the vehicle has been crashed, SCC mounting part is highly likely to be twisted.

2. Check whether the radar sensor cover of the bumper is dirty.

   → If the cover is dirty, SCC is highly likely to be released by the foreign substance during operation.

3. After starting engine, check SCC warning message on the cluster and DTC code. (Refer to DTC INDEX .)
4. After starting engine, stop for more than 5 seconds.

   → If system initialization (yaw rate sensor offset compensation) is not completed, SCC will not operate.
