Under normal circumstances, after repair in an accident, calibration of the relevant auxiliary systems need to be performed. When disassembling or reinstalling monitoring components such as cameras, radars, and sensors, replacing the vehicle ECU, or the vehicle height has been changed, auxiliary and other systems need to be calibrated.

For example: ACC calibration needs to be performed in the following cases.

1. Repair or replace the Adaptive Cruise Control (ACC) radar sensor control unit

2. ACC radar sensor deviation angle out of normal range

3. Adjust position of the ACC radar sensor on the vehicle body

4. Repair or replace bumper or radiator grill

5. Adjust chassis
