Smart Cruise Control (SCC) Sensor Alignment: Notes
Smart Cruise Control (SCC) unit detects a forward vehicle and then recognizes the distance to the forward vehicle and the relative speed using the built-in radar sensor. In order for the radar sensor to operate correctly, it must be properly aligned parallel to the driving direction of the vehicle. So, the radar sensor alignment procedure must be carried out after the sensor is reinstalled or replaced with new one. If not performing the sensor alignment in the conditions mentioned above, the smart cruise control system may not operate correctly.
NOTE:
The SCC radar sensor alignment is required when:
- The SCC unit has been reinstalled or replaced with a new one.
- The radar sensor or the surrounding parts have been impacted by collision.
- The sensor cannot detect a vehicle in front.
- The Steering Angle Sensor (SAS) has been replaced or adjusted.
CAUTION:
If the sensor cannot detect the vehicle in front:
- Park the vehicle on a level ground.
- Take out heavy luggage from the vehicles' seats or trunk.
- Set all tires according to the specified pressure.
- Check wheel alignment.
- Check that the front surface of the SCC unit is clean.
