Advanced Smart Cruise Control (ASCC) Radar Sensor Alignment: Notes
Advanced Smart Cruise Control (ASCC) unit detects a vehicle in front and then calculates the distance to the vehicle in front and the relative speed by 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. For this reason, the radar sensor alignment procedure must be carried out whenever the sensor has been reinstalled or replaced with a new one.
If the sensor alignment procedure is not performed in the conditions mentioned above, the smart cruise control system may not operate correctly.
NOTE:
The ASCC radar sensor alignment is required when:
- The ASCC 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 ASCC unit is clean.
