Smart Cruise Control (SCC) Radar Sensor Alignment

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.

Information 

The SCC radar sensor alignment is required when:

• The SCC unit is reinstalled or replaced with a new one.
• The radar sensor or the surrounding parts are impacted by a collision.
• The sensor does not recognize a forward vehicle.
• The Steering Angle Sensor (SAS) is replaced or adjusted.

Radar sensor should be aligned in both vertical and lateral direction. Vertical alignment can performed by using the SST (0K964-3T000) and lateral alignment can be performed automatically by driving on a road.

1. Park the vehicle on a level ground.
2. Remove the front bumper.

   (Refer to Body - "FRONT BUMPER COVER ")

3. Check the vertical alignment of the radar sensor using the SST 0K964-3T000 (A).

   If the vertical alignment is out of the tolerance, turn the adjustment screw (B) until the alignment is within the tolerance.

   Tolerance:  ±1.25° or less

5. To perform the lateral alignment, connect the GDS with the engine started and select the "SCC Alignment".

   Information 

   Be sure to erase DTC before performing the lateral alignment.
