Calibration - Front Radar Sensor: Procedure

  1. Vehicles built after August 20, 2017: skip to step  8.
  2. Remove components for access to the radar sensor:
    Vehicle Build Date Steps
    Vehicles built between April 10, 2016 and August 20, 2017 Remove the front fascia assembly Fascia Assembly - Front (Remove And Install) .
    Vehicles built after August 20, 2017 Remove the front fascia assembly Fascia Assembly - Front (Remove And Install) .
    Remove the HEPA filter inlet duct Duct - HEPA Filter - Inlet (Remove And Replace) .
  3. Drive the vehicle on to an alignment rack.
    NOTE: DAS 1.0 and DAS 2.0 vehicles need vertical alignment before Service Drive Alignment. DAS 2.5 vehicles need a Service Drive Alignment, and then vertical and horizontal alignment.
  4. Clean the front of the radar sensor with water and a clean shop towel.
  5. If the vehicle was built through August 20, 2017, use the bubble tool to check vertical alignment. If the bubble is not centered between the lines on the long side of the bubble tool, adjust the vertical alignment screw until the bubble is centered:
    CAUTION: Inspect the bubble tool for damage. Do not perform this procedure with a damaged bubble tool.
    CAUTION: Excessive pressure might misalign the radar sensor. Do not apply excessive pressure to the radar sensor or bubble tool.

    Tip: Use a flashlight to make the bubble easier to see.

    Tip: Remove the adjustment tool while measuring with the bubble tool to avoid misalignment of the radar sensor.

    Vehicle Build Date Bubble Tool Position Vertical Alignment Location
    Vehicles built through April 10, 2016 Gently hold the short side of the bubble tool flat against the upper center portion of the radar sensor face. Make sure that the bubble tool is against the sensor gasket.

  6. Remove the vehicle from the alignment rack.
    WARNING: In the next steps, an assistant must operate the vehicle while you use Toolbox.
  7. Install the front fascia.
  8. Connect a laptop to the diagnostic port of the vehicle, and then use Toolbox 3 to locally connect to the vehicle. See Toolbox 3 - Connect And Disconnect .
  9. Unlock the vehicle gateway for diagnostic communication. See Gateway Unlock .
  10. Shift the vehicle into Park.
  11. Using Toolbox 3, select the Actions tab, and the select the appropriate ODIN routine for the vehicle:
    • If the vehicle was built through August 20, 2017, search for "BOSCH Service Drive Alignment", select the ODIN routine PROC_RADC_X_BOSCH-SERVICE-DRIVE-ALIGNMENT, click on the link of the routine, and then continue to step 12  .
    • If the vehicle was built after August 20, 2017:
      1. Search for "Plant-Mode", select the ODIN routine PROC_RADC_X_PLANT-MODE, click on the link of the routine, click Run  , and allow the routine to complete.
      2. Search for "Service Drive Alignment", select the ODIN routine PROC_RADC_X_CONTINENTAL-SERVICE-DRIVE-ALIGNMENT, click on the link of the routine, and then continue to the next step.
  12. Click Run, follow the onscreen instructions, and adjust the radar sensor alignment according to the instructions in Toolbox 3. Repeat this step until Toolbox determines that the radar sensor alignment does not need adjustment.
    WARNING: Perform the calibration procedure in a suitable location and comply with all local traffic safety laws.
    NOTE: If the test drive shows the vehicle to track poorly or pull to the side, or if steering is sloppy or off center, then perform a four wheel alignment check.
    NOTE: Vehicles built after August 20, 2017: Bring the alignment adjustment tool in the vehicle during the drive cycle.
    NOTE: The front fascia must be removed any time the radar needs to be adjusted. Make sure that the fascia is installed before performing the service drive.
