Cruise Control Module: Adjustments

ADAPTIVE CRUISE CONTROL (ACC) ALIGNMENT

The Adaptive cruise control alignment must be performed after replaced with a new unit or removal of unit servicing any other component, any front fascia replacement or removal and vehicle wheel alignment. The alignment procedure ensures that the field of vision for the Adaptive speed control unit imager is aimed at the proper path directly ahead of the vehicle.

VEHICLE PREPARATION FOR ADAPTIVE CRUISE CONTROL ALIGNMENT

1. Inspect vehicle for any damage that could affect ACC function or alignment, damaged suspension, wheel alignment, damaged fascia, broken grill.

2. Verify proper tire inflation pressures.

3. Verify that the vehicle is sitting level.

4. Be certain that the ACC lens is clean and free from obstructions.

5. Remove any accumulations of mud, snow or ice from the vehicle underbody.

6. Verify that there is no load in the vehicle (cargo or passengers).

7. Repair or replace any ineffective, worn or damaged suspension components that will hinder proper adaptive cruise control alignment.

8. Be certain that the assembly mounting screw are tightened to 9 Nm (79.5 in. lbs.).

9. The fuel tank should be FULL. Add 2.94 kilograms (6.5 pounds) of weight over the fuel tank for each estimated gallon of missing fuel.

10. Verify that the vehicle has at least 16 kilometers (10 miles) showing on the odometer.

11. Close and latch hood.

MARK CENTERLINE ON WINDSHIELD





12. Take a measurement (2) across the lower edge of the tint band at the top of the windshield on each side of the glass as the reference points.

13. Divide the upper measurement (2) in half and mark that dimension near the lower edge of the tint band on the glass using a grease pencil or equivalent. This is the upper centerline of the glass.

14. Take a measurement (1) across the upper edge of the blackout area at the base of the windshield using the inside corner where each side blackout area intersects the lower blackout area as the reference points.

15. Divide the lower measurement (1) in half and mark that dimension near the upper edge of the lower blackout area on the glass using a grease pencil or equivalent. This is the lower centerline of the glass.

16. Connect the top center mark and the lower center mark and mark a straight line (3) for the center of the glass.

MARK CENTERLINE ON REAR GLASS





17. Take a measurement across the upper edge (2) of the rear glass using the vertical edges of the body opening as the reference points.

18. Divide the upper measurement in half and mark that dimension on the glass using a grease pencil or equivalent. This is the upper centerline of the glass.

19. Take a measurement across the lower edge (1) of the glass using the vertical edges of the body opening as the reference points.

20. Divide the lower measurement in half and mark that dimension on the glass using a grease pencil or equivalent. This is the lower centerline of the glass.

21. Connect the top center mark and the lower center mark and mark a straight line (3) for the center of the glass.

SET UP AIM BOARD AND TRIPOD





NOTE: These step's are critical to the alignment of the ACC to the vehicle, make sure that you have the correct measurement and the aiming board is in the correct position.

22. Position the vehicle on a level/flat surface.

23. Place the aiming board (Special Tool No. 9965) and tripod (Special Tool No. 9649) 4 meters (157.5 inches) from the front of the ACC module and is 90 degrees to the front of the vehicle. Measure from the front of the ACC module grille area to the aiming board.

24. Sight through the V-notch in the upper edge of the aim board to align and center the board to the centerline marks on both the windshield and the rear glass.





25. Adjust the tripod so that the top edge of the aiming board is level at BOTH CORNERS to the following dimension:

- Rear Wheel Drive 884 millimeters (34 13/16) inches)
- All Wheel Drive 894 millimeters (35 3/16) inches)

CALIBRATION PROCEDURE





1. Turn the ignition switch to the ON position.

2. Connect a scan tool to the Data Link Connector (DLC) (1) below the driver side end of the instrument panel (2).

3. Obtain vehicle information, select ECU View from the Home Screen.

4. The Scan tool will then show a list of all ECU's available on the vehicle.

5. Select the ACC Adaptive Cruise Control from the ECU view screen.

6. The next screen ECU Overview window appears, select the MISC. Functions.

7. Select the Align ACC sensor and press Start.

8. Follow the scan tool instructions.





9. "This routine is used to align the ACC sensor. To properly align the system you must have the ACC sensor alignment board positioned properly. Improper setup of the ACC alignment board will affect ACC performance. Press "Next" to continue or "Cancel" to exit."





10. "Performing rough alignment. Ensure the vertical alignment cover is installed on the alignment board, this covers both of the alignment's on the aiming board. The horizontal adjustment screw is located on upper right corner of the ACC sensor. The vertical adjustment screw is located on the lower left corner of the ACC sensor."





11. After rough alignment mode is complete: "Remove the vertical alignment cover. Press "Next" to continue."

12. "Performing fine alignment. Ensure the vertical alignment cover is removed from the alignment board. The horizontal adjustment screw is located on upper right corner of the ACC sensor. The vertical adjustment screw is located on the lower left corner of the ACC sensor."

13. After fine alignment mode is complete: "Clearing internal compensation value."

14. Final step: "Internal compensation cleared. ACC sensor alignment complete. Press "Finish" to exit."

15. Remove grease pencil marks from windshield.
