Module Programming

Blind Spot Module (BSM) calibration procedure is required when the BSM, BSM bracket or the rear fascia is replaced

Equipment:

• Special Tool - (special tool #2042400080, Simulator, Rear Radar Doppler)
• Diagnostic Scan Tool
• Plumb Bob
• Marking Device (tape, grease pen or similar tools)
• Measuring Devices (measuring tape and an angle ruler L square or similar tools)

The BSM calibration must be carried out only after the following items have been completed:

• Check and adjust the tire inflation pressure to the specified values.
• Confirm that the vehicle meets the following load conditions:
  1. unloaded
  2. mostly empty fuel tank
• The vehicle must be clean of any debris or contaminants in the rear bumper area. This can obstruct communication between the BSM, Rear Radar Doppler Simulator 2042400080 and the diagnostic scan tool used to perform this programming procedure.
• The vehicle and the Rear Radar Doppler Simulator 2042400080 must be on a flat level surface or the calibration procedure will not properly complete.
• Clear the area of metal objects and personnel as this can cause interferences with the Rear Radar Doppler Simulator 2042400080. Make sure that coworkers do not walk through the area while performing the calibration procedure.
• Use the diagnostic scan tool to correct or clear any Diagnostic Trouble Codes (DTC's).

2. Use the plumb bob to make another center line mark at the rear of the vehicle using the center of the Center High Mounted Stop Lamp (CHMSL) (1a) as a reference and label this mark B.

3. Run a straight line (1a) through point A at the front of the car through point B at the rear of the car and continue past the rear bumper and mark that spot as C. Spot C must be 6.70 to 6.74 meters (21-22 ft.) from the front of the front bumper.

4. Measure to the right of point C 67.0-67.4 centimeters (26.3-26.5 inches). This must be at a right angle to the center line and mark it as point D.
5. Measure to the left of point C 67.0-67.4 centimeters (26.3-26.5 inches). This must be at a right angle to the center line and mark it point E.

6. Place the (special tool #2042400080, Simulator, Rear Radar Doppler) (1a) on spot E. Plug it in and turn it on. Confirm the tool is turned on by verifying that the green power light is illuminated.
7. Adjust the Rear Radar Doppler Simulator special tool 2042400080 so that the top of the head (3b) is 64-66 cm. (25-26 in.) from the floor (2). Take caution to not drop the head when you loosen the knob at the rear. 
8. Level out the Rear Radar Doppler Simulator special tool 2042400080 by adjusting the feet (3a) until the level gauge shows level.
9. Ensure that the Rear Radar Doppler Simulator special tool 2042400080 is parallel to a line that runs through spot D, C, and E.
10. Using a scan tool, navigate to the "BSM Blind Spot Module" and select the "Misc Functions" menu.
11. Select and run the "BSM Radar Aiming" procedure and follow the steps to complete the left side calibration.
12. After the left side calibration is complete, reposition the Rear Radar Doppler Simulator special tool 2042400080 on point D and run the procedure again to calibrate the right side.
13. Once the diagnostic scan tool reads that the calibration was successful, the procedure is complete.
