Module Alignment - NAFTA

This procedure must be performed in the following cases:

• Removing / installing the radar sensor
• Warning light indicated the failure of the radar sensor proximity
• Rear axle adjustments
• Replacing wheel rims or tires with a larger or smaller diameter component
• Removing / installing the front end.

Preparation Measure 

- The following steps must be performed before beginning the control and adjustment of the sensor / proximity radar:

• Check the inflation pressure of the tires and, if necessary, correct it.
• Make sure the steering wheel is centered.
• Check that there is at least 3 meters (10 feet) in front of the vehicle for space to setup the sensor.
• The floor can have an angle of maximum inclination of 3 ° downhill or an uphill maximum inclination of 1 °.

6. Use the chalk line to snap a line on both the left and right side of the vehicle along the marks made with the plumb bob in the previous step. Extend the line that is snapped at least 3 meters (10 feet) in front of the center of the front wheels. This will allow room to properly position the alignment tool.

17. Verify that the laser is still lined up with the front chalk line. Then make sure the bubble is still in the middle of the level with the tilt cam in the 0 degree position.
18. Turn off the laser and remove it from the mirror.
19. Use the scan tool to perform the alignment procedure.

THE SENSOR / RADAR PROXIMITY 

- The calibration procedure involves performing three measurements, each time changing the angle of the reflecting mirror. To adjust the angle, tilt the mirror forward and then turn the tilt cam to the desired position.

• POSITION 1: mirror forward (2 degrees forward)
• POSITION 2: mirror in the middle (0 degrees)
• POSITION 3: mirror back (2 degrees rearward)
