Module Alignment - EMEA

SPECIAL TOOLS REQUIRED -

• 2021200000  - Reflective Mirror Support
• 2021201000  - Sealing Strip

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.

Fit the strap to the workshop floor:

• It is advisable to place the strip parallel to a perimeter wall of the workshop and at a safe distance to allow the operator to maneuver the equipment.
• The floor can have an angle of maximum inclination of 3 ° downhill or an uphill maximum inclination of 1 °.
• Unevenness maxims:
  • surface adjustment control unit: 1 mm
  • vehicle control surface: 10 mm.

Determining the axis of travel -  For the control and regulation of the sensor / proximity radar the mirror must be adjusted in horizontal and vertical position relative to the axis of travel of the vehicle. Normally, the vehicle is not located in a position exactly perpendicular to the control and also the measuring site may present surface irregularities and / or a slope. This must be done for the left and right side of the vehicle.

On the basis of the determined values of both sides of the vehicle, the diagnosis system then calculates the adjustments of the mirror for the alignment of the axis of travel.

Preparation Measure - 

Before beginning the control and adjustment of the sensor / proximity radar must perform the following steps:

• check the inflation pressure of the tires and, if necessary, correct it
• place the vehicle on the measuring site so that it is possibly orthogonal to the strip on the floor. If the deviation of the axis of travel of the vehicle with respect to the strip is greater than 5 °, it is not possible to base alignment
• check that the distance between the sensor / radar proximity and the reflex mirror is 120 cm +/- 5 cm.

6. Remove the mask, so that the laser beam on the mirror aligns with the strip.
7. The laser beam reflection of the mirror has to hit the bull's-eye mounted on the source of the laser beam.

8. To achieve this goal you have to adjust the horizontal / vertical position of the reflecting mirror in the following manner.
   • Horizontal adjustment:  by moving the graduated plate (a) and locking knob (b).

9. After adjustment of the mirror so that the laser beam is reflected on the target correctly, proceed to the relief portion of the horizontal and vertical through the graduated scales shown below.
   • Relief horizontal dimension

   • Significant vertical dimension
10. Proceed similarly to the right side to make the relief of the horizontal and vertical portion of the left side.

MIRROR ADJUSTMENT  - Perform the arithmetic average of the horizontal and vertical dimensions on the detected right and left side during alignment of the tool adjustment.

The mean value obtained from H horizontal dimensions and the value obtained by V vertical dimensions, should be used to set the final position of the reflecting mirror.

ADJUSTING THE SENSOR / RADAR PROXIMITY  - Connect the diagnostic tool to the control unit integrated in the sensor / proximity radar and launch the procedure "active misalignment calibration radar".

The calibration procedure involves performing three measurements each time changing the angle of the reflecting mirror. Acting on the tilting device of the reflecting mirror you get the required positions.

• POSITION 1: mirror forward
• POSITION 2: mirror in the middle (see Fig 12 )
• POSITION 3: mirror back
