FIGURE 16 - VERTICAL ADJUSTMENT
If stationary object warning is enabled (see Figure
21), a digital inclinometer must be used for vertical
alignment. Also, for best results the sensor should be
aligned -0.5° to -0.7° downward. Vertical alignment
outside these bounds will result in increased false
warnings and possible driver complaints.
2. Remove the cover as shown previously in the "Cover
Removal" section.
3. Position the alignment tool over the sensor so that
it straddles the sensor. Attach the alignment tool
to the bracket / sensor assembly with its magnet
attachments. See Figures 13 and 14.
4. Verify that the vertical alignment bubble is centered
between the two lines as shown in Figure 15. If it is not,
follow the VERTICAL ADJUSTMENT PROCEDURE
described below to align the sensor. When using the
bubble level for vertical alignment, it is important that
the bubble be centered with equal space between
edges of the bubble and the reference lines. System
performance will be too degraded if the bubble touches
either reference line. See Figure 15.

VERTICAL ADJUSTMENT PROCEDURE

Tools needed: 7mm box wrench and Bendix
alignment tool.
NOTE: Complete these steps only if vertical adjustment
is necessary.
1. With the Bendix alignment tool still in place, loosen the
four Vertical Position Screws. DO NOT remove these
screws. See Figure 16.

2. Adjust the Vertical Adjustment Screw until the desired
alignment is reached. Turn the screw clockwise or
counterclockwise depending on the vertical direction
(up or down) needed. Clockwise aligns the sensor up
and counterclockwise moves the sensor down.
3. Re-tighten the four Vertical Position Screws to hold
desired alignment in place.
4. Continuously check vertical alignment with the bubble
level as adjustments are made.
5. Check vertical alignment one more time after tightening
the 4 vertical position screws. For proper bubble
position refer to Figure 15.

CHECK LATERAL ALIGNMENT

Tools needed: Bendix ® ACB alignment tool and a ruler or
tape measure.
1. Park vehicle on a fl at, level surface such as a garage
fl oor. The vertical alignment must be checked and
adjusted, if needed, before the lateral adjustment can
be made.
2. Remove the cover as shown previously in the COVER
REMOVAL section.
3. Position the Bendix
sensor so that it straddles the sensor. Attach the
alignment tool to the bracket / sensor assembly with
its magnet attachments. See Figures 13 and 14.
4. Turn the switch on the side of the lateral alignment
laser level to the "on" position and place it in its cradle,
making sure it is sitting level. Align the laser beam
between the reference lines on the Bendix alignment
tool left or right. See Figure 17.
