Inspect the BSI radar unit aiming in these instances:
After replacing or removing and reinstalling one or both of the BSI radar units.
After repairing the body panel(s) where the BSI radar unit(s) mount.
For any of the following aiming axis DTCs:
B18B8: Left Side BSI Radar Unit Azimuth Off Alignment
B1E68: Right Side BSI Radar Unit Azimuth Off Alignment
Before Inspection:
Clean the surface of the BSI radar unit.
Make sure the vehicle does not have aftermarket suspension.
Make sure all the tires are the correct size, and set their pressures to the specifications shown on the doorjamb label.
Make sure the fuel tank is full.
Remove all cargo from the vehicle except the spare tire and tool kit.
Park the vehicle on level ground (within 1 degree) with at least
13.1 ft (4 m) of space on both sides and behind the vehicle. Do not do
this procedure with the vehicle on a lift or with the tires on steel
plates or rollers.
Make sure the steering wheel is pointed straight ahead, and do not turn it after parking the vehicle.
Shift the transmission into P, and apply the parking brake.
Remove the rear bumper.
Set the target (A) on the stand (B).
Set the target height by adjusting the rod to the same height as the dot (C) in the center of the BSI radar unit.
Hold the plumb line against the dot (A) on the radar unit, and
lower the plumb bob until it touches the floor. Mark the floor at that
point (B).
Place the rim frame (A) by the rear wheel on the side of the
vehicle you are aiming. Adjust the spacers (B, C) to fit
against the wheel rim to make the rim frame parallel with the wheel.
Assemble the two sections of the straightedge, then place the hole in
the end of the straightedge over the mark on the ground that you made
in step 4. Slide the rim frame rearward until the base of the rim frame
and the straightedge meet as shown.
NOTE:
Make sure the spacers are still touching the wheel rim.
Set the straightedge according to the arrow (A).
Place the target over the other end of the straightedge, and
align the hole (A) in the base of the target with the hole in the end of
the straightedge as shown.
Use a degree setting angle of 1 degree on the angle gauge (A).
With the appropriate degree setting on the angle gauge up, set
the angle gauge against the radar unit. Align the cutout in the angle
gauge with the dot (B) on the radar unit.
Turn on the laser pointer (A), and set it on the angle gauge so that the beam shines on the target (B).
caution
Do not aim the laser beam at anyone's eyes.
Check the point (A) where the laser beam hits the target (B):
If the laser beam is within the target, the BSI radar unit is aimed properly, go to step 12.
If the laser beam is out of the target range, check the BSI radar unit mounting area.
