Distance Sensor: Adjustments
Millimeter Wave Radar Unit Aiming
Special Tools Required
Radar aimer set 070AJ- SDA0100
Prepare the items shown:
-
HDS
-
Level (commercially available)
-
Tape measure and scale
-
String (about 33 ft (10 m) length)
-
String with a plumb bob
-
Ballpoint pen
-
Tape
NOTE: If the millimeter wave radar unit is removed or replaced, or if a millimeter wave radar unit aiming error occurs, aim the millimeter wave radar
unit. Incomplete aiming, an aiming error, or dust or dirt on the radar unit surface causes the adaptive cruise control (ACC) indicator to come on.
-
Millimeter wave radar unit aiming incomplete: DTC 107
-
Millimeter wave radar unit aiming error: DTC 63
-
Millimeter wave radar unit or emblem surface is contaminated with dust, dirt, ice, or snow: DTC 105
Before Aiming:
-
Aiming the millimeter wave radar unit requires the HDS.
-
Clean the surface of the millimeter wave radar unit.
-
Make sure the vehicle has no aftermarket suspension.
-
Make sure all the tire sizes are correct and that their pressure is correct.
-
Make sure the fuel tank is full.
-
Remove all baggage from the vehicle except the spare tire and the tool kit.
-
Make sure the steering wheel is straight ahead, and do not turn it after setting the vehicle.
-
Shift transmission lever into P, and apply the parking brake.
-
Make sure the upper grille and the front bumper are installed correctly.
-
Park the vehicle on level ground in a wide open space to avoid misadjusting caused by reflecting objects. The space needs to be 32.8 ft (10 m) in
front, 13.1 ft (4 m) in width and 4.9 ft (1.5 m) in height.
-
If NO TARGET is not indicated even when there are no objects for 33 ft (10 m) in front vehicle, check for reflecting objects in front of the
vehicle.
NOTE: When the millimeter wave radar unit is adjusted on ground that has more than 1 degrees of horizontal slope (drainage slope), the vertical
aiming cannot be adjusted correctly. Check the levelness of the ground, and adjust the angle of millimeter wave radar unit to be parallel to that of the
ground, lay a ruler (at least 12 inch) or other flat straight object on the ground and put the level on top to confirm the levelness of the ground.
Vertical Aiming
NOTE: When the millimeter wave radar unit is adjusted on ground that has more than 1 degrees of horizontal slope (drainage slope), the vertical
aiming cannot be adjusted correctly. Check the levelness of the ground, and adjust the angle of millimeter wave radar unit to be parallel to that of the
ground, lay a ruler (at least 12 inch) or other flat straight objects on the ground and put the level on top to confirm the levelness of the ground.
1. Remove the upper grill cover.
