- CAUTION:
- Exposure to radio frequency emissions is hazardous to your health. It is hazardous to your health to be within 20 cm (7.9 in.) of the device's radio frequency aperture.
- NOTICE:
Before adjusting the radar beam axis, prepare the vehicle as follows:
Check the tire pressure and adjust it if necessary.
Remove all excess weight from the vehicle (luggage, heavy objects, etc. ).
Check and adjust the vertical direction of the radar sensor.
Remove dust, oil, and foreign matter from the radar sensor's level rack.
Set a level on the radar sensor's level rack.
Check that the air bubble is within the red frame on the level.
- OK:
- The air bubble is within the red frame on the level.
If the bubble is not within the red frame, use a hexagon wrench to adjust screw A until the air bubble is within the red frame.
- HINT:
- Result:
Adjustment Direction Adjustment Procedure Adjustment Angle Vertical adjustment Upward direction: Turn screw A to negative (-) sideDownward direction: Turn screw A to positive (+) sideApprox. 1.0° per turn
Adjust the reflector height.
Adjust the reflector so that the center of the SST reflector is the same height as the millimeter wave radar sensor.
- SST
- 09870-60000(09870-60010,09870-60040)
- HINT:
- Prepare a 10 m (32.81 ft) string, a string with a sharp-pointed weight (plumb bob), and a 5 m (16.41 ft) tape measure.
Place the reflector.
Hang the string (with weight) from the center of the vehicle's rear emblem. Mark the vehicle's rear center point on the ground. Repeat the same procedure for the front of the vehicle.
Set one end of the 10 m (32.82 ft) string on the vehicle's rear center point. Run the string over the vehicle's front center point to a position 5 m (16.41 ft) beyond the vehicle front center point, as shown in the illustration. Mark the 5 m (16.41 ft) position.
Using a tape measure, measure 12 mm (0.47 in.) to the left of the 5 m (16.41 ft) position. Place the reflector at that position.
- NOTICE:
- Perform the operation as precisely as possible.
Adjust the radar beam axis.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
Turn the intelligent tester main switch on, and turn the cruise control main switch on.
- HINT:
- If an error message is displayed on the screen, initialization of the distance control ECU may not be completed. Initialize the distance control ECU
Check and adjust the horizontal direction of the radar sensor.
Check that the divergence of the radar beam axis is 0° .
- Standard:
- 0° (Both right and left)
- If the axis is not as specified, use a hexagon wrench to adjust screw B until the divergence of the radar beam axis is 0°.
Based on the measured divergence of the beam axis, turn and adjust screw B for horizontal adjustment of the millimeter wave radar sensor using a hexagon wrench.
- Result:
Adjustment Direction Adjustment Procedure Adjustment Angle Horizontal adjustment Right direction: Turn screw B to positive (+) side.Left direction: Turn screw B to negative (-) side.Approx. 0.33° per turn
- HINT:
Reset the radar sensor's driving learning values. Prepare a type of metal that can block radio waves, such as aluminum foil. Cover the radar sensor's left half with the aluminum foil for 10 seconds.
- NOTICE:
- Be sure to keep the reflector in place and make sure that there is nothing between the sensor's left half and the reflector.
- HINT:
- When the reset is completed, the buzzer sounds for 10 seconds.
Disconnect the intelligent tester from the DLC3.
Recheck and readjust the vertical direction of the radar sensor.
Set a level on the radar sensor's level rack.
Check that the air bubble is within the red frame on the level.
- OK:
- The air bubble is within the red frame on the level.
- If the bubble is not within the red frame, use a hexagon wrench to adjust screw A until the air bubble is within the red frame.
- HINT:
- Result:
Adjustment Direction Adjustment Procedure Adjustment Angle Vertical adjustment Upward direction: Turn screw A to negative (-) sideDownward direction: Turn screw A to positive (+) sideApprox. 1.0°per turn
| 8. VEHICLE PREPARATION FOR FOG LIGHT AIM |
Prepare the vehicle:
| 9. PREPARATION FOR FOG LIGHT |
Prepare the vehicle according to the following conditions:
- NOTICE:
- A distance of 25 m (82 ft) between the vehicle (fog light bulb center) and the wall is necessary for proper aim adjustment. If unavailable, secure a distance of exactly 3 m (9.84 ft) for check and adjustment. (The target zone will change with the distance, so follow the instructions in the illustration.)
Prepare a piece of thick white paper (approximately 2 m (6.6 ft) (height) x 4 m (13.1 ft) (width)) to use as a screen.
Draw a vertical line down the center of screen (V line).
Set the screen as shown in the illustration.
- HINT:
Draw base lines (H line, V LH, V RH lines) on the screen as shown in the illustration.
- HINT:
- Mark the fog light bulb center marks on the screen. If the center mark cannot be observed on the fog light, use the center of the fog light bulb or the manufacturer's name marked on the fog light as the center mark.
H Line (Fog light height):
Draw a horizontal line across the screen so that it passes through the center marks. The H line should be at the same height as the fog light bulb center marks of the low-beam fog lights.
V LH Line, V RH Line (Center mark position of left-hand (LH) and right-hand (RH) fog lights):
Draw two vertical lines so that they intersect the H line at each center mark.
| 10. FOG LIGHT AIMING INSPECTION |
Cover the fog light or disconnect the connector of the fog light on the opposite side to prevent light from the fog light not being inspected from affecting fog light aiming inspection.
Start the engine.
Turn on the fog light and make sure that the cutoff line falls within the specified area, as shown in the illustration.
| 11. FOG LIGHT AIMING ADJUSTMENT |
Adjust the fog light aim into the specified range by turning the aiming screw with a screwdriver.
- NOTICE:
- The final turn of the aiming screw should be made in the clockwise direction. If the screw is tightened excessively, loosen it and then retighten it, so that the final turn of the screw is in the clockwise direction.
