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°.
Hood Lock Control Cable Assembly - Installation. ENGINE HOOD / DOOR. Lexus IS250 IS220d GSE20 ALE20

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:

  • HINT:
If "LEFT SIDE: 1.0°" is displayed, the divergence is 1.0° in the left direction. Turn screw B approximately 3 turns to the negative (-) side.
If the value does not change to 0°, it is possible that the sensor is aiming at something different. Reconfirm that there are no reflective materials in the surrounding area.

16. VEHICLE PREPARATION FOR FOG LIGHT AIM

Prepare the vehicle:

Ensure there is no damage or deformation to the body around the fog lights.
Fill the fuel tank.
Make sure that the oil is filled to the specified level.
Make sure that the coolant is filled to the specified level.
Inflate the tires to the appropriate pressure.
Place the spare tire, tools, and jack in their original positions.
Unload the trunk.
Sit a person of average weight (75 kg, 165 lb) in the driver's seat.
17. PREPARATION FOR FOG LIGHT AIMING
Hood Lock Control Cable Assembly - Installation. ENGINE HOOD / DOOR. Lexus IS250 IS220d GSE20 ALE20

Prepare the vehicle according to the following conditions:

Place the vehicle in a location that is dark enough to clearly observe the cutoff line. The cutoff line is a distinct line, below which light from the fog lights can be observed and above which it cannot.
Place the vehicle at a 90° angle to the wall.
Create a 25m (82 ft) distance between the vehicle (fog light bulb center) and the wall.
Place the vehicle on a level surface.
Bounce the vehicle up and down to settle the suspension.
  • 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.

Hood Lock Control Cable Assembly - Installation. ENGINE HOOD / DOOR. Lexus IS250 IS220d GSE20 ALE20

  • HINT:
Stand the screen perpendicular to the ground.
Align the V line on the screen with the center of the vehicle.
Hood Lock Control Cable Assembly - Installation. ENGINE HOOD / DOOR. Lexus IS250 IS220d GSE20 ALE20

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.

18. 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.

19. FOG LIGHT AIMING ADJUSTMENT
Hood Lock Control Cable Assembly - Installation. ENGINE HOOD / DOOR. Lexus IS250 IS220d GSE20 ALE20

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.
