13. Press the "ENTER" key.
HINT:
*1: Either UPPER or LOWER is indicated.
*2: Either LEFT or RIGHT is indicated.
*3: Values between 0.0 and 6.3 are indicated.
The direction and angle that actually deviate from the spec are displayed in the multi-information
display on the combination meter when starting the optical axis adjustment mode with the hand-
held tester.
14. Move the reflector either to the right or left by 100 mm (3.937 in.) and check that the value
changes.

15. Return the reflector to the original position and read the current angle.

HINT:
When the values displayed on the screen are normal, the values are within the above range. If the
value is out of range, check the installation condition of the bumper reinforcement, etc.
16. Turn the headlamp dimmer switch to the TAIL position.
17. Press the "ENTER" key.

13. Confirm that the current distance (reference value) is approximately 5 m (16.41 ft).
HINT:
If the distance is 0 m, the sensor can not detect the target. Reconfirm that there is no metal in the
region.
*1: Either DISTANCE is indicated.
*2: Either LEFT or RIGHT is indicated.

g. Adjustment in horizontal direction
1. Read the divergence in the current angle.
Standard:
0° (Both right and left)
2. 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.
HINT:

If "LEFT SIDE: 0.6°" is displayed, the divergence is 0.6° in the left direction. Give the screw
approximately 3 turns to the positive (+) side.

1.GENERAL
The rear window defogger system's thin heater wires are attached to the inside of the rear window and
defog the window surface quickly. The indicator lamp illuminates while the system is operating. The
system automatically turns off after approximately 15 minutes.

DLC3 REFERENCE TABLE
HINT:
Connect the cable of the hand-held tester (with CAN VIM) to the DLC3, turn the ignition switch ON and
attempt to use the hand-held tester. If the screen displays the message UNABLE TO CONNECT TO
VEHICLE, there is a problem either with the vehicle or with the tester.
If communication is normal when the tester is connected to another vehicle, inspect the DLC3 on
the original vehicle.
If communication is still impossible when the tester is connected to another vehicle, the problem is
probabl
y in the tester itself. Consult the Service Department listed in the tester's instruction manual.

A/C control assy:
A/C CONTROL ASSY - REFERENCE TABLE
CIRCUIT DESCRIPTION
When the defogger switch is turned on, a rear defogger activation request signal is input to the A/C control (A/C
ECU) from the multi-display
1 or center cluster integration panel2 . Then, the A/C control assembly outputs this
signal to the defogger relay (Marking: DEFOG) and the rear window defogger system is activated.
