Inspection of Headlight Leveling Control Module and Its Circuit (Headlight Auto Leveling System)S6RW0D9204023
Headlight auto leveling control module and its circuits can be checked at headlight auto leveling control module wiring
couplers by measuring voltage and pulse signal.
CAUTION!
Headlight auto leveling control module cannot be checked by itself. It is strictly prohibited to connect
voltmeter or ohmmeter to headlight auto leveling control module with couplers disconnected from it.

Voltage Check
Check voltage between each terminal of headlight auto leveling control module and vehicle body ground under each
condition. If measured voltage is out of standard value, check circuit (including switch and sensor) of terminal where
voltage was measured.
NOTE
• As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when
ignition switch is ON.
• Voltage with asterisk (*) cannot be measured by voltmeter because it is pulse signal. Check it with
oscilloscope if necessary.

Front Fog Light Switch Inspection (If Equipped)S6RW0D9206016
NOTE
Front fog lights light up only when headlight
switch is in HEADLIGHT position (low or high
beams) or SMALL position. Front fog lights
turn OFF automatically when headlight
switch is turned to OFF position. If front fog
light switch holds ON position, front fog
lights turn ON automatically when headlight
switch is tuned to HEADLIGHT position (low
or high beams) or SMALL position again.

Check for continuity between terminals at each switch
position. If check result is not as specified, replace
switch.
Front Fog Light Aiming Adjustment with Screen
(If Equipped)
S6RW0D9206018
Basic Aiming
NOTE
• Unless otherwise obligated by local
regulations, adjust front fog light aiming
according to the following procedure.
• An example in case that the light-to-wall
distance 10 m is shown in the illustration.
The beam descending distance “H” is
calculated when “a” is 10 m with the
specification angle “b” (1.14°).

1) Make sure the following items.
• Place vehicle on a flat surface in front of blank wall
(screen) (1) ahead of front fog light surface.
Distance between screen and front fog light
“a”: 10 m (32.8 ft.)
• Adjust air pressure of all tired to the specified
value respectively.
• Bounce vehicle body up and down by hand to
stabilize suspension.
• Carry out aiming with a driver aboard.
