through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 38,

through 10A fuse [No. 3, located in fuse block (J/B)]

to combination meter terminal 28.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 20, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 67 and

to combination meter terminals 21, 22 and 23

through grounds M57 and M61,

to IPDM E/R terminals 39 and 59

through grounds E15 and E24,
HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives an input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IPDM E/R via the CAN communication lines. The CPU located
in the IPDM E/R controls the headlamp low relay coil, which when energized, directs power

through 15A fuse (No. 41, located in IPDM E/R)

through IPDM E/R terminal 54

to daytime light relay 2 terminals 1 and 5 (energizing the relay),

through daytime light relay 2 terminal 3

to front combination lamp RH terminal 3, and

through 15A fuse (No. 40, located in IPDM E/R)

through IPDM E/R terminal 52

to front combination lamp LH terminal 3.
Ground is supplied

to front combination lamp LH terminal 2

through grounds E15 and E24,

to headlamp RH terminal 2 via

daytime light relay 1 terminals 3 and 4

through grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam/Flash-to-Pass Operation
With the lighting switch in 2ND position and high beam switch in the HIGH position, the BCM receives input
signal requesting the headlamp high beams to illuminate. The flash-to-pass feature can be used any time and
also sends a signal to the BCM. This input signal is communicated to the IPDM E/R and the combination
meter via the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relay
coil, which when energized, directs power

through 10A fuse (No. 34, located in IPDM E/R)

through IPDM E/R terminal 56

to front combination lamp RH terminal 1, and

through 10A fuse (No. 35, located in IPDM E/R)

through IPDM E/R terminal 55

to front combination lamp LH terminal 1.
Ground is supplied

to front combination lamp LH terminal 2

through grounds E15 and E24, and

Aiming AdjustmentEKS00HXJ
The front fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing
aiming adjustment, make sure of the following.

Keep all tires inflated to correct pressure.

Place vehicle on level surface.

Set that there is no-load in vehicle other than the driver (or equivalent weight placed in driver’s position).
Coolant, engine oil filled up to correct level and full fuel tank.
Adjust aiming in the vertical direction by turning the adjusting screw (A).
1. Set the distance (C) between the screen and the center of front
fog lamp lens (E) as shown.
2. Turn front fog lamps (1) to ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone (A) is as shown.
NOTE:
When performing adjustment, if necessary, cover the headlamps
and opposite front fog lamp.
Bulb ReplacementEKS00HXK
1. Turn lighting switch OFF.
2. Turn off the fender protector (front) to obtain work space
between the fender protector and fender.
3. Disconnect front fog lamp connector (1).
4. Turn bulb socket (2) counterclockwise unlock and remove it.
5. Remove bulb from its socket.

Combination Switch InspectionEKS00HYO
1. SYSTEM CHECK
Referring to table below, check which system malfunctioning switch belongs to.
>> Check the system to which the switch belongs, and GO TO 2.
2. SYSTEM CHECK
With CONSULT-II
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Connect CONSULT-II, and select “COMB SW” on “SELECT
TEST ITEM” screen.
2. Select “DATA MONITOR”.
3. Select “START”, and confirm that other switches in the system
operate normally.
Example: When turn signal LH is inoperative, confirm that
PASSING, HEAD LAMP 2 or FRONT FOG (if equipped) turn
ON-OFF normally.
Without CONSULT-II
Operating combination switch, and confirm that other switches in the system operate normally.
Example: When a turn signal switch is inoperative, confirm that FRONT WIPER LO or FRONT WIPER INT
turn ON-OFF normally.
Check results
Other switches in the system operate normally.>>Replace lighting switch or wiper switch.
Other switches in the system do not operate normally.>>GO TO 3.
