With the ignition switch in the ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

through 10A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38,

through 10A fuse [No. 14, located in fuse block (J/B)]

to combination meter terminal 8.
With the ignition switch in ACC or ON position, power is supplied

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

to BCM terminal 11.
Ground is supplied

to BCM terminal 52 and

to combination meter terminals 10, 11 and 12

through grounds M71 and M72,

to IPDM E/R terminals 38 and 60

through grounds E1 and E31.
LOW BEAM OPERATION
When the lighting switch is in 2ND position, BCM detects the HEAD LAMP1 and 2 (ON) by BCM combination
switch reading function. BCM sends low beam request signal (ON) through CAN communication.
When receiving low beam request signal (ON), IPDM E/R turns ON headlamp low relay in IPDM E/R. IPDM E/
R supplies power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 1,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 1.
Ground is supplied

to front combination lamp RH and LH terminals 5

through grounds E1 and E31.
With power and ground supplied, low beam headlamp illuminates.
HIGH BEAM OPERATION
When the lighting switch is in HIGH BEAM position and then also in 2ND position, BCM detects the HEAD
LAMP1, 2 (ON) and the HI BEAM (ON) by BCM combination switch reading function. BCM sends low beam
request signal (ON) and high beam request signal (ON) through CAN communication.
When receiving low beam request signal (ON) and high beam request signal (ON), IPDM E/R turns ON head-
lamp low relay and headlamp high relay in IPDM E/R. And then, headlamp bulbs go ON. High beam solenoids
move the bulb shades in the front combination lamps, and the bulb shades change to high beam position.
IPDM E/R supplies power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 1,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 1,

through 10A fuse (No. 72, located in IPDM E/R)

through IPDM E/R terminal 27

to front combination lamp RH terminal 2,

through 10A fuse (No. 74, located in IPDM E/R)

through IPDM E/R terminal 28

to front combination lamp LH terminal 2.

HEADLAMP - XENON TYPE -

Ground is supplied

to front combination lamp RH and LH terminals 5, and

to front combination lamp RH and LH terminals 4

through grounds E1 and E31.
With power and ground supplied, high beam headlamp illuminates.
The unified meter and A/C amp. receives high beam request signal (ON) through CAN communication, and
make high beam indicator lamp turn ON in combination meter.
FLASH-TO-PASS OPERATION
When the lighting switch is in PASSING position, BCM detects the PASSING (ON) by BCM combination switch
reading function. BCM sends low beam request signal (ON) and high beam request signal (ON) through CAN
communication.
When receiving low beam request signal (ON) and high beam request signal (ON), IPDM E/R turns ON head-
lamp low relay and headlamp high relay in IPDM E/R. And then, headlamp bulbs go ON. High beam solenoids
move the bulb shades in the front combination lamps to change beams from/to high and low. IPDM E/R sup-
plies power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 1,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 1,

through 10A fuse (No. 72, located in IPDM E/R)

through IPDM E/R terminal 27

to front combination lamp RH terminal 2,

through 10A fuse (No. 74, located in IPDM E/R)

through IPDM E/R terminal 28

to front combination lamp LH terminal 2.
Ground is supplied

to front combination lamp RH and LH terminals 5, and

to front combination lamp RH and LH terminals 4

through grounds E1 and E31.
With power and ground supplied, high beam headlamp illuminates.
The unified meter and A/C amp receives high beam request signal (ON) through CAN communication, and
make high beam indicator lamp turn ON in combination meter.
