HEADLAMP -CONVENTIONAL TYPE-PFP:26010
Component Parts and Harness Connector LocationEKS00P7H
System DescriptionEKS00P7I
The control of the headlamp system operation is dependent upon the position of the combination switch (light-
ing switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives
input requesting the headlamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intel-
ligent power distribution module engine room) through the CAN communication. The CPU (central processing
unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized, these relays
direct power to the respective headlamps, which then illuminate.

Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This
input is communicated to the IPDM E/R through the CAN communication. The CPU of the IPDM E/R controls
the headlamp low relay coil. When energized, this relay directs power

Ground is supplied
lto front combination lamp RH and LH terminals 3
lthrough grounds E21, E41 and E61.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input request-
ing the headlamp high beams to illuminate. This input is communicated to the IPDM E/R through the CAN
communication. The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay
directs power
lthrough 10A fuse (No. 34, located in IPDM E/R)
lthrough IPDM E/R terminal 56
lto front combination lamp RH terminal 2,
lthrough 10A fuse (No. 35, located in IPDM E/R)
lthrough IPDM E/R terminal 55
lto front combination lamp LH terminal 2.
Ground is supplied
lto front combination lamp RH and LH terminals 3
lthrough grounds E21, E41 and E61.
With power and ground supplied, the high beam headlamps illuminate.
Combination meter that received high beam request signal by BCM through the CAN communication makes a
high beam indicator lamp turn on in combination meter.
FRIENDLY LIGHTING FUNCTION
This function starts timer function of BCM by operating passing switch, and illuminates headlamps (LOW
beam) for a given length of time.
Headlamps (LOW beam) stay ON for a given length of time by operating passing switch when ignition switch is
OFF and lighting switch is OFF.
Headlamps (LOW beam) stays ON for two minutes at a maximum by operating passing switch repeatedly.
CONSULT-II is capable of setting a lighting time. Refer toLT- 1 6 , "
WORK SUPPORT".

HEADLAMP - DAYTIME LIGHT SYSTEM -PFP:26010
Component Parts and Harness Connector LocationEKS00Q7E
System DescriptionEKS00Q7F
The daytime light system is to illuminate headlamp low beam, clearance lamps, tail lamps and license plate
lamps while the engine is running.
When the engine is running, the BCM (body control module) receives the engine status signal. Then the BCM
sends the headlamp low beam request signal and the daytime light request signal to the IPDM E/R (intelligent
power distribution module engine room) through the CAN communication. As the IPDM E/R receives the
above request signals, its CPU (central processing unit) controls headlamp low relay to illuminate headlamp
low beam, clearance lamps, tail lamps and license plate lamps.

municated to the IPDM E/R through the CAN communication. The CPU located in the IPDM E/R controls
headlamp low relay.
