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.

lto BCM terminal 55 and
lto combination meter terminal 23
lthrough grounds M21, M80 and M83,
lto IPDM E/R terminals 38 and 59
lthrough grounds E21, E41 and E61.
DAYTIME LIGHT OPERATION
With the lighting switch in the OFF position and engine running, the BCM receives input signal requesting
headlamp low beam, clearance lamp, license plate lamp, and tail lamp to illuminate. This input signal is com-
municated to the IPDM E/R through the CAN communication. The CPU located in the IPDM E/R controls
headlamp low relay.

lto front combination lamp RH terminal 1,
lthrough 15A fuse (No. 40, located in IPDM E/R)
lthrough IPDM E/R terminal 52

Ground is supplied at all times
lto front combination lamp RH and LH terminals 3
lthrough grounds E21, E41 and E61.
With power and ground supplied, the headlamp low beam, clearance, license plate and tail lamps illuminate.
