HEADLAMP (FOR USA)PFP:26010
Component Parts and Harness Connector LocationEKS00B7S
System DescriptionEKS00B7T
Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
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 (intelligent
power distribution module engine room) across the CAN communication lines. 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.
OUTLINE
Power is supplied at all times

to ignition relay, located in the IPDM E/R, and

to headlamp high relay, located in the IPDM E/R, and

to headlamp low relay, located in the IPDM E/R, and

through 20A fuse (No. 53, located in the IPDM E/R)

to CPU of the IPDM E/R, and

through 50A fusible link (letter f , located in the fuse and fusible link box)
