System DescriptionNKS004WN
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
signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/
R (intelligent power distribution module engine room) through the CAN communication lines. The CPU (central
processing unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. These relays,
when energized, direct power to the respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times

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

to headlamp low relay, located in IPDM E/R, from battery directly,

through 40A fusible link [letter F, located in fuse, fusible link and relay box]

to BCM terminal 55,

through 10A fuse [No.18, located in fuse block (J/B)]

to BCM terminal 42,

through 15A fuse [No.78 located in IPDM E/R]

to CPU located in IPDM E/R,

through 10A fuse [No.71,located in IPDM E/R]

to CPU located in IPDM E/R,

through 10A fuse [No.19, located in fuse block (J/B)]
