ILLUMINATION

ILLUMINATION
PFP:27545
Component Parts and Harness Connector Location
EKS009MX
System Description
EKS009MY
Control of the illumination lamps operation is dependent upon the position of the lighting switch (combination
switch). When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated)
the BCM (body control module) receives input signal requesting the illumination lamps to illuminate. This input
signal 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 tail lamp relay coil. This
relay, when energized, directs power to the illumination lamps, which then illuminate.
Power is supplied at all times
●
to ignition relay, located in the IPDM E/R, and
●
to tail lamp relay, located in the IPDM E/R, and
●
through 50A fusible link (letter g , located in the fuse and fusible link box)
●
to BCM terminal 70, and
●
through 20A fuse (No. 53, located in the IPDM E/R)
●
to CPU in the IPDM E/R, and
●
through 10A fuse [No.19, located in fuse block (J/B)]
