ILLUMINATIONPFP:27545
System DescriptionNKS003TH
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) located in the IPDM E/R controls the tail lamp relay
coil. This relay, when energized, directs power to the illumination lamps, which then illuminate.
OUTLINE
Power is supplied at all times
through 15A fuse (No. 71, located in IPDM E/R)
to tail lamp relay, located in IPDM E/R, and
to CPU located in IPDM E/R,
through 15A fuse (No. 78, located in IPDM E/R)
to CPU located in IPDM E/R,
through 50A fusible link (letter F, located in fuse, fusible link and relay block)
to BCM terminal 55,
through 10A fuse [No. 21, located in fuse block (J/B)]
to BCM terminal 42 and
to combination meter terminal 23,
through 10A fuse [No. 19, located in fuse block (J/B)]
to unified meter and A/C amp. terminal 54,
through 10A fuse [No. 22, located in fuse block (J/B)]
to intelligent key unit terminals 1, 41 and 57.
With the ignition switch in the ON or START position, power is supplied
through 15A fuse [No. 1, located in fuse block (J/B)]
to BCM terminal 38,
through 10A fuse [No. 14, located in fuse block (J/B)]
to combination meter terminal 12,
through 10A fuse [No. 12, located in fuse block (J/B)]
to unified meter and A/C amp. terminal 53 and
to rear sunshade cancel relay terminal 1.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM terminal 11
to unified meter and A/C amp. terminal 41 and
to combination meter terminal 2.
Ground is supplied
to BCM terminal 52
to unified meter and A/C amp. terminals 55 and 71
to combination meter terminals 9, 10, and 11
to Intelligent Key unit terminals 20, 40, 56 and 72, and
to illumination control switch terminal 3
through grounds M16 and M70,
