System DescriptionNKS004ZY
Control of the illumination lamp operation is dependent upon the position of the lighting switch (combination
switch). When the lighting switch is placed in the 1ST or 2ND position, the BCM (body control module)
receives input signal requesting illumination lamps to 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) located in the IPDM E/R controls tail lamp relay coil. This relay, when energized,
directs power to illumination lamps, which then illuminate.
OUT LINE
Power is supplied at all times
through 10A 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.
Power is also supplied at all times
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 10A fuse [No.19, located in fuse block (J/B)]
to unified meter and A/C amp. terminal 21,
through 10A fuse [No.19, located in fuse block (J/B)]
to combination meter terminal 24.
With ignition switch in the ON or START position, power is supplied
to CPU located in IPDM E/R,
through 10A fuse [No.1, located in fuse block (J/B)]
to BCM terminal 38,
through 10A fuse [No.12, located in fuse block (J/B)]
to unified meter and A/C amp. terminal 22, and
to NAVI control unit terminal 63 (With navigation system),
through 10A fuse [No.14, located in fuse block (J/B)]
to combination meter terminal 23.
With 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.
Ground is supplied
to BCM terminal 52
through grounds M30 and M66,
to IPDM E/R terminals 38 and 60
through grounds E17, E43 and B102 (with VDC system, navigation system or telephone)
through grounds E17, E43 and F152 (without VDC system, navigation system and telephone),
to unified meter and A/C amp. terminals 29 and 30
through grounds M30 and M66,
to combination meter terminals 10, 11 and 12
through grounds M30 and M66,
to NAVI control unit terminal 1 (With navigation system)
through ground B115 (With navigation system).

ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, the BCM receives input signal requesting illumination
lamps to illuminate. This input signal is communicated to the IPDM E/R through the CAN communication lines.
CPU located in the IPDM E/R controls tail lamp relay coil, which, when energized, directs power
through terminal 22 of IPDM E/R
to NAVI control unit terminal 61 (With navigation system)
to NAVI switch terminal 2 (With navigation system)
to audio unit terminal 8.
to combination switch (spiral cable) terminal 26 (with steering switch)
to soft top switch (illumination) terminal 5 (Roadster model)
to A/T device (A/T illumination) terminal 3 (With A/T)
to VDC off switch (illumination) terminal 3 (With VDC)
to TCS off switch (illumination) terminal 3 (With TCS)
to map lamp (illumination) terminal 4 (Roadster models)
to hazard switch (illumination) terminal 3
to heated seat switch (driver side) (illumination) terminal 5 (With hated seat)
to heated seat switch (passenger side) (illumination) terminal 5 (With heated seat)
to bottle holder illumination (driver side) terminal 1
to bottle holder illumination (passenger side) terminal 1
to cup holder illumination terminal 1
to luggage floor box lamp terminal 1.
Ground is supplied at all times
to NAVI control unit terminal 1 (with navigation system)
through ground B115,
to NAVI switch terminal 3 (With navigation system)
to audio unit terminal 7
to combination switch (spiral cable) terminal 27 (with steering switch)
to soft top switch (illumination) terminal 6 (Roadster models)
to A/T device (A/T illumination) terminal 5 (With A/T)
to VDC off switch (illumination) terminal 4 (With VDC)
to TCS off switch (illumination) terminal 4 (With TCS)
to hazard switch (illumination) terminal 4
to heated seat switch (driver side) (illumination) terminal 6 (With heated seat)
to heated seat switch (passenger side) (illumination) terminal 6 (With heated seat)
to bottle holder illumination (driver side) terminal 2, and
to bottle holder illumination (passenger side) terminal 2
through combination meter terminal 18,
to map lamp (illumination) terminal 1 (Roadster models)
to cup holder illumination terminal 2
through grounds M30 and M66,
to luggage floor box lamp terminal 2
through grounds B5, B6, D105 and T14 (Coupe model)
through grounds B5, B6 and T14 (Roadster model).
With power and ground supplied, illumination lamps illuminate.
