7. CHECK TRUNK ROOM LAMP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check continuity between BCM harness connector and trunk
room lamp harness connector.
OK or NO
OK >> Replace BCM if trunk room lamp does not work after
setting the connector again. Refer to BCS-17, "
Removal
and Installation of BCM" .

1. Open driver and passenger window, and then disconnect battery
cable from the negative terminal.
CAUTION:
After battery cables are disconnected, never open/close
driver and/or passenger door with the window in the full up
position. Automatic window adjusting function will not
work and side roof panel may be damaged.
2. Remove lens using clip driver or suitable tool.

ILLUMINATION
Revision: 2006 November2007 350Z
ILLUMINATIONPFP:27545
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).

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
