4.CHECK INTERIOR ROOM LAMP CIRCUIT
1. Disconnect BCM connector and front map lamp connector.
2. Check continuity between BCM harness connector (A) and front
map lamp harness connector (B).
OK or NG
OK >> Replace BCM if interior lamp does not work after setting
the connector again. Refer toBCS-17, "
Removal and
Installation of BCM".
NG >> Repair harness or connector.
5.CHECK INTERIOR ROOM LAMP CIRCUIT
1. Disconnect BCM connector and front map lamp connector.
2. Check continuity between BCM harness connector (A) and front
map lamp harness connector (B).
OK or NG
OK >> Replace BCM if interior lamp does not work after setting
the connector again. Refer toBCS-17, "
Removal and
Installation of BCM".

All Interior Room Lamps Do Not OperateEKS00P9B
1.CHECK POWER SUPPLY CIRCUIT
1. All interior room lamp switches are OFF.
2. Turn ignition switch ON.
3. Check voltage between BCM harness connector and ground.
OK or NG
OK >> Repair harness or connector. In a case of making a
short circuit, be sure to disconnect battery negative cable after repairing harness, and then recon-
nect.
NG >> Replace BCM. Refer toBCS-17, "

ILLUMINATION
ILLUMINATION
PFP:27545
System DescriptionEKS00P8V
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 position, 2ND position or AUTO position (headlamp is
ON) 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) through the
CAN communication. 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
lto ignition relay (located in IPDM E/R) and
lto tail lamp relay (located in IPDM E/R), from battery directly,
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 20A fuse (No. 52, located in IPDM E/R) and
lthrough 20A fuse (No. 53, located in IPDM E/R)
lto CPU (located in IPDM E/R),
lthrough 10A fuse [No.19, located in fuse block (J/B)]
lto combination meter terminal 3.
With the ignition switch in the ON or START position, power is supplied
lto ignition relay (located in IPDM E/R),
lthrough 10A fuse [No. 1, located in fuse block (J/B)]
lto BCM terminal 3,
lthrough 10A fuse [No. 14, located in fuse block (J/B)]
lto combination meter 16.
Ground is supplied
lto BCM terminal 55 and
lto combination meter terminal 23
lthrough grounds M21, M80 and M83,
lto IPDM E/R terminals 38 and 59
lthrough grounds E21, E41 and E61.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST position, 2ND position or AUTO position (headlamp is ON), the BCM
receives input signal requesting the illumination lamps to illuminate. This input signal is communicated to the
IPDM E/R through the CAN communication. The CPU of the IPDM E/R controls the tail lamp relay coil, which,
when energized, directs power
lthrough 10A fuse (No. 37, located in IPDM E/R)
lthrough IPDM E/R terminal 57
lto hazard switch (illumination) terminal 3
lto 4WD shift switch (illumination) terminal 7 (with 4-wheel drive)
lto front air control (illumination) terminal 8

CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and “CON-
SULT-II converter” to the data link connector, and turn the igni-
tion switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “BCM” on “SELECT SYSTEM” screen. If “BCM” is not
indicated, go toGI-50, "
CONSULT-II Data Link Connector (DLC)
Circuit".
