CONSULT-II 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 carries out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, refer toGI-50, "

PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
Component Parts and Harness Connector LocationEKS00P9C
System DescriptionEKS00P9D
Control of the clarence, license plate, and tail lamps operation is dependent upon the position of the lighting
switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body control
module) receives input signal requesting the clarence, license plate and tail lamps to illuminate. This input sig-
nal 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 clarence, license plate and tail lamps, which then illuminate.
OUTLINE
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 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 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57.
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.
Ground is supplied
lto BCM terminal 55
lthrough grounds M21, M80 and M83,
lto IPDM E/R terminals 38 and 59
