PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
Component Parts and Harness Connector LocationNKS003SH
System DescriptionNKS003SI
The control of the parking, license plate and tail lamp 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 parking, license plate and tail lamps to illuminate. This input sig-
nal 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 parking, license plate and tail lamps, which then illuminate.
OUTLINE
Power is supplied at all times
through 15A fuse (No. 71, located in IPDM E/R)
to CPU located in IPDM E/R, and
to tail lamp relay 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)]

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.

(position “1”)
–Tip clearance between oil pump inner rotor and oil pump outer
rotor (position “2”)
–If out of the standard, replace inner rotor and outor rotor.
Measure the clearance with feeler gauge and straightedge.
–Side clearance between oil pump inner rotor and oil pump body
(position “3”)
–Side clearance between oil pump outer rotor and oil pump body
(position “4”)
Calculate the clearance between oil pump inner rotor and oil pump body as follows:
