ILLUMINATION
Revision: June 20062007 Versa
ILLUMINATIONPFP:27545
System DescriptionEKS00HZU
The control of the illumination lamps operation is dependent upon the position of the lighting switch. When the
lighting switch is placed in the 1ST or 2ND position, the BCM (body control module) receives input signal
requesting the illumination lamps to illuminate. This input signal is communicated to IPDM E/R (intelligent
power distribution module engine room) across CAN communication lines. CPU (central processing unit)
located in the IPDM E/R controls the tail lamp relay coil. This relay, when energized, directs power to the illu-
mination lamps, which then illuminate.
Power is supplied at all times
to ignition relay, located in IPDM E/R,
to tail lamp relay, located in IPDM E/R,
through 15A fuse (No. 52, located in IPDM E/R) and
through 20A fuse (No. 53, located in IPDM E/R)
to CPU located in IPDM E/R,
through 40A fusible link (letter g , located in fuse and fusible link box)
to BCM terminal 70, and
through 10A fuse [No. 8, located in fuse block (J/B)]
to BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied
to ignition relay, located in IPDM E/R, and
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 20, located in fuse block (J/B)]
to BCM terminal 11.
Ground is supplied
to BCM terminal 67
through grounds M57 and M61, and
to IPDM E/R terminals 39 and 59
through grounds E15 and E24.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, BCM receives input signal requesting the illumination
lamps to illuminate. This input signal is communicated to IPDM E/R across CAN communication lines. CPU
located in the IPDM E/R controls the tail lamp relay coil, which, when energized, directs power
through 10A fuse (No. 37, located in IPDM E/R)
through IPDM E/R terminal 29
to microphone terminal 3 (with Bluetooth)
to illumination control switch terminal 1
to glove box lamp terminal 1 (with glovebox lamp)
to audio unit terminal 9
to front air control terminal 5
to A/T device terminal 3 (without M/T)
to hazard switch terminal 3
to combination meter terminal 12

exhaust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it.MA-20
UnderbodyThe underbody is frequently exposed to corrosive substances such as those used
on icy roads or to control dust. It is very important to remove these substances,
otherwise rust will form on the floor pan, frame, fuel lines and around the exhaust
system. At the end of winter, the underbody should be thoroughly flushed with
plain water, being careful to clean those areas where mud and dirt can easily
accumulate.—
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the air conditioner after use is nor-
mal. If you should notice any leaks or gasoline fumes are evident, check for the
cause and correct it immediately.—

PRECAUTIONS
Revision: June 20062007 Versa
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied oils have been used with the scale. If the scale controls refriger-
ant flow electronically, the hose fitting must be 1/2″-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Precautions for Leak Detection DyeEJS00572
The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to pin-
point refrigerant leaks.
For your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.
A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal
should only be repaired after confirming the leak with an electronic refrigerant leak detector.
Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis
during a future service.
Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period
of time cannot be removed.
Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
Do not use more than one refrigerant dye bottle (1/4 ounce /7.4 cc) per A/C system.
