Voltage check method
1. Remove the blown fuse and disconnect all loads (i.e. SW1 open, relay disconnected and solenoid discon-
nected) powered through the fuse.
2. Turn the ignition key to the ON or START position. Verify battery voltage at the B
+side of the fuse ter-
minal (one lead on the B
+terminal side of the fuse block and one lead on a known good ground).
3. With SW1 open and the DMM leads across both fuse terminals, check for voltage.
voltage; short is between fuse block and SW1 (point A).
no voltage; short is further down the circuit than SW1.
4. With SW1 closed, relay and solenoid disconnected and the DMM leads across both fuse terminals, check
for voltage.
voltage; short is between SW1 and the relay (point B).
no voltage; short is further down the circuit than the relay.
5. With SW1 closed, relay contacts jumped with fused jumper wire check for voltage.
voltage; short is down the circuit of the relay or between the relay and the disconnected solenoid
(point C).
no voltage; retrace steps and check power to fuse block.
GROUND INSPECTION
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground
connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become
an unwanted resistance. This unwanted resistance can change the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can dras-
tically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even
when the ground connection looks clean, there can be a thin ®lm of rust on the surface.
When inspecting a ground connection follow these rules:
1. Remove the ground bolt screw or clip.
2. Inspect all mating surfaces for tarnish, dirt, rust, etc.
3. Clean as required to assure good contact.
4. Reinstall bolt or screw securely.
5. Inspect for ``add-on'' accessories which may be interfering with the ground circuit.
6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the
wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one
eyelet make sure no ground wires have excess wire insulation.

Lithium Battery Replacement
CONSULT contains a lithium battery. When replacing the battery obey the following:
WARNING:
Replace the lithium battery with SANYO Electric Co., Ltd., CR2032 only. Use of another battery may
present a risk of ®re or explosion. The battery may present a ®re or chemical burn hazard if mistreated.
Do not recharge, disassemble of dispose of in ®re.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.

Tow Truck Towing
CAUTION:
+All applicable local laws regarding the towing operation
must be obeyed.
+It is necessary to use proper towing equipment to avoid
possible damage to the vehicle during a towing operation.
+Attach safety chains for all towing.
+When towing, make sure that the transmission, steering
system and power train are in good order. If any unit is
damaged, a dolly must be used.
+When towing with the front wheels on the ground:
Turn the ignition key to the ``OFF'' position and secure the
steering wheel in a straight-ahead position with a rope or
similar device. Never place the ignition key in the ``LOCK''
position. This will result in damage to the steering lock
mechanism.
+When towing manual transmission models with the rear
wheels on the ground:
Release the parking brake and move the gearshift lever to
neutral (``N'' position).
+For 4-wheel drive models:
Set the manual-lock free-running hubs to the free position and
2-way lock free-running hubs to the auto position. (See
``
Transfer case shifting procedures for 4-wheel drive
vehicles'' in ``Starting and driving'' section.) Move the transfer
case shift lever into the ``2H'' position and the transmission shift
lever into the neutral (``N'') position.
Do not shift the transfer lever to the ``4L'' position. This will
cause damage to the transmission.
NISSAN recommends that a dolly be used as illustrated.
If you have to tow a manual transmission model with front
wheels raised (with rear wheels on ground)
Observe the following restricted raising heights.
+Do not raise the front end over!.
Wagon
!= 600 mm (23.62 in)
Hardtop
!= 500 mm (19.69 in)
