The security indicator is located on the instrument panel. The indi-
cator blinks when the ignition switch is in“OFF”or“ACC”position.
Therefore, NATS warns outsiders that the vehicle is equipped with
the anti-theft system.
+When NATS detects trouble, the security indicator lamp lights
up while ignition switch is in“ON”position.
This lighting up indicates that the anti-theft is not functioning,
so prompt service is required.
+When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs),
CONSULT-II hardware and CONSULT-II NATS software is
necessary.
Regarding the procedures of NATS initialization and NATS
ignition key ID registration, refer to CONSULT-II operation
manual, NATS.
Therefore, CONSULT-II NATS software (program card and
operation manual) must be kept strictly confidential to main-
tain the integrity of the anti-theft function.
+When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs), it
may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A
maximum of five key IDs can be registered into NATS.
+When failing to start the engine first time using the key of
NATS, start as follows.
a) Leave the ignition key in“ON”position for approximately 5
seconds.
b) Turn ignition key to“OFF”or“LOCK”position and wait approxi-
mately 5 seconds.
c) Repeat step 1 and 2 again.
d) Restart the engine while keeping the key separate from any
others on key-chain.

GENERAL PRECAUTIONSNLGI0001S03+Do not operate the engine for an extended period of time
without proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refrig-
erant gas, etc. When working in a pit or other enclosed area,
be sure to properly ventilate the area before working with haz-
ardous materials.
Do not smoke while working on the vehicle.
SGI231
+Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before work-
ing on the vehicle.
These operations should be done on a level surface.
+When removing a heavy component such as the engine or
transaxle, be careful not to lose your balance and drop them.
Also, do not allow them to strike adjacent parts, especially the
brake tubes and master cylinder.

+To reinstall the rubber hose securely, make sure of hose inser-
tion length and clamp orientation. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)
SMA021D
Hose ClampingNLGI0001S0602+If old rubber hose is re-used, install hose clamp in its original
position (at the indentation where the old clamp was). If there
is a trace of tube bulging left on the old rubber hose, align
rubber hose at that position.
+Discard old clamps; replace with new ones.
SMA022D
+After installing leaf spring clamps, apply force to them in the
direction of the arrow, tightening rubber hose equally all
around.
PRECAUTIONS FOR ENGINE OILSNLGI0001S07Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner
as soon as possible.
Health Protection PrecautionsNLGI0001S0701+Avoid prolonged and repeated contact with oils, particularly
used engine oils.
+Wear protective clothing, including impervious gloves where
practicable.
+Do not put oily rags in pockets.
+Avoid contaminating clothes, particularly underclothing, with
oil.
+Heavily soiled clothing and oil-impregnated footwear should
not be worn. Overalls must be cleaned regularly.
+First Aid treatment should be obtained immediately for open
cuts and wounds.
+Use barrier creams, applying them before each work period, to
help the removal of oil from the skin.
+Wash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations containing
lanolin replace the natural skin oils which have been removed.

GROUND INSPECTIONNLGI0005S0304Ground 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 corro-
sion (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 drastically affect an
electronically controlled circuit. A poor or corroded ground can eas-
ily affect the circuit. Even when the ground connection looks clean,
there can be a thin film of rust on the surface.
When inspecting a ground connection follow these rules:
1) Remove the ground bolt or screw.
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.
SGI853
VOLTAGE DROP TESTSNLGI0005S0305Voltage drop tests are often used to find components or circuits
which have excessive resistance. A voltage drop in a circuit is
caused by a resistancewhen the circuit is in operation.
Check the wire in the illustration. When measuring resistance with
ohmmeter, contact by a single strand of wire will give reading of 0
ohms. This would indicate a good circuit. When the circuit operates,
this single strand of wire is not able to carry the current. The single

Nickel Metal Hydride Battery ReplacementNLGI0007S06CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with Genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if
mistreated. Do not recharge, disassemble or dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.

3. Move probe along component approximately 25 to 50 mm (1
to 2 in)/sec.
Checking ProcedureNLHA0168S03To prevent inaccurate or false readings, make sure there is no
refrigerant vapor, shop chemicals, or cigarette smoke in the
vicinity of the vehicle. Perform the leak test in calm area (low
air/wind movement) so that the leaking refrigerant is not dis-
persed.
1. Turn engine off.
2. Connect a suitable A/C manifold gauge set to the A/C service
ports.
3. Check if the A/C refrigerant pressure is at least 345.2 kPa (3.45
bar, 3.52 kg/cm
2, 50.1 psi) above 16°C (61°F). If less than
specification, recover/evacuate and recharge the system with
the specified amount of refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected
since the system may not reach 345.2 kPa (3.45 bar, 3.52 kg/cm
2,
50.1 psi).
4. Conduct the leak test from the high side (compressor dis-
chargeato evaporator inletg) to the low side (evaporator drain
hosehto shaft sealk). Refer to HA-98. Perform a leak check
for the following areas carefully. Clean the component to be
checked and move the leak detector probe completely around
the connection/component.
+Compressor
Check the fitting of high and low pressure hoses, relief valve
and shaft seal.
+Liquid tank
Check the pressure switch, refrigerant pressure sensor, tube
fitting, weld seams and the fusible plug mount.
+Service valves
Check all around the service valves. Ensure service valve caps
are secured on the service valves (to prevent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe
any residue from valves to prevent any false readings by leak
detector.
+Cooling unit (Evaporator)
With engine OFF, turn blower fan on“High”for at least 15
seconds to dissipate any refrigerant trace in the cooling unit.
Wait a minimum of 10 minutes accumulation time (refer to the
manufacturer’s recommended procedure for actual wait time)
before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least ten seconds. Use caution
not to contaminate the ptobe tip with water or dirt that may be
in the drain hose.

CAUTION:
+When removing water pump assembly, be careful not to
get coolant on drive belt.
+Water pump cannot be disassembled and should be
replaced as a unit.
+After installing water pump, connect hose and clamp
securely, then check for leaks using radiator cap tester.
