ignition NISSAN TERRANO 2004 Service Repair Manual

Observe the following precautions to ensure safe and proper
servicing. These precautions are not described in each indi-
vidual section.
1. Do not operate the engine for an extended period of time with-out 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, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.
2. 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 and towing
before working on the vehicle.
These operations should be done on a level surface.
3. When removing a heavy component such as the engine or transaxle/transmission, take care not to lose your balance and
drop it. Also, do not allow it to strike adjacent parts, especially
the brake tubes and master cylinder.
4. Before starting repairs which do not require battery power, always turn off the ignition switch, then disconnect the ground
cable from the battery to prevent accidental short circuit.
5. To prevent serious burns, avoid contact with hot metal parts such as the radiator, exhaust manifold, tail pipe and muffler. Do
not remove the radiator cap when the engine is hot.

insulation (either just before the harness connectors or for

Precautions for NATS
NATS (Nissan Anti-Theft System)
NATS will immobilize the engine if someone tries to start it without
the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS
registered.
The NATS security indicator is located on the instrument panel. The
indicator blinks when the ignition switch is in ªOFFº or ªACCº posi-
tion. Therefore, NATS warns outsiders that the vehicle is equipped
with the anti-theft system.
IWhen NATS detects trouble, the malfunction indicator lamp
(MIL) blinks.
This blinking indicates that the anti-theft is not functioning, so
prompt service is required.
I If the malfunction indicator lamp comes on while the engine is
running, return the vehicle to the workshop before turning the
ignition switch ªOFFº.
Once the ignition switch is turned ªOFFº, the engine can not be
started.
I When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs) CON-
SULT-II hardware and CONSULT-II NATS software is neces-
sary.
Regarding the procedures of NATS initialization and NATS igni-
tion 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.
I 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.
I When failing to start the engine first-time using the key of
NATS, starts as follows:
(1) Turn ignition key to ªOFFº.
(2) Wait approx. 5 seconds.
(3) Turn ignition key to ªSTARTº again while keeping the key
apart from any others on key-chain.

Precautions for Multiport Fuel Injection System
or Engine Control System
1. Before connecting or disconnecting any harness connector forthe multiport fuel injection system or ECM (Engine Control
Module):
Turn ignition switch to ªOFFº position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
2. Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure to eliminate danger.
3. Be careful not to jar components such as control unit and air flow meter.
Precautions for Catalyst
If a large amount of unburned fuel enters the converter, the con-
verter temperature will rise to excessively high values. To prevent
this, follow the procedure below:
1. Use unleaded gasoline only. Leaded gasoline will seriouslydamage the catalytic converter.
2. When checking for ignition spark or measuring engine compression, perform tests quickly and only when necessary.
3. Do not run engine when the fuel tank level is low, as a result the engine may misfire causing damage to the converter.
4. Do not place the vehicle on inflammable material. Keep inflam- mable material off the exhaust pipe.
Precautions for Turbocharger
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean
supply of oil flowing through the turbocharger and to follow all
required maintenance instructions and operating procedures.
For proper operation of the system, follow the procedure below:
1. Always use the recommended oil. Follow the instructions forproper time to change the oil and proper oil level.
2. Avoid accelerating engine to a high rpm immediately after start- ing.
3. If engine had been operating at high rpm for an extended period of time, let it idle for a few minutes prior to shutting it off.

Nickel Metal Hydride Battery Replacement
CONSULT-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 battery
may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if mis-
treated. Do not recharge, disassemble of dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.

4-pole Lift
WARNING:
Do not use a 2-pole lift.
Due to weight balance of the vehicle and shape of underbody,
lift arms can not be attached in a safe way. Therefore it is rec-
ommended to use a 4-pole lift only.
Tow Truck Towing
CAUTION:
IAll applicable local laws regarding the towing operation
must be obeyed.
I It is necessary to use proper towing equipment to avoid
possible damage to the vehicle during a towing operation.
I Attach safety chains for all towing.
I 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.
I When towing with the front wheels on the ground:
Move both the gearshift and transfer levers to neutral (ªNº
position).
Turn the ignition key to the ªOFFº position and secure the
steering wheel in a straightahead position with a rope or
similar device. Never place the ignition key in the ªLOCKº
position. This will result in damage to the steering lock
mechanism.
I When towing with the rear wheels on the ground, release
the parking brake and move both the gearshift and trans-
fer levers to neutral (ªNº position).
I Never tow vehicle from the rear (i.e., backward) with four
wheels on the ground as this may cause serious and
expensive damage to the transmission.
