Removal and InstallationNJFE0002CAUTION:
+When removing accelerator wire, make a mark to indicate lock nut's initial position.
+Check that throttle valve opens fully when accelerator pedal is fully depressed. Also check that it
returns to idle position when pedal is released.
+Check accelerator control parts for improper contact with any adjacent parts.
+When connecting accelerator wire, be careful not to twist or scratch wire.

2. Connect suitable vacuum hose to vacuum pump as shown left.
3. Apply vacuum [more than þ40.0 kPa (þ400 mbar, þ300 mmHg,
þ11.81 inHg)] until the throttle drum becomes free from the rod
of the throttle opener.
Make sure that there is clearance between the throttle
drum and rod.
If NG, refer to EC-202, ªBasic Inspectionº.
If OK, go to following step.

combination meter. The indicator blinks when the ignition switch is
in ªOFFº or ªACCº 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 ªONº 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 ªONº position for approximately 5
seconds.
b) Turn ignition key to ªOFFº or ªLOCKº 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 PRECAUTIONSNJGI0001S03+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.
PRECAUTIONS
Precautions (Cont'd)

SEF289H
+Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
SGI233
+To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
SGI234
+Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
+Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
+Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
+Replace inner and outer races of tapered roller bearings and
needle bearings as a set.
+Arrange the disassembled parts in accordance with their
assembled locations and sequence.
+Do not touch the terminals of electrical components which use
microcomputers (such as ECMs).
Static electricity may damage internal electronic components.
+After disconnecting vacuum or air hoses, attach a tag to indi-
cate the proper connection.
+Use only the fluids and lubricants specified in this manual.
+Use approved bonding agent, sealants or their equivalents
when required.
+Use tools and recommended special tools where specified for
safe and efficient service repairs.
+When repairing the fuel, oil, water, vacuum or exhaust
systems, check all affected lines for leaks.
+Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
