The security indicator is located on the combi 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.

SWITCH POSITIONSNJGI0003S0204Switches are shown in wiring diagrams as if the vehicle is in the
ªnormalº condition.
A vehicle is in the ªnormalº condition when:
+ignition switch is ªOFFº,
+doors, hood and trunk lid/back door are closed,
+pedals are not depressed, and
+parking brake is released.
DETECTABLE LINES AND NON-DETECTABLE LINESNJGI0003S0205In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
+A line with regular weight (wider line) represents a ªdetectable
line for DTC (Diagnostic Trouble Code)º. A ªdetectable line for
DTCº is a circuit in which ECM can detect its malfunctions with
the on board diagnostic system.
+A line with less weight (thinner line) represents a ªnon-detect-
able line for DTCº. A ªnon-detectable line for DTCº is a circuit
in which ECM cannot detect its malfunctions with the on board
diagnostic system.

+When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
MEF040DA
+Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions prop-
erly or not. (See page AT-116.)
SAT964I
+After performing each TROUBLE DIAGNOSIS, perform
ªDTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DUREº.
The DTC should not be displayed in the ªDTC CONFIRMA-
TION PROCEDUREº if the repair is completed.
+Before proceeding with disassembly, thoroughly clean the out-
side of the transaxle. It is important to prevent the internal parts
from becoming contaminated by dirt or other foreign matter.
+Disassembly should be done in a clean work area.
+Use lint-free cloth or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the opera-
tion of the transaxle.
+Place disassembled parts in order for easier and proper
assembly.
+All parts should be carefully cleaned with a general purpose,
non-flammable solvent before inspection or reassembly.
+Gaskets, seals and O-rings should be replaced any time the
transaxle is disassembled.
+It is very important to perform functional tests whenever they
are indicated.
+The valve body contains precision parts and requires extreme
care when parts are removed and serviced. Place disas-
sembled valve body parts in order for easier and proper
assembly. Care will also prevent springs and small parts from
becoming scattered or lost.
+Properly installed valves, sleeves, plugs, etc. will slide along
bores in valve body under their own weight.
+Before assembly, apply a coat of recommended ATF to all
