Diagnostic Procedure
AT-65
Regarding the procedures of NATS initialisation and NATS igni-
tion key ID registration, refer to CONSULT-II operation manual
for 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.
lWhen servicing NATS (trouble diagnoses, system initialisa-
tion and additional registration of other NATS ignition key
IDs), it may be necessary to re-register original key identifi-
cation. Therefore, be sure to obtain all keys from vehicle
owner.
A maximum of four key IDs can be registered into NATS.
Precautions for Super Lock System
Locking the driver's door or front passenger's door with the key
or remote control will lock all doors and activate the Super Lock
System.
The Super Lock System is designed to prevent theft as it can
only be released when a front door is unlocked using a key or
remote control.
This means, none of the door locks can be operated from the
inside using the door lock knob when the Super Lock System is
activated.
General Precautions
lDo not operate the engine for an extended period of time
without proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any
flammable 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
hazardous materials.
Do not smoke while working on the vehicle.
lBefore 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
working on the vehicle.
These operations should be done on a level surface.
lWhen removing a heavy component such as the engine or
transaxle/transmission, 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.
