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.

3. Remove injection tube and injection nozzle assembly. Refer toEC section, ªInjection Tube and Injection Nozzleº in ªBASIC
SERVICE PROCEDUREº.
4. Remove the camshaft.
I Place distinguishing marks on the right and left sides with paint.
I Loosen and remove the installation bolt in reverse order shown
in the figure.
5. Remove the adjusting shim and valve lifter.
I Remove by taking notice of the installation position, and place
outside engine in order to prevent confusion.
Inspection
VISUAL CHECK OF CAMSHAFT
ICheck the camshaft for one sided wear or scratches.
I Replace the camshaft if there are abnormalities.
CAMSHAFT RUNOUT
IPrepare V-block on a flat surface and secure camshaft journals
No. 1 and No. 5.
I Set the dial gauge vertically on journal No. 3.
I Rotate camshaft in one direction by hand, then read needle
movement on dial indicator.
Camshaft bend value is 1/2 of needle movement.
