Checks
Once in Diagnostic Mode (and after identifying the last three alarm triggers in case a theft warning system is
equipped on the vehicle), the following inputs can be tested.

Lighting switch turned 1st position or 2nd
position from offHazards flash once Tail lamp signal
Key put in ignition cylinder from out Hazards flash once Key in detect signal
Central unlock switch is pressed Hazards flash once Central unlock/Trunk release signal
*) Hazards may flash a second time because of Driver's door status signal change. The min. delay time between flash actions is
100 ms.
In case the system does not operate as described above, check the concerned circuit for open or short.
After completion, the Diagnostic Mode can be switched off by pressing the rear defogger switch or by turning
the ignition to ªONº. The hazard lamp will flash at 3 Hz for 3 seconds to confirm that Diagnostic Mode has
been switched off.

System Description
NATS has the following immobiliser functions:
IThis version of NATS has dongle control unit to improve its anti-theft performance (RHD models). Dongle
control unit has its own ID which is registered into NATS IMMU. So if dongle unit is replaced, initialization
must be carried out.
IWhen malfunction of dongle unit is detected:
The security indicator lamp illuminates for about 15 minutes after ignition switch is turned to ON.
Ð When dongle control unit has a malfunction, and the indicator lamp is illuminated, engine can not be
started. However engine can be started only one time when security indicator lamp turns off in about
15 minutes after ignition switch is turned to ON.
ISince only NATS ignition keys, whose ID nos. have been registered into the ECM and IMMU of NATS,
allow the engine to run, operation of a stolen vehicle without a NATS registered key is prevented by NATS.
That is to say, NATS will immobilize the engine if someone tries to start it without the registered key of
NATS.
IAll of the originally supplied ignition key IDs have been NATS registered.
If requested by the vehicle owner, a maximum of five key IDs can be registered into the NATS compo-
nents.
IThe NATS security indicator (NATS security ind.) 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.
IWhen NATS detects trouble, the security indicator lamp lights up as follows.

INATS trouble diagnoses, system initialisation and additional registration of other NATS ignition key IDs
must be carried out using CONSULT-II hardware and CONSULT-II NATS software.
Regarding the procedures of NATS initialisation and NATS ignition key ID registration, refer to CONSULT-II
operation manual, NATS.
IWhen servicing a malfunction of the NATS (indicated by lighting up of security Indicator Lamp) or
registering another NATS ignition key ID no., it may be necessary to re-register original key iden-
tification. Therefore, be sure to receive all keys and the PIN code from vehicle owner.

Installation
1. Install the front plate.
1) Install the O-ring and gasket to the cylinder block.
2) Install the front plate.
ILightly tap with a hammer if the dowel pin cannot be inserted
easily.
CAUTION:
Make sure that the O-ring does not pop out.
3) Apply Three Bond 1207C (KP510 00150) with a spreader
between the cylinder block plate under the cylinder block (oil
pan side) and the front plate (shown by the arrows in the fig-
ure).
2. Install the fuel injection pump.
IAfter installing the front plate, align the 6 mm (0.24 in) dia. hole
of the pump flange and the 6 mm (0.24 in) dia. hole position of
the pump body.
3. Install each timing gear.
IAlign the match marks of the timing gears by referring to the
figure below.
IWhen installing timing gear, follow the order (q
1,q2) shown in
the dotted box in the figure below to facilitate installation.

CONNECTING ROD BEARING OIL CLEARANCE
Method by measurement
IInstall connecting rod bearings to connecting rods and caps,
and tighten connecting nuts to the specified torque. Use inside
micrometer to measure connecting rod bearing inner diameter.
Bearing clearance = Connecting rod bearing inner diameter þ
Crankshaft pin outer diameter
Standard: 0.035 - 0.077 mm (0.0014 - 0.0030 in)
IIf out of specifications, check connecting rod big end inner
diameter and crankshaft pin outer diameter, and select appro-
priate connecting rod bearing to adjust clearance to specifica-
tions.
Refer to ªConnecting rod bearing undersize listº on the next
page.
Method using plastigage
IRemove contamination such as oil, dust completely from crank-
shaft pins and each bearing surface.
ICut plastigage slightly shorter than bearing width, place it in
crankshaft direction, avoiding oil holes.
IInstall connecting rod bearings to caps, and tighten connecting
rod nuts to the specified torque.
CAUTION:
Never rotate crankshaft.
IRemove connecting rod caps and bearings, and measure plas-
tigage width using scale on plastigage bag.
CAUTION:
If out of specification, take same action mentioned in ªMethod
by measurementº.
Undersize bearing usage
IIf bearing clearance is out of specifications for connecting rod
bearings in standard size, use undersize bearings.
IWhen using undersize bearings, measure bearing inner diam-
eter with bearing installed, and grind pins to adjust clearance
to specification.
