tor.
CHECK FUEL LEVEL SENSOR UNIT.
Refer to ªFUEL LEVEL SENSOR UNIT
CHECKº (EL-98).
OK
ENGReplace fuel level sensor
unit.

Electrical Components Inspection
DIODE CHECK
ICheck continuity using an ohmmeter.
I Diode is functioning properly if test results are as shown in the
figure at left.
I Check diodes at the combination meter harness connector
instead of on the combination meter assembly. Refer to ªWarn-
ing Lamp/Wiring Diagramº, EL-100.
NOTE:
Specification may vary depending on the type of tester. Before
performing this inspection, be sure to refer to the instruction
manual for the tester to be used.
Oil Pressure Switch Check
Check the continuity between the terminals of oil pressure switch
and body ground.

System Description
NATS has the following immobilizer 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.
I When 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.
I Since 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.
I All 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.
I The 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.
I When NATS detects trouble, the security indicator lamp lights up as follows.

I
NATS trouble diagnoses, system initialization 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 initialization and NATS ignition key ID registration, refer to CONSULT-II
operation manual, NATS.
I When 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.
