DIAGNOSTIC PROCEDURE 9
Self-diagnostic results:
``LOCK MODE'' displayed on CONSULT screen
Con®rm SELF-DIAGNOSTIC RESULTS
``LOCK MODE'' is displayed on CONSULT
screen.
1. Turn the ignition switch to OFF position
and wait 1 minute.
(After 1 minute, security indicator will
blink.)
2. Turn the ignition key switch to ON posi-
tion with a registered key.
(Do not start engine.) Wait 5 seconds.
3. Return the key to the OFF position.
4. Repeat steps 2 and 3 twice (total of
three cycles).
5. Start the engine.
Does the engine start?
No
cYe s
System is OK.
(Now the system is
escaped from ``LOCK
MODE''.)
PERFORM INITIALISATION.
Perform initialisation with CONSULT.
For the initialisation procedure, refer to
``CONSULT operation manual NATS V2.0
(GASOLINE)''.
Can the system be initialised?
Note: If the initialisation is incompleted or
failed, CONSULT shows
mes-
sage on the screen.
No
cYe s
System is OK.
Go to DIAGNOSTIC PROCEDURE 5,
