7. Select “NATS V.5.0”.
If “NATS V5.0” is not indicated, go to GI-39, "
CONSULT-II Data
Link Connector (DLC) Circuit" .
8. Perform each diagnostic test mode according to each service
procedure.
For further information, see the CONSULT-II Operation Manual
NATS-IVIS/NVIS.
CONSULT-II DIAGNOSTIC TEST MODE FUNCTION
NOTE:

When any initialization is performed, all ID previously registered will be erased and all NATS ignition keys
must be registered again.

The engine cannot be started with an unregistered key. In this case, the system will show “DIFFERENCE
OF KEY” or “LOCK MODE” as a self-diagnostic result on the CONSULT-II screen.

NATS V5.0C/U INTIALIZATIONPerform registration again after repair, part replacement, and
additional key ID registration.
CAUTION:
“Control Unit Initialization” is activated only after per-
forming “Release steering lock”.Refer to the
Technical Bul-
letin.
