CONSULT-II INSPECTION PROCEDURE
1. Turn ignition switch OFF.
2. Connect ªCONSULT-IIº to Data link connector.
3. Insert NATS program card into CONSULT-II.
: Program cardNATS (AEN02C-1)
4. Turn ignition switch ON.

CONSULT-II DIAGNOSTIC TEST MODE FUNCTION
CONSULT-II DIAGNOSTIC TEST
MODE Description
C/U INITIALIZATION When replacing any of the following components, C/U initialization is necessary. [NATS ignition key/IMMU/ECM/Dongle]
SELF-DIAGNOSTIC RESULTS Detected items (screen terms) are as shown in the chart below.
NOTE:
When any initialization is performed, all ID previously regis-
tered will be erased and all NATS ignition keys must be regis-
tered again.
The engine cannot be started with an unregistered key. In this
case, the system may show ªDIFFERENCE OF KEYº or ªLOCK
MODEº as a self-diagnostic result on the CONSULT-II screen.
When initialization is performed for RHD models for Europe,
security indicator will flash six times to demonstrate recogni-
tion of dongle ID.
