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 initialisation 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 initialisation is performed for RHD models for Europe,
security indicator will flash six times to demonstrate recogni-
tion of dongle ID.
