Description
C/U INITIALIZATION
When replacing any of the following components, C/U initialization and re-registration of all
NATS ignition keys are necessary.
[NATS ignition key/IMMU/ECM/Dongle unit]
SELF-DIAG RESULTS
Detected items (screen terms) are as shown in the chart EL-356.
NOTE:
I
When any initialization is performed, all ID previously reg-
istered will be erased and all NATS ignition keys must be
registered again.
I
The engine cannot be started with an unregistered key. In this
case, the system may show “DIFFERENCE OF KEY” or
“LOCK MODE” as a self-diagnostic result on the CONSULT-II
screen.
I
When initialization is performed for RHD models for Europe,
security indicator will flash six times to demonstrate recognition
of the dongle unit ID.
I
In rare case, “CHAIN OF ECM-IMMU” might be stored as a
self-diagnostic result during key registration procedure, even if
the system is not malfunctioning.
