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.

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.
