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.
●
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.
