*: When replace ECM, refer to BL-249, "ECM Re-communicating Function" .
NOTE:
• When any initialization is performed, all ID previ ously registered will be erased and all NATS mechanical
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-diagnos tic result on the CONSULT-III screen.
• In rare case, “CHAIN OF ECM-IMMU” might be stored as a self-diagnostic result during key registration pro-
cedure, even if the system is not malfunctioning.

to BL-158, "
Intelligent Key Battery Replacement" .
The engine cannot be started by all Intelligent Keys >> GO TO 3
The engine can be started by all Intelligent Keys >> GO TO 4
3.CHECK “KEY” WARNING LAMP ILLUMINATION
When pushing the ignition switch, check if “KEY” warning lamp in combination meter illuminates.
KEY warning lamp illuminates green >> Refer to BL-119, "
Trouble Diagnosis Symptom Chart" .
KEY warning lamp illuminates red >> Refer to BL-119, "
Trouble Diagnosis Symptom Chart" .
Does not illuminate >> Refer to BL-119, "
Trouble Diagnosis Symptom Chart" .
4.START ENGINE WITH MECHANICAL KEY
Check if the engine could be started by all registered mechanical keys.
