NATS C/U Initialization and Key Registration Procedure

This procedure must be performed:

^ If the ECM has been replaced.
^ If the IMMU has been replaced.
^ If the ignition keys have been replaced or added to the system.

The NATS V 5.0 immobilizer system uses enhanced anti-theft functions which are password protected to prevent unauthorized access into the NATS registration procedure.

IMPORTANT:
This Electronic Key Registration Procedure for NATS V 5.0 is "unique" to the 2002 Q45. Do not use this procedure on any NATS vehicles other than the 2002 Q45.
