- BCM
- Mechanical key
• NATS trouble diagnoses, system initialization and additional registration of other NATS mechanical key IDs
must be carried out using CONSULT-III hardware and CO NSULT-III NATS software. When NATS initializa-
tion has been completed, the ID of the inserted mechanical key can be displayed.
Regarding the procedures of NATS initialization and mec hanical key ID registration, refer to CONSULT-III
operation manual NATS.
SECURITY INDICATOR • Forewarns that the vehicle is equipped with NATS.
• Security indicator will not blink while the ignition knob is in ON or START state. NOTE:
Because security indicator is highly efficient, the battery is barely affected.
Condition of Secu rity Indicator
• When operating the ignition switch with Intelligent Key, se curity indicator lamp will turn off at once if ignition
switch is pressed and blinks when ignition switch is released.
• When operating the ignition switch with mechanical key security indicator will turn off at once if mechanical key is inserted into key cylinder and blinks when mechanical key is removed.
(Once the mechanical key is inserted into key cylinder, BCM will only perform the key ID verification with
mechanical key)
System Composition INFOID:0000000004305137
The function of the NATS consists of the following:
• Mechanical key
• NATS antenna amp. located in the ignition key cylinder
• BCM
• ECM (Engine control module)
• Security indicator
• Intelligent Key unit (if equipped)
NOTE:
The communication between ECM, BCM and/or Intelligent K ey unit uses the CAN communication sys-
tem.
ECM Re-communicating Function INFOID:0000000004305138
Performing the following procedure can automatically perform re-communication of ECM and BCM or Intelli-
gent Key unit, but only when the ECM has been replaced with a new one which has never been energized on-
board.
(In this step, initialization procedur e by CONSULT-III is not necessary)
NOTE:
• When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-III
Operation Manual NATS.

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.
