NOTE:
+When any initialization is performed, all ID previously reg-
istered 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 may show ªDIFFERENCE OF KEYº or
ªLOCK MODEº as a self-diagnostic result on the CONSULT-II
screen.
+When initialization is performed for RHD models for Europe,
security indicator will flash six times to demonstrate recognition
of the dongle unit ID.
+In rare case, ªCHAIN OF ECM-IMMUº might be stored as a
self-diagnostic result during key registration procedure, even if
the system is not malfunctioning.

(EL-349)Engine trouble data and NATS
trouble data have been detected
in ECMÐ
*: When NATS detects trouble, the security indicator lights up while ignition key is in the ªONº position.
*: When the vehicle is equipped with a dongle unit (RHD models for Europe), the security indicator blinks 6 times just after the ignition
switch is turned to ON. Then the security indicator lights up while the ignition key is in the ªONº position.
