NONE.
10
Engine immobilizer
ENGINE IMMOBI
INACTIVE
Indicates the status of the immo-
bilizer system.
• INACTIVE: The ECM has rec-
ognized the immobilizer code
transmitted by the Intelligent
Key unit or BCM.
• ACTIVE: The ECM does not
recognize the immobilizer
code transmitted by the Intelli-
gent Key unit or BCM.
If ACTIVE, perform the trouble diag-
nosis for NATS.

Vehicle speed
VEHICLE SPEED
0 km/h (mph)
Indicates the vehicle speed in
km/h (mph). This parameter is
transmitted by the “ABS actuator
and electric unit (control unit)” or
combination meter via CAN
communication line.
Perform the trouble diagnosis for
CAN communication line. Perform
the trouble diagnosis for “ABS actu-
ator and electric unit (control unit)” or
combination meter.
