Engine

MOTOR

RUNNING
Indicates the current status of 
the engine.
• STOPPED
• STARTER
• ACTIVATED
• RUNNING

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.

11

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.
