CONTROL OUTLINE

• The unified meter and A/C amp. reads the fuel level sensor signal from the fuel gauge unit and transmits it to

the combination meter with the communication line.

• The combination meter indicates the fuel level on the fuel gauge according to the received fuel level sensor

signal.

REFUEL CONTROL

The unit judges that the driver is refueling the vehicle and accelerates the fuel gauge needle movement if the
fuel level changes by 15   (4 US gal, 3-3/10 Imp gal) or more.

Unified meter and A/C amp.

Transmits the engine coolant temperature signal received from ECM with CAN communication 
line to the combination meter by means of communication line.

ECM

Transmits the engine coolant temperature signal to the unified meter and A/C amp. with CAN 
communication line.

ODO/TRIP METER : System Description

INFOID:0000000000964347

• The unified meter and A/C amp. transmits the vehicle speed signal from ABS actuator and electric unit (con-

trol unit) to the combination meter.

• The combination meter calculates the vehicle distance according to the vehicle speed signal. The vehicle

distance is displayed.
