• ECM converses a signal from engine coolant temperature sensor to engine coolant temperature signal, and

transmits to unified meter and A/C amp. with CAN communication line.

• Unified meter and A/C amp. transmits engine coolant temperature signal to combination meter with commu-

nication line.

• Combination meter converses engine coolant temperature signal to the angle signal, and commands to

engine coolant temperature gauge.

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 combination meter accelerates the fuel gauge segment if the all conditions listed below are met, or the
ignition switch is ON from OFF.
• Ignition switch is ON position.
• The vehicle is not moving.
• The fuel level change by 15 (4 US gal, 3-3/10 Imp gal) or more.
