ODO/TRIP METER
The combination meter calculates mileage using the vehicle speed signal from the ABS actuator and electric
unit (control unit) and displays the mileage on the information display.
FUEL GAUGE
Control Outline
The fuel level sensor unit sends a variable resistor signal to the combination meter. The fuel gauge indicates
the approximate fuel level in the fuel tank.
Refuel Control
The unit detects the driver is refueling the vehicle and accelerates the fuel gauge segment movement if the
fuel level changes by 9 (2-3/8 US, 2 lmp gal) or more.
Lighting segment-resistance relationship
INTERRUPT INDICATION
The combination meter may interrupt the current information display with a warning, alert or maintenance
reminder on the information display, based on signals received from each unit and switch.
Low Fuel Warning
The low fuel warning turns ON when the fuel level in the fuel tank reaches approximately 6.3 (1-5/8 US gal,
1-3/8 Imp gal).
LOOSE FUEL CAP WARNING
The LOOSE FUEL CAP message will display in the information display when the fuel-filler cap is not tightened
correctly. The message will turn off as soon as the ECM detects the fuel-filler cap is properly tightened. The
ECM provides a loose fuel cap signal to the combination meter via CAN communication lines.
