HIGH WATER TEMPERATURE WARNING LAMP : System Description

INFOID:0000000009266572

SYSTEM DIAGRAM

DESCRIPTION

The ECM monitors the engine coolant temperature from the engine coolant temperature sensor. When the

coolant temperature is above the specified value, the ECM sends a CAN communication signal to the combi-

nation meter turning on the high temperature warning lamp.

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.
