METER SYSTEM : System Description

COMBINATION METER

Combination Meter

• The combination meter monitors signals from switches, sensors and modules to control the following functions:

• Speedometer/Tachometer
• Shift position indicator
• Warning lamps
• Indicator lamps
• Meter illumination control
• Information display

• The combination meter has an integrated buzzer that is activated when it receives a signal from the BCM via CAN communication. Refer to WCS "WARNING CHIME SYSTEM : System Description" for further details.
• The combination meter includes a self diagnosis function.
• The combination meter can be diagnosed with CONSULT.

METER CONTROL FUNCTION LIST    

METER SYSTEM : Arrangement of Combination Meter 

METER SYSTEM : Fail-Safe

The combination meter activates the fail-safe control if CAN communication with each unit is malfunctioning.

SPEEDOMETER

SPEEDOMETER : System Description

SYSTEM DIAGRAM

DESCRIPTION

The ABS actuator and electric unit (control unit) receives each wheel speed sensor signal and provides a vehicle speed signal to the combination meter via CAN communication.

TACHOMETER

TACHOMETER : System Description

SYSTEM DIAGRAM

DESCRIPTION

The crank position sensor sends a crankshaft position signal to the ECM. The ECM provides an engine speed signal to the combination meter via CAN communication lines. The tachometer indicates engine speed in revolutions per minute (rpm).

SHIFT POSITION INDICATOR

SHIFT POSITION INDICATOR : System Diagram

SHIFT POSITION INDICATOR : System Description

DESCRIPTION

The combination meter receives the shift position signal from TCM via CAN communication, and displays the position of the shift indicator.

HIGH WATER TEMPERATURE WARNING LAMP

HIGH WATER TEMPERATURE WARNING LAMP : System Description

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 combination meter turning on the high temperature warning lamp.

SYSTEM DIAGRAM

OIL PRESSURE WARNING LAMP : System Description

DESCRIPTION

The combination meter turns the oil pressure warning lamp ON when receiving a signal from the ECM via CAN communication.

METER ILLUMINATION

METER ILLUMINATION : System Description

SYSTEM DIAGRAM

DESCRIPTION

Meter Illumination Control Function

Meter illumination control is enabled when the meter receives a signal from the BCM that the combination switch is in the 1st or 2nd position, the meter switches from Daytime mode to Nighttime mode.

Information display

INFORMATION DISPLAY : System Diagram

INFORMATION DISPLAY : System Description

DESCRIPTION

The combination meter receives signals from switches, sensors and modules for operating the following functions on the information display.

• Odo/trip meter
• Fuel gauge
• Trip computer
• Interrupt indication
• Meter illumination level
• Setting
• Low fuel warning
• Loose fuel cap warning

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.
