METER SYSTEM


INFORMATION DISPLAY : System Description


DESCRIPTION
- The combination meter retrieves the information required for controlling the operations of the information display from the communication signals from the unified meter and A/C amp., etc.
- The combination meter incorporates a trip computer that displays the warning / information according to the information received from various units.

PARKING BRAKE RELEASE WARNING
The combination meter indicates parking brake release warning judged with the vehicle speed signal received from the unified meter and A/C amp. by means of communication line and the parking brake switch signal from the parking brake switch.

Warning Operation Condition
Parking brake release warning is judged if all of the following conditions are fulfilled
- Vehicle speed is 7 km/h (4.3 MPH) or higher
- Parking brake switch ON

LOW FUEL WARNING
The combination meter indicates low fuel warning judged with the fuel level sensor signal received from the unified meter and A/C amp.

Warning Operation Condition
- Fuel level: Approx. 14 (3 - 5/7 US gal, 3 - 1/10 Imp gal) or less (TYPE A)
- Fuel level: Approx. 13.7 (3 - 5/8 US gal, 3 Imp gal) or less [3.1 (7/8 US gal, 5/8 Imp gal) fuel residues included.] (TYPE B)

NOTE:
To identify combination meter type, Application and ID.

LOW WASHER FLUID WARNING
The combination meter indicates low washer fluid warning judged with the signal from the washer level switch.

Warning Operation Condition
- Indicates the warning when it is in washer level switch ON condition for 180 seconds or more. Release the warning when it is in washer level switch OFF condition for 30 seconds or more.






LOW OUTSIDE TEMPERATURE WARNING
The combination meter indicates low outside temperature warning judged with the ambient sensor signal received from the unified meter and A/C amp. by means of communication line.

DOOR OPEN WARNING
The combination meter indicates door open warning judged with each door switch signal received from the unified meter and A/C amp. by means of communication line.

LOW TIRE PRESSURE WARNING
- The unified meter and A/C amp. receives remaining TPMS display signal from the BCM with CAN communication line.
- The unified meter and A/C amp. transmits remaining TPMS display signal to the combination meter with communication line.
- The combination meter indicates low tire pressure warning when receiving remaining TPMS display signal.
- The combination meter indicates low tire pressure warning judged with the TPMS display signal received from the unified meter and A/C amp.
For details, System Description.

FUEL FILLER CAP WARNING
- The unified meter and A/C amp. receives remaining fuel filler cap warning display signal from the ECM with
CAN communication line.
- The unified meter and A/C amp. transmits remaining fuel filler cap warning display signal to the combination meter with communication line.
- The combination meter indicates fuel filler cap warning when receiving remaining fuel filler cap warning display signal.
- The combination meter indicates fuel filler cap warning judged with the fuel filler cap warning display signal received from the unified meter and A/C amp.
For details, System Description (VQ35HR) or System Description (VK50VE).

INSTANTANEOUS FUEL CONSUMPTION
- The unified meter and A/C amp. receives the fuel consumption monitor signal from ECM and the vehicle speed signal from the ABS actuator and electric unit (control unit) with CAN communication line.
- The unified meter and A/C amp. calculates the instantaneous fuel consumption according to the fuel consumption monitor signal and the vehicle speed signal received with CAN communication line, and transmits it to the combination meter.

AVERAGE FUEL CONSUMPTION
- The unified meter and A/C amp. receives the fuel consumption monitor signal from ECM and the vehicle speed signal from the ABS actuator and electric unit (control unit) with CAN communication line.
- The unified meter and A/C amp. calculates the average fuel consumption according to the fuel consumption monitor signal and the vehicle speed signal received with CAN communication line, and transmits it to the combination meter.
- The average fuel consumption displayed on the information display is uploaded at approximately 30-second intervals.

NOTE:
When turning ON the ignition switch after triggering a reset or removing/installing the battery, "----" is indicated until 30 seconds/500 m (0.31 mile) of driving.

AVERAGE VEHICLE SPEED
- The unified meter and A/C amp. receives the vehicle speed signal from the ABS actuator and electric unit
(control unit) via CAN communication line.
- Measures the time during the ignition switch ON with the unified meter and A/C amp.
- The unified meter and A/C amp. calculates the average vehicle speed according to the above signals. These signals are transmitted to the combination meter with the communication line.
- The average vehicle speed displayed on the information display is uploaded at approximately 30-second intervals.

NOTE:
When turning ON the ignition switch after triggering a reset or removing/installing the battery, "----" is indicated until 30 seconds/500 m (0.31 mile) of driving.

TRAVEL TIME
Measures the time during the ignition switch ON with the unified meter and A/C amp, and transmits it to the combination meter by means of communication line.

TRAVEL DISTANCE
- The unified meter and A/C amp. transmits the vehicle speed signal from ABS actuator and electric unit (control unit) to the combination meter.
- The combination meter calculates the vehicle distance according to the vehicle speed signal. The vehicle distance is displayed.

POSSIBLE DRIVING DISTANCE
The unified meter and A/C amp. calculates possible driving distance according to the vehicle speed signal and fuel consumption monitor signal transmitted via CAN communication and the fuel level sensor signal transmitted from the fuel level sensor. These signals are transmitted to the combination meter with the communication line.

NOTE:
- When turning ON the ignition switch after removing/installing the battery, "----" is indicated until 30 seconds.
- The indicated values may not match each other when filling the fuel with the ignition switch ON. Information Display.

AMBIENT AIR TEMPERATURE
- The unified meter and A/C amp. receives the ambient sensor signal from the ambient sensor.
- The unified meter and A/C amp. calculates the ambient temperature according to the ambient sensor signal, and transmits it to the combination meter.
- The indicated temperature does not increase if the vehicle speed is less than 20 km/h (12 MPH).

NOTE:
- The ambient sensor input value that is displayed on "Data Monitor" of CONSULT-III is the value before the correction. It may not match the indicated temperature on the information display.
- Ambient temperature may be indicated higher than an actual temperature, depending on heat in the engine, a road surface temperature, and so on.
