METER SYSTEM
INFORMATION DISPLAY : System Description
DESCRIPTION
- The combination meter inputs the information required to control the operation of information display by using the communication signals and others from each units and sensors.
- The combination meter incorporates a trip computer that displays the warning/information according to the information received from various units and sensors.
INSTANTANEOUS FUEL CONSUMPTION
The combination meter calculates instantaneous fuel consumption based on the following signals, and the calculated value is displayed on the information display.
NOTE:
- Instantaneous fuel consumption on the information display is updated approximately every 0.5 seconds.
- Instantaneous fuel consumption on the information display shows 0 l/100km (0 mpg) when vehicle speed is 0 km/h (0 MPH).
AVERAGE FUEL CONSUMPTION
The combination meter calculates average fuel consumption based on the following signals, and the calculated value is displayed on the information display.
NOTE:
- Average fuel consumption on the information display is updated approximately every 30 seconds.
- Soon after a reset or when the ignition switch is turned ON right after battery removal and installation, "---" is displayed until after a travel of 30 seconds and approximately 500 m (0.31 mile).
POSSIBLE DRIVING DISTANCE
The combination meter calculates possible driving distance based on the following signals, and the calculated value is displayed on the information display.
NOTE:
- Possible driving distance on the information display is updated approximately every 30 seconds.
- When the ignition switch is turned from OFF to ON, "---" is displayed until after a travel of approximately 500 m (0.31 mile).
- The indicated values may not match each other when refueling with the ignition switch ON. Normal Operating Condition.
AVERAGE VEHICLE SPEED
The combination meter calculates average vehicle speed based on the following signals, and the calculated value is displayed on the information display.
NOTE:
- Average vehicle speed on the information display is updated approximately every 30 seconds.
- Soon after a reset or when the ignition switch is turned ON right after battery removal and installation, "---" is displayed until after a 30 seconds.
AMBIENT AIR TEMPERATURE (FOR AUTO AIR CONDITIONING MODELS)
- The combination meter corrects an indicated temperature, based on various signals.
- The combination meter calculates ambient air temperature based on the following signals, and the calculated value is displayed on the information display.
Correction Process (Temperature indicated soon after the ignition switch ON)
A temperature indicated soon after the ignition switch is turned ON depends on the time from the ignition switch OFF to ON and a temperature detected by the ambient sensor.
When any condition described below is met, an ambient sensor-detected temperature is indicated.
- Time from the ignition switch OFF to ON ≥ Predetermined time
- Sensor-detected temperature less than Temperature at the last ignition switch OFF
When all the conditions described below are met, the temperature at the last ignition switch OFF is indicated.
- Time from the ignition switch OFF to ON less than Predetermined time
- Sensor-detected temperature ≥ Temperature at the last ignition switch OFF
Correction Process (Temperature at the Ignition switch ON)
A temperature indicated when the ignition switch is ON depends on a vehicle speed, an ambient sensor-detected temperature, and traveling time.
The temperature on the information display is corrected to an ambient sensor-detected temperature when the following condition is met.
- Ambient sensor-detected temperature less than Temperature on the information display
A temperature on the information display is not updated when the following condition is met.
- Ambient sensor-detected temperature ≥ Temperature on the information display
- Vehicle speed ≤ 20 km/h (12 MPH)
A temperature on the information display slowly rises to an ambient sensor-detected temperature when the following condition is met.
- Ambient sensor-detected temperature ≥ Temperature on the information display
- Vehicle speed ≥ 20 km/h (12 MPH)
A temperature on the information display rapidly rises to an ambient sensor-detected temperature when the following condition is met.
- Ambient sensor-detected temperature ≥; Temperature on the information display
- Vehicle speed ≥; 20 km/h (12 MPH)
- When driving more than set time
A/C Auto Amp. Connection Recognition
The combination meter judges from A/C auto amp. connection recognition signals that A/C auto amp. is connected and indicates an ambient air temperature on the information display.
NOTE:
- After an ignition switch is turned ON, "---" is displayed until after a 2.5 seconds.
- 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.
- After removal and installation of the battery and combination meter, an ambient sensor-detected temperature is indicated on the information display.
- Depending on engine heat or heat on the road surfaces, an ambient temperature may be indicated higher than actual one.
ICY WARNING (LOW AMBIENT AIR TEMPERATURE)
Based on an ambient temperature indication, the combination meter blinks the ambient temperature indication to warn the driver of a low ambient temperature.
Warning Operation Condition
Information display indication temperature ≤3�C (37�F)
Warning Cancel Condition
Warning is canceled if any of the following conditions is fulfilled.
- Information display indication temperature ≥ 4�C (39�F)
- 60 seconds after the start of warning indication
LOW FUEL WARNING
Combination meter indicates the low fuel warning judged by the fuel level sensor signal received from fuel level sensor unit.
Warning Operation Condition
Fuel level: Approx. 9.5 l (2-1/2 US gal, 2-1/8 Imp gal) or less [1.5 l(3/8 US gal, 3/8 Imp gal) fuel residues included].
MAINTENANCE (FOR CANADA)
The remaining distance from the set maintenance distance is displayed.
TRAVEL TIME (FOR CANADA)
The combination meter measures and displays travel time (ignition switch ON time).
