BOARD COMPUTER / FOR A/T MODELS
System Description
FUNCTION
The board computer can indicate the following items.
-
Outside air temperature
-
DTE (distance to empty)
-
Trip distance
-
Trip time
-
Average fuel consumption
-
Average vehicle speed
OUTSIDE AIR TEMPERATURE INDICATION
The outside air temperature indication is displayed while the ignition switch is in the ON position.
Signal is supplied
-
through ambient sensor terminal 1
-
to combination meter (board computer) terminal 13.
Indication range is between -30 and 55 °C (-22 and 131 °F). When outside temperature is less than -30 °C (-22 °F), display shows ICY. When outside
temperature is more than 55 °C (131 °F), indication will be blank. When outside temperature is less than 3 °C (37 °F) continuously, display will blink as
a warning. In this case, the display will change to the outside air temperature mode even though the display is showing a different mode. The indicated
temperature is not affected by engine heat. It changes only when one of the following conditions exists.
-
When vehicle speed is more than 20 km/h (12 MPH).
-
The ignition switch has been turned OFF for more than 3.5 hours.
-
When outside air temperature is less than the indicated temperature.
DTE (DISTANCE TO EMPTY) INDICATION
The range indication provides the driver with an estimation of the distance that can be driven before refueling. The range is calculated by signals from
the fuel level sensor unit (fuel remaining), ECM (fuel consumption) and vehicle speed sensor. The indication will be refreshed every 30 seconds. When
fuel remaining is less than approximately 10 l (10 5/8 US quarts, 8 3/4 Imp quarts), the indication will blink as a warning. If the fuel remaining is less
than approximately 8 l (8 1/2 US quarts, 7 Imp quarts), the indication will show "---". In this case, the display will change to the DTE mode even
though the display is showing a different mode. When the battery is disconnected and reconnected, DTE mode will display "---" until the vehicle is
driven 500 miles (804.5 km).
TRIP DISTANCE
Trip distance is calculated by signal from the vehicle speed sensor. If trip distance is reset, trip time will be reset at the same time.
TRIP TIME
Trip time displays cumulative ignition switch ON time. If trip time is reset, trip distance will be reset at the same time.
AVERAGE FUEL CONSUMPTION
Average fuel consumption indication is calculated by signals from the vehicle speed sensor and the ECM (fuel consumption). The indication will be
refreshed every 30 seconds.
AVERAGE VEHICLE SPEED
Average vehicle speed indication is calculated by running distance and running time. The indication will be refreshed every 30 seconds. If average
vehicle speed is reset, average fuel consumption will be reset at the same time. After resetting, the display will show "---" for 30 seconds.
HOW TO CHANGE/RESET INDICATION
Indication can be changed in the following order by momentarily depressing the board computer switch or the board computer steering switch.
Outside air temperature -> DTE -> Trip distance -> Trip time -> Average fuel consumption -> Average vehicle speed.
Holding the switch for more than 0.8 second will reset the indication of the currently displayed mode (trip distance, trip time, average vehicle speed or
