TRIP COMPUTER

TRIP COMPUTER : System Diagram

INFOID:0000000003935340

TRIP COMPUTER : System Description

INFOID:0000000003935341

FUNCTION

The trip computer can indicate the following items.
• DTE (distance to empty)
• Trip distance
• Trip time
• Average fuel consumption
• Average vehicle speed

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 the ABS actuator and electric unit (vehicle speed). The indication will be refreshed every 30 seconds.
When fuel remaining is less than approximately 11.6  (3 1/8 US gal, 2 1/2 Imp gal), the indication will blink as
a warning. If the fuel remaining is less than approximately 9.6  (2 1/2 US gal, 2 1/8 Imp gal), 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 0.3 miles (0.5 km).

TRIP DISTANCE

Trip distance is calculated by signal from the ABS actuator and electric unit (vehicle speed). 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 ABS actuator and electric unit (vehicle
speed) 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

Refer to Owner's Manual for trip computer operating instructions.
