ENGINE OIL PRESSURE GAUGE : System Description

INFOID:0000000005260345

The engine oil pressure gauge indicates whether the engine oil pressure is low or normal.

The oil pressure gauge is controlled by the IPDM E/R. The IPDM E/R reads the ON/OFF signals from the oil

pressure switch and transmits the oil pressure switch signal to the combination meter via BCM with the CAN

communication line. The oil pressure gauge displays a low or normal indication according to the oil pressure

switch signal received via CAN communication.

TRIP COMPUTER : System Description

INFOID:0000000005260365

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.
