COMBINATION METER
 Speedometer, tachometer, fuel gauge, odo/trip meter and information display are controlled by the unified
meter control unit, which is built into the combination meter.
 Warning and indicator lamps are controlled by the unified meter control unit and by components connected
directly to the combination meter.
 Digital meter is adopted for odo/trip meter.*
*The record of the odometer is kept even if the battery cable is disconnected. The record of the trip meter is
erased when the battery cable is disconnected.
 Odo/trip meter segments can be checked in diagnosis mode.
 Meter/gauge can be checked in diagnosis mode.

OIL PRESSURE WARNING LAMP
 IPDM E/R reads the ON/OFF signals from the oil pressure switch and transmits the oil pressure switch sig-
nal to the combination meter via BCM with the CAN communication line.
 The combination meter turns the oil pressure warning lamp ON/OFF according to the oil pressure switch sig-
nal received via CAN communication.
Unit Description
Combination meterConverts the vehicle speed signal received from the ABS actuator and electric unit (control unit) via
CAN communication to mileage. Then, it displays the accumulated mileage using the odo/trip meter.

FUNCTION
The information display can indicate the following items.
 Engine oil change schedule
 Engine oil level
 Distance to empty
 Journey time
 Average fuel consumption
 Average speed
 Outside air temperature
ENGINE OIL CHANGE SCHEDULE
The remaining distance from the set engine oil change schedule is displayed.
OIL LEVEL
The combination meter judges the engine oil level based on the oil level sensor signal received from the oil
level sensor. If the oil level is sufficient, “Oil Good” is displayed for approximately 10 seconds. If the oil level is
low, “Oil Lo” blinks for approximately 30 seconds.
DISTANCE TO EMPTY
Unit Description
Combination meterTurns the oil pressure warning lamp ON/OFF according to the oil pressure switch signal received
from BCM by means of communication.
IPDM E/RReads 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.
Oil pressure switch Refer to MWI-31, "
Description".
BCMTransmits the oil pressure switch signal received from IPDM E/R to the combination meter via CAN
communication.

< FUNCTION DIAGNOSIS >
METER SYSTEM
The distance to empty indication provides the driver with an estimation of the distance that can be driven
before refueling. The distance to empty is calculated using signals from the fuel level sensor unit (fuel remain-
ing), ECM (fuel consumption) and vehicle speed signals from the ABS actuator and electric unit (control unit).
JOURNY TIME
The travel time since last reset is displayed.
AVERAGE FUEL CONSUMTION
Average fuel consumption indication is calculated using vehicle speed signals from the ABS actuator and elec-
tric unit (control unit) and fuel consumption information from the ECM.
AVERAGE SPEED
The average speed mode can be selected to display the average speed since last reset. The indications are
calculated using vehicle speed signals from the ABS actuator and electric unit (control unit).
OUTSIDE AIR TEMPERATURE
The combination meter indicates the outside air temperature calculated by the temperature signal received
from the ambient sensor.
The indicated temperature is not readily affected by engine heat. It changes only when one of the following
conditions is present.
 The temperature detected by the ambient sensor is lower than the indicated temperature
 The vehicle speed is greater than 20 km/h (13 MPH)
(This is to prevent the indicated temperature from being affected by engine heat during low-speed driving.)
 The ignition switch has been turned to the OFF position for more than 3.5 hours. (The engine is cold.)
When the ambient air temperature falls below 3°C (37°F), the display starts flashing. Approximately 20 sec-
onds later, only “°C” flashes.
NOTE:
On vehicles equipped with auto A/C, the ambient sensor signal is shared with the front air control. The combi-
nation meter is notified of the signal sharing via the auto A/C sense circuit.
