INFORMATION DISPLAY : System DescriptionINFOID:0000000001374678
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.

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.

FUEL LEVEL SENSOR SIGNAL CIRCUIT
DescriptionINFOID:0000000001374693
The fuel level sensor unit and fuel pump detects the approximate fuel level in the fuel tank and transmits the
fuel level signal to the combination meter.
Component Function CheckINFOID:0000000001374694
1.COMBINATION METER INPUT SIGNAL
1. Select “METER/M&A” on CONSULT-III.
2. Using “FUEL METER” of “DATA MONITOR”, compare the value of DATA MONITOR with fuel gauge
pointer of combination meter.
Does the data monitor value approximately match the fuel gauge indication?
YES >> Inspection End.
NO >> Replace combination meter. Refer to MWI-94, "
Removal and Installation".
Diagnosis ProcedureINFOID:0000000001374695
1.CHECK HARNESS CONNECTOR
1. Turn ignition switch OFF.
2. Check combination meter and fuel level sensor unit terminals (meter-side and harness-side) for poor con-
nection.
Is the inspection result normal?
YES >> GO TO 2
NO >> Repair or replace terminals or connectors.
2.CHECK FUEL LEVEL SENSOR UNIT CIRCUIT
1. Disconnect combination meter connector and fuel level sensor
unit connector.
2. Check continuity between combination meter harness connector
(A) and fuel level sensor unit and fuel pump harness connector
(B).
3. Check continuity between combination meter harness connector
(A) and ground.
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair harness or connector.
