Symptom:
lFuel gauge indication is malfunction.
lLow-fuel warning lamp indication is irregular.
NOTE:
The following symptoms are not malfunction.
Fuel level sensor unit
lDepending on vehicle incline or driving circumstance, the fuel level in the tank varies, and the pointer may
fluctuate.
lIf the vehicle is fueled with the ignition switch ON, the pointer moves slowly.

Fuel Gauge Fluctuates, Indicates Wrong Value, or VariesEKS00L8V
1.CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving or at the instant of stopping.
Does the indication value vary only during driving or at the at the instant of stopping?
YES >> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis.
Fuel Gauge Does Not Move to Full positionEKS00L8W
1.QUESTION 1
Does it take a long time for the pointer to move to FULL position?
YES >> GO TO 2.
NO >> GO TO 3.
2.QUESTION 2
Was the vehicle fueled with the ignition switch ON?
YES >> Fuel the vehicle with the ignition switch OFF. Otherwise, it takes a long time to move to FULL posi-
tion because of the characteristic of the fuel gauge.
NO >> GO TO 3.
3.QUESTION 3

System DescriptionEKS00MHA
OIL PRESSURE WARNING LAMP
Oil Pressure Warning
Oil pressure warning lamp turns ON when engine oil pressure reducing abnormally.
lIPDM E/R reads oil pressure switch signal from oil pressure switch, and transmits the signal to combina-
tion meter with CAN communication.
lCombination meter turns oil pressure warning lamp ON with received oil pressure switch signal.
Oil Level Warning
If engine oil level is 15 mm below low level of oil level gauge, oil level warning is detected.
Oil pressure warning lamp blinks and “OIL Lo” is displayed on odo/trip meter display, when oil level warning is
detected.
Oil level warning is displayed during ignition switch ON for 30 seconds after engine oil maintenance informa-
tion is displayed for 5 seconds.
lCombination meter reads oil level signal from oil level sensor.
lWhen combination meter judges oil level warning condition by oil level signal, oil level warning is dis-
played.
NOTE:
lOil level is gauged when the driver door is open.
lOil level is not gauged for 5 minutes after ignition switch OFF to wait oil falling down from cylinder head.
