Fuel gauge system <Ref. to INSTRUMENT CLUSTER , Fuel Gauge System.>
DIAGNOSTIC PROCEDURE
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK DTC
. Read the DTC of the meter using the Subaru Select Monitor. |
Is DTC B1500 a current malfunction? | Go to step 2 . | Go to step 7 . |
2 CHECK COMBINATION METER
.
|
Is the operation of combination meter OK? | Go to step 3 . | Replace the combination meter. <Ref. to COMBINATION METER .> |
3 CHECK HARNESS
.
|
Is the resistance 10 Ω or less? | Go to step 4 . | Repair the open circuit of harness or replace harness. |
| 4 CHECK HARNESS
. Using the tester, measure the resistance between terminals. Connector & terminal (i10) No. 25 - Chassis ground: (i10) No. 37 - Chassis ground: |
Is the resistance 10 Ω or less? | Repair the short circuit of harness or replace harness. | Go to step 5 . |
| 5 CHECK FUEL SUB LEVEL SENSOR
. Check the fuel sub level sensor as a single part. <Ref. to INSPECTION , Fuel Sub Level Sensor.> <Ref. to INSPECTION , Fuel Sub Level Sensor.> |
Is the sensor normal? | Go to step 6 . | Replace the sensor. |
| 6 CHECK FUEL LEVEL SENSOR
. Check the fuel level sensor as a single part. <Ref. to INSPECTION , Fuel Level Sensor.> <Ref. to INSPECTION , Fuel Level Sensor.> |
Is the sensor normal? | Go to step 7 . | Replace the sensor. |
7 CHECK CONNECTOR
.
|
Is there poor contact of connector? | Repair or replace the poor contact of connector. | Go to step 8 . |
| 8 CHECK CURRENT DATA
. Using the Subaru Select Monitor, display the «Fuel sensing value» from {Current Data Display & Save}. |
Does the data display 10 - 570 Ω? | System is normal. | Replace the combination meter. <Ref. to COMBINATION METER .> |
