11BA3CHECK INPUT SIGNAL FOR ECM.
(USING VOLTAGE METER AND SUBARU
SELECT MONITOR.)
1) Turn ignition switch to ON. (Engine OFF)
2) Measure voltage between ECM connector and chassis
ground.
: Connector & terminal
(B84) No. 27 (+)—Chassis ground ( ):
Is the voltage more than 4.75 V?
: Go to step11BA4.
: Even if MIL lights up, the circuit has returned to a
normal condition at this time. A temporary poor
contact of the connector may be the cause.
NOTE:
In this case, repair the following:
Poor contact in fuel pump connector
Poor contact in combination meter connector
Poor contact in ECM connector
Poor contact in coupling connector (i3, B22, B97 and
R57)

11BA4
CHECK FUEL LEVEL SENSOR.
1) Turn ignition switch to OFF.
2) Remove fuel pump access hole lid located on the right
rear of luggage compartment floor.
B2M0935
3) Disconnect connector from fuel pump.
4) Measure resistance between connector terminals of
fuel pump.
: Terminals
No. 3—No. 5:
Is the resistance less than 100Ω?
: Go to step11BA5.
: Replace fuel sending unit.
G2M0863
11BA5
CHECK FUEL SUB LEVEL SENSOR.
1) Remove service hole cover located on the left rear of
luggage compartment floor.

2) Disconnect connector from fuel sub meter unit.
3) Measure resistance between connector terminals of
fuel sub meter unit.
: Terminals
No. 1—No. 2:
Is the resistance less than 100Ω?
: Go to step11BA6.
: Replace fuel sub meter unit.
B2M0937A
11BA6CHECK HARNESS BETWEEN FUEL
PUMP AND FUEL SUB METER UNIT
CONNECTOR.
Measure resistance of harness between fuel pump and fuel
sub meter unit connector.
: Connector & terminal
(R58) No. 3—(R59) No. 2:
Is the resistance less than 1Ω?
: Go to step11BA7.
: Repair open circuit in harness between fuel pump
and fuel sub meter unit connector.
B2M0938A
11BA7CHECK GROUND CIRCUIT OF FUEL
LEVEL SENSOR.
Measure resistance of harness between fuel pump con-
nector and chassis ground.
: Connector & terminal
(R58) No. 5—Chassis ground:
Is the resistance less than 5Ω?
: Go to step11BA8.
: Repair harness and connector.
NOTE:
In this case, repair the following:
Open circuit in harness between fuel pump connector
and chassis grounding terminal
Poor contact in fuel pump connector
Poor contact in coupling connectors (R57, B97 and B22)

11BA8CHECK HARNESS BETWEEN ECM AND
FUEL PUMP CONNECTOR.
1) Connect connector to fuel sub meter unit.
2) Turn ignition switch to ON.
3) Measure voltage between fuel pump connector and
chassis ground.
: Connector & terminal
(R58) No. 3 (+)—Chassis ground ( ):
Is the voltage less than 1 V?
: Repair harness and connector.
NOTE:
In this case, repair the following:
Open circuit in harness between fuel pump connector
and junction A on rear wiring harness
Poor contact in fuel sub meter unit connector
Poor contact in fuel pump connector
Poor contact in coupling connector (R57)
: Go to next step 4).
H2M1418B
4) Turn ignition switch to OFF.
5) Disconnect connector from ECM.
6) Turn ignition switch to ON.
7) Measure voltage between ECM connector and chassis
ground.
: Connector & terminal
(B84) No. 27 (+)—Chassis ground:
Is the voltage less than 1 V?
: Repair harness and connector.
NOTE:
In this case, repair the following:
Open circuit in harness between ECM connector and
junction A on rear wiring harness
Poor contact in coupling connector (B97)
: Repair connector.
NOTE:
In this case, repair the following:
Poor contact in fuel pump connector
Poor contact in fuel sub meter unit
Poor contact in ECM connector
