blown.

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect IPDM E/R connector.

3.

Check voltage between IPDM E/R harness connector and ground.

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> Repair harness or connector.

3.

CHECK GROUND CIRCUIT

Check continuity between IPDM E/R harness connectors and ground.

FUEL LEVEL SENSOR SIGNAL CIRCUIT

Description

INFOID:0000000000964398

The fuel level sensor unit and fuel pump (main) and the fuel level sensor unit (sub) detect the fuel level in the
fuel tank and transmit the fuel gauge signal to the unified meter and A/C amp.

Component Function Check

INFOID:0000000000964399

1.

CHECK UNIFIED METER AND A/C AMP. OUTPUT SIGNAL

Select the “Data Monitor” for the “METER/M&A” and compare the “FUEL METER” monitor value with the fuel
gauge reading on the combination meter.

Does monitor value match fuel gauge reading?

YES

>> INSPECTION END

NO

>> Replace combination meter.

Diagnosis Procedure

INFOID:0000000000964400

1.

CHECK UNIFIED METER AND A/C AMP. INPUT SIGNAL

1.

Turn ignition switch ON.

2.

Check voltage between unified meter and A/C amp. harness connector M67 terminal 42 and ground.

Does it match fuel gauge reading?

YES

>> GO TO 2.

NO

>> Replace the unified meter and A/C amp.

2.

CHECK FUEL LEVEL SENSOR (SUB) CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect unified meter and A/C amp. connector and fuel level sensor unit (sub) connector.

3.

Check continuity between unified meter and A/C amp. harness connector M67 terminal 42 and fuel level
sensor unit (sub) harness connector B21 terminal 1.

4.

Check continuity between unified meter and A/C amp. harness connector M67 terminal 42 and ground.

Is the inspection result normal?

OK

>> GO TO 3.

NG

>> Repair harness or connector.

< COMPONENT DIAGNOSIS >

FUEL LEVEL SENSOR SIGNAL CIRCUIT

1.

Disconnect fuel level sensor unit and fuel pump (main) connector.

2.

Check continuity between fuel level sensor unit (sub) harness connector B21 terminal 2 and fuel level
sensor unit and fuel pump (main) harness connector B22 terminal 2.

3.

Check continuity between fuel level sensor unit (sub) harness connector B22 terminal 2 and ground.

Is the inspection result normal?

OK

>> GO TO 4.

NG

>> Repair harness or connector.

4.

CHECK FUEL LEVEL SENSOR (MAIN) CIRCUIT

Check continuity between fuel level sensor unit and fuel pump (main) harness connector B22 terminal 5 and
unified meter and A/C amp. harness connector M67 terminal 58.

Is the inspection result normal?

OK

>> GO TO 5.

NG

>> Repair harness or connector.

5.

CHECK INSTALLATION CONDITION

Check fuel level sensor unit installation, and check whether the float arm interferes or binds with any of the
internal components in the fuel tank.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Install the fuel level sensor unit properly.

Component Inspection

INFOID:0000000000964401
