THE FUEL GAUGE POINTER DOES NOT MOVE TO "F" WHEN REFUELING

THE FUEL GAUGE POINTER DOES NOT MOVE TO "F" WHEN REFUEL-
ING

Description

INFOID:0000000009480391

The fuel gauge needle will not move to “F” position when refueling.

Diagnosis Procedure

INFOID:0000000009480392

1.

OBSERVE FUEL GAUGE

Does it take a long time for the pointer to move to FULL position?
YES or NO

YES

>> GO TO 2

NO

>> GO TO 3

2.

IDENTIFY FUELING CONDITION

Was the vehicle fueled with the ignition switch ON?
YES or NO

YES

>> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time to move

to FULL position because of the characteristic of the fuel gauge.

NO

>> GO TO 3

3.

OBSERVE VEHICLE POSITION

Is the vehicle parked on an incline?
YES or NO

YES

>> Check the fuel level indication with vehicle on a level surface.

NO

>> GO TO 4

4.

OBSERVE FUEL GAUGE POINTER

During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES or NO

YES

>> Check the components. Refer to

MWI-35, "Component Inspection"

.

NO

>> The float arm may interfere or bind with any of the components in the fuel tank.

THE OIL PRESSURE WARNING LAMP DOES NOT TURN ON

Description

INFOID:0000000009480393

The oil pressure warning lamp stays off when the ignition switch is turned ON.

Diagnosis Procedure

INFOID:0000000009480394

1.

CHECK OIL PRESSURE WARNING LAMP

Perform IPDM E/R auto active test. Refer to

PCS-9, "Diagnosis Description"

.

Is oil pressure warning lamp illuminated?

YES

>> GO TO 2

NO

>> Replace combination meter. Refer to

MWI-90, "Removal and Installation"

.

2.

CHECK OIL PRESSURE SWITCH SIGNAL CIRCUIT

Check the oil pressure switch signal circuit. Refer to

MWI-37, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Repair harness or connector.

3.

CHECK OIL PRESSURE SWITCH UNIT

Perform a unit check for the oil pressure switch. Refer to

MWI-37, "Component Inspection"

.

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to

PCS-28, "Removal and Installation of IPDM E/R"

.

NO

>> Replace oil pressure switch.

THE OIL PRESSURE WARNING LAMP DOES NOT TURN OFF

THE OIL PRESSURE WARNING LAMP DOES NOT TURN OFF

Description

INFOID:0000000009480395

The oil pressure warning lamp remains illuminated while the engine is running (normal oil pressure).

Diagnosis Procedure

INFOID:0000000009480396

Regarding Wiring Diagram information, refer to

MWI-65, "Wiring Diagram"

.

1.

CHECK OIL PRESSURE WARNING LAMP

Perform IPDM E/R auto active test. Refer to

PCS-9, "Diagnosis Description"

.

Is oil pressure warning lamp illuminated?

YES

>> GO TO 2

NO

>> Replace combination meter. Refer to

MWI-90, "Removal and Installation"

.

2.

CHECK IPDM E/R OUTPUT VOLTAGE

1. Turn ignition switch OFF.

2. Disconnect the oil pressure switch connector.

3. Turn ignition switch ON.

4. Check voltage between the oil pressure switch harness connec-

tor E208 (VQ40DE) or F4 (QR25DE) terminal 1 and ground.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> GO TO 4

3.

CHECK OIL PRESSURE SWITCH

Perform a unit check for the oil pressure switch. Refer to

MWI-37, "Component Inspection"

.

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to

PCS-28, "Removal and Installation of IPDM E/R"

.

NO

>> Replace oil pressure switch.

4.

CHECK OIL PRESSURE SWITCH SIGNAL CIRCUIT

Check the oil pressure switch signal circuit. Refer to

MWI-37, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to

PCS-28, "Removal and Installation of IPDM E/R"

.

NO

>> Repair harness or connector.

COMPASS
COMPASS : Description

INFOID:0000000009480397

COMPASS

• The electronic compass is highly protected from changes in most magnetic fields. However, some large

changes in magnetic fields can affect it. Some examples are (but not limited to): high tension power lines,

large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While

this does not happen very often, it is possible.

• During normal operation, the Compass Mirror will continuously update the compass calibration to adjust for

gradual changes in the vehicle's magnetic "remnant" field. If the vehicle is subjected to high magnetic influ-

ences, the compass may appear to indicate false headings, become locked, or appear that it is unable to be

calibrated. If this occurs, perform the calibration procedure.

• If at any time the compass continually displays the incorrect direction or the reading is erratic or locked, ver-

ify the correct zone variance.

Symptom Chart

Symptom

Cause

Solution / Reference

The compass display reads "C".

• Compass is not calibrated.
• Incorrect zone variance setting.
• Large change in magnetic field (Steel

bridges, subways, concentrations of
metal, car washes, etc.)

• Compass was calibrated incorrectly or

in the presence of a strong magnetic
field.

Perform Calibration. Refer to

MWI-23,

"Description"

.

Compass shows the wrong direction.

Compass does not change direction ap-
pears "Locked".

Compass does not show all the directions,
one or more is missing.

The compass was calibrated but it "loses"
calibration.

On long trips the compass shows the
wrong direction.

Perform Zone Variation Setting if correct
reading is desired in that location. Refer to

MWI-23, "Description"

.
