Downloaded from www.Manualslib.com manuals search engine Diagnostic Procedure
1.CHECK DTC
• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the IC.
• Turn ignition switch off, and wait a few seconds, then turn ignition switch on.
• With the scan tool, view DTCs in the IC.
Is DTC U0303 present?
Ye s>>Go to the next step.
No
>>The conditions that caused this DTC to set are not present at this time (See Intermittent DTC Trouble-
shooting in Section 15 Body & Accessories for more information).
2.CHECK FUEL LEVEL SENSOR ELECTRICAL CONNECTOR
• Turn ignition switch off.
• Disconnect the fuel level sensor and fuel pump
assembly electrical connector (3).
• Inspect the electrical connector for damage.
Is the electrical connector OK?
Ye s>>Go to the next step.
No
>>Repair or replace the electrical connector
as necessary.
3.CHECK FUEL LEVEL SENSOR REFERENCE VOLTAGE
• Turn ignition switch on.
• Check the fuel level sensor reference voltage
between the fuel level sensor connector B-032, ter-
minal 1 and ground.
• The voltage (less than 1 V) should exist.
Is there voltage present?
Ye s>>Go to step 5.
No
>>Go to the next step.

• Continuity should exist.
• Check the harness for a short to power.
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair or replace the fuel level sensor supply circuit as necessary.
5.CHECK FUEL LEVEL SENSOR GROUND CIRCUIT
• Using a 12 V test light connected to battery (+), probe fuel level sensor ground circuit.
Does the test light illuminate brightly?
Ye s>>Go to the next step.
No
>>Repair or replace the fuel level sensor ground circuit for an open.

• Turn ignition switch off.
• Check fuel level sensor as follows:
FUEL GAUGE POINTER
POSITION TANK (LITERS)SENDER RESISTANCE
(OHM) POINTER TOLERANCE
EMPTY 5283 ±3 °
RESERVE 11189 ±3 °
1/4 16.5 137±3 °
1/2 2889±3 °
3/4 39.5 62±3 °
FULL 5140±3 °
Is the check result normal?
Ye s>>Go to the next step.
No
>>Replace the fuel level sensor.
7.CHECK DTC
• With the X-431 scan tool, read IC DTCs.
• Refer to DTC Confirmation Procedure.
Is the DTC U0303 still present?
Ye s>>Replace the IC.
No
>>The system is now operating properly.
Reassemble the vehicle and verify the customers complaint is repaired.

Diagnostic Help
1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronicmodules through the class two serial data circuit.
2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.
3. If the DTC cannot be deleted, it is a current fault.
4. Use a digital multimeter to perform voltage readings on electronic systems.
5. Refer to any Technical Bulletins that issued.
6. Visually inspect the related electrical wiring harness.
7. Inspect and clean all Immobilizer control module grounds that are related to the DTC.
8. If numerous trouble codes were set, use the electrical schematic and look for any common ground circuits or voltage supply circuits that may apply to the DTC.
Intermittent DTC Troubleshooting
If the failure is intermittent, perform the following:
•Check for loose connectors.
• Look for any chafed, pierced, pinched, or partially broken wires.
• Monitor the scan tool data relative to this circuit.
• Wiggle the related electrical wiring harness and connectors while looking for an interrupted signal on the
affected circuit.
• If possible, try to duplicate the conditions under which the DTC set.
• Look for the data to change or for the DTC to reset during the wiggle test.
• Look for broken, bent, pushed out or corroded terminals.
• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age or foreign material.
• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.
Ground Inspection
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connec-
tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwanted
resistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically
affect an electronically controlled circuit. A poor or corroded ground can effect the circuit. Perform the following when
inspecting a ground connection:
1. Remove the ground bolt or screw.
2. Inspect all mating surface for tarnish, dirt, rust, etc.
3. Clean as required to assure good contact.
4. Reinstall bolt or screw securely.
5. Inspect for add-onaccessories which may be interfering with the ground circuit.
6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, make
sure no excess wire insulation has been crimped creating a bad ground.
