Clearing Service Monitor Lamp
Perform the following to clear the service monitor lamp:1. Turn the ignition switch off.
2. Press down and hold the Mode switch.
3. Turn the ignition switch on.
4. Release the Mode switch.
5. Press the Mode switch and the Clock switch simultaneously within 30 seconds and hold less than 2 seconds to clear the mileage maintenance identification.
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 Instrument Cluster (IC) 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.

DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on and record and erase DTC.
• Start engine and warm it up to the normal operating temperature.
• Select view DTC and data stream.
• If the DTC is detected, the condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 15 Body & Accessories for more information).
NOTE :
Before performing any DTC diagnostic procedures, verify the IC power and ground circuits are properly connected.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.

1.CHECK DTC
• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the IC module.
• Turn ignition switch off, and wait a few seconds, then turn ignition switch on.
• With the scan tool, view active DTCs in the IC module.
Is DTC U040F 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 COOLANT TEMPERATURE SENSOR (FOR INSTRUMENT CLUSTER) ELECTRICAL CONNECTOR
• Turn ignition switch off.
• Disconnect the coolant temperature sensor (for
instrument cluster) (1) electrical connector E-084.
• Inspect the electrical connector for damage.
Is the electrical connector OK?
Ye s>>Go to the next step.
