GENERAL INFORMATION

DIAGNOSIS & TESTING

Diagnostic Help

1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronic

modules through the data network.

2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.

3. If the Diagnostic Trouble Code (DTC) cannot be deleted, it is a current fault.

4. Use only a digital multimeter to perform voltage readings on electronic systems.

5. Refer to any Technical Bulletins that may apply to the failure.

6. Visually inspect the related wiring harness.

7. Inspect and clean all Engine Control Module (ECM) grounds that are related to the most current DTC.

8. If numerous trouble codes were set, use a wiring 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 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.

• Remove the Engine Control Module (ECM) from the troubled vehicle and install in a new vehicle and test. If

the DTC cannot be deleted, the ECM is malfunctioning. If the DTC can be deleted, return the ECM to the origi-
nal vehicle.

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-on⬙ accessories 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.

Diagnostic Tools

1. Diagnostic Scan Tool X-431

2. Digital Multimeter

3. Jumper Wire

Transaxle Control Module (TCM) Electrical Harness Test Tool

If using a TCM electrical harness test tool, you can diagnose the TCM harness while the TCM is still connected.

• Measure sensor and solenoid resistance (always measure resistance with the power off).

• Measure the signal voltage of the TCM (always measure voltage with the power on).

NOTE :
Using the TCM electrical harness test tool will help prevent electrical connector terminal damage.
