Symptom Troubleshooting
Use the following guidelines for troubleshooting:
- Understand the machine operation.
- Know if the symptom is a characteristic of normal operation or a failure.
- Use all available service literature to understand the machine systems and perform troubleshooting.
- Read the Systems Operation Manual to understand the machine systems.
- Understand machine system interactions.
- Understand the symptom.
- Speak with the operator about the symptom to acquire the following information:
- Machine performance prior to the failure.
- First occurrence of symptom.
- Operating conditions at the time of the failure.
- Sequence of events prior to the failure.
- Troubleshooting steps that have been taken.
- Inspect the machine for problems and unusual odors or noises.
- Research machine records for:
- Machine preventive maintenance history.
- Machine repair history.
- Related specific serial number service information.
- Speak with the operator about the symptom to acquire the following information:
- Duplicate the symptom.
- Operate the machine.
- Repeat the conditions that caused the failure.
- Check the gauges.
- Look for unusual indications.
- Operate the machine.
- Determine possible causes.
- Determine if an Electronic Control Module (ECM) has detected any faults.
- Use the information from the operator and your inspection.
- If there is more than one symptom, identify a common cause.
- Use the tests and procedures in this manual to verify the failure.
- Repair the failure.
- Test the system again to verify that the problem is resolved.
- Provide feedback to Caterpillar®.
Use the form in the Service Information System (SIS) web site or Component Based Troubleshooting (CBT) feedback to write a brief description about the symptom, testing, and repair. Include your phone number or e-mail address so you can be contacted. This feedback helps Caterpillar improve service information.
