Fault codes appear when an issue is detected within your heavy-duty equipment and clearing them without addressing the problem can often lead to recurring issues.
Below are some examples to consider before clearing a fault:
- Check for recalls or TSBs
Determine if the component or equipment manufacturer has put out a technical service bulletin (TSB) or recall related to the affected system. Technicians can save valuable time by following the manufacturer’s instructions before attempting a manual diagnosis.
- Review work orders/log files
Look at work orders and diagnostic log files to determine if any previous repair work could have led to the current fault(s).
- Perform a visual inspection
Ensure that you pair the electronic diagnostic scan with a comprehensive visual inspection. Visually inspect your equipment from end to end, paying special attention to areas producing the fault code(s), looking for damaged wires, corrosion, or other abnormalities that can produce a fault.
- Document your findings
Document your findings and keep detailed records of your troubleshooting process so you and your fellow technicians can efficiently repair the issue if a similar problem occurs in the future.
- Address the root cause
Utilize effective troubleshooting procedures to find the root cause of the issue to perform repairs that fix the problem rather than temporarily solving it.
