Proper troubleshooting begins with an organized approach to the problem. Begin with investigation of the most
probable cause following the guidelines below.
Study the problem thoroughly before taking action:
• Did warning signs precede the problem?
• If so, what were they?
• What would they indicate?
• Is scheduled maintenance current on all parts and systems involved?
• Has similar trouble occurred before?
• What action was taken at that time?
• Are there any stored engine codes?
• Can engine be operated without further damage?
Check the most convenient items rst.
Don’t begin major work before checking all other possibilities.
Reconsider all known facts and clues before proceeding to more in-depth work. Correct the basic cause.
Remember, failure of a certain part may be caused by malfunction of another part or system.
