General Troubleshooting Information
Troubleshooting engine problems can be difficult. An
engine wiring diagram is provided in this section to help
isolate electrical problems on power units using John
Deere wiring harness and instrument (gauge) panel.
Later in this section is a list of possible engine problems
that may be encountered accompanied by possible
causes and corrections. The illustrated diagrams and
troubleshooting information are of a general nature; final
design of the overall system for your engine application
may be different. See your engine distributor or servicing
dealer if you are in doubt.
A reliable program for troubleshooting engine problems
should include the following basic diagnostic thought
process:
•
Know the engine and all related systems.
•
Study the problem thoroughly.
•
Relate the symptoms to your knowledge of engine and
systems.
•
Diagnose the problem starting with the easiest things
first.
•
Double-check before beginning the disassembly.
•
Determine cause and make a thorough repair.
•
After making repairs, operate the engine under normal
conditions to verify that the problem and cause was
corrected.
NOTE: All engines have electronic control systems
which may send diagnostic trouble codes to signal
problems (see Diagnostic Trouble Codes (DTCs)
— Operation in the Troubleshooting Section).
1. If fault codes are present, perform the
suggested corrective actions.
2. If this does not correct the engine problem,
contact your servicing dealer.
3. If engine has problems but no fault codes
are displayed, see Engine Troubleshooting in
the Troubleshooting Section for problems
and solutions.
