Diagnostic and Event Flash Codes
Flash codes are used to represent diagnostic codes in the electronic system in order to alert
the operator that a problem exists.
Event codes refer to engine operating conditions and usually indicate a mechanical rather than
an electrical system problem.
NOTE: Flash codes can represent more than one failure mode indicator.
Use the engine manufacturers service tool to view failure modes.
