ERROR CODES
On rare occasions the engine may experience abnormal operation conditions and shut down. Upon shutdown the
amber light in the upper right corner of the instrument panel will repeatedly flash an error code to help you
determine the root cause of the shutdown. Double-digit numbers are flashed one digit at a time, (i.e. “12” would
be shown as “Flash”, pause, “Flash”, “Flash”). The codes are listed below for your convenience.
