Safety, Operation and Maintenance Manual
Electronic Fuel System will return the engine
to normal operation. The data reader can now
distinguish between active codes and those
stored in the historic code memory (inactive
codes). Inactive codes can only be viewed
using the data reader. The fault code recorded
in the ECM memory will remain until it is
erased by a technician.
The operator can check for active faults by
turning the ignition key switch to the 'OFF'
position, switching the diagnostic switch
'ON' and then turning the ignition key switch
to position '1'. If no active fault codes are
recorded, all three ('Stop', 'Warning' &
Maintenance) indicators will come on and
stay on. If active codes are recorded, all three
indicators will come on momentarily. The
yellow ('Warning') and red ('Stop') indicators
will begin to flash the code of the recorded
fault. The fault codes flash in the following
sequence: the yellow indicator flashes once,
then there is a pause where both indicators
are off. Then the numbers of the recorded fault
code flash in red. There is a pause between
each number. When the number is done, the
yellow indicator flashes again. e.g. yellow
flashes once - pause - red flashes twice -
pause - red flashes three times - pause - red
flashes five times - pause - yellow flashes
once, indicates fault code 235. The number
will repeat in the same sequence until the
system is advanced to the next active fault
code or the diagnostic switch is switched to
the 'OFF' position.
Refer to 'Electronic Fuel System Diagnostic
Codes' table for fault code descriptions.
