Codes
The ECM constantly monitors the engine by the
use of sensors on the engine. The ECM also uses
signals from the sensors to initiate sequential fuel
injection and make constant and instantaneous
changes to ignition timing, fuel delivery and throttle
position to maintain the engine's running condition
at its highest efficiency while at the same time
keeping exhaust emissions to a minimum. When a
sensor fails or returns signals that are outside of
set parameters, the ECM will store a fault code in
memory that relates to the appropriate sensor.
One or more faults will also be displayed on the
LCD screen located at the ground controls.
If a fault occurs that does not result in an engine
shutdown, the engine rpm will go into limp home
mode resulting in the loss of high rpm.

How to Retrieve
Active Engine Fault Codes for your specific engine
model. Use the Fault Code Chart to aid in
identifying the fault.
