How to Retrieve Engine Fault
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 fault LED's will illuminate on the display
located at the ground control box. The active fault
code will also be displayed on the LCD screen.
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.
Refer to Fault Codes Section, How to Retrieve
Active Engine Fault Codes for your specific model
of engine. Use the Fault Code Charts to aid in
identifying the fault.
