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.
