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 and
will turn on the Check Engine Light.
Note: Perform this procedure with the key switch in
the off position.
1 Open the ground controls side cover and locate
the run/test toggle switch on the side of the
ground control box.
2 Pull out the red Emergency Stop button to the
on position at both the ground and platform
controls.
3 Move and hold the run/test toggle switch to the
test position.
Result: The check engine light should turn on.
The check engine light should begin to blink.
4 Continue to hold the run/test toggle switch in the
test position and count the blinks.
5 - 8
Note: Before the fault codes are displayed, the
check engine light will blink a code 1-2-3 three
times. After the fault codes, the check engine light
will blink a code 1-2-3 three times again indicating
the end of the stored codes.
Note: If any fault codes are present, the ECM will
blink a three digit code three times for each code
stored in memory. It will blink the first digit of a
three digit code, pause, blink the second digit,
pause, and then blink the third digit. For example:
the check engine light blinks 5 consecutive times,
blinks 3 times and then 1 time. That would indicate
code 531.
Note: Once a fault code has been retrieved and the
repair has been completed, the ECM memory must
be reset to clear the fault code from the ECM. See
How to Clear Engine Fault Codes from the ECM.
