How to Retrieve Engine Fault
Codes
When a engine malfunction is detected by the
Electronic Control Module (ECM), a fault code is
recorded and the check engine light will illuminate
at the ground controls. Use the following procedure
to retrieve the engine fault code to determine the
engine malfunction.
Perform this procedure with the
key switch in the off position.
1 Open the ground controls side cover.
2 Pull out the red Emergency Stop button to the
on position at both the ground and platform
controls. Turn the key switch to ground
controls.
3 Quickly activate and release the start toggle
switch/button. Do not start the engine.
4 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.
5 Continue to hold the run/test toggle switch in the
test position and count the blinks.
Fault codes are two or three digits.
The check engine light will blink
the first digit of a two digit code
then will pause for 1.2 seconds
and then blink the second digit.
For example: the check engine
light blinks 5 consecutive times,
pauses for 1.2 seconds and then
blinks 1 time. That would indicate
code 51. The ECM is able to store
up to six individual fault codes.
There will be a 2.4 second pause
between codes.
Part No. 82259
6 Refer to Section 5 for definition of engine fault
codes.
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.
