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.
Note: 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.
4 - 84
5 Continue to hold the run/test toggle switch in the
test position and count the blinks.
Note: 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.
6 Refer to Section 5, Fault Codes , for definition of
engine fault codes.
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.
