How to Retrieve Engine Fault
Codes
When an engine malfunction is detected by the
Electronic Control Module (ECM), a fault code is
recorded and the check engine light will turn on at
the ground controls. Special equipment is required
to retrieve fault codes stored within the ECM.
Contact Genie Industries Service Department for
assistance in retrieving fault codes.
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 Quickly activate and release the start toggle
switch/button. Do not start the engine.
(before serial no. 7597)
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 - 28
5 Continue to hold the run/test toggle switch in the
test position and count the blinks.
Note: If any fault codes are present, the ECM will
use the check engine light to blink a three digit
code.
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. There will be
a longer 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.
