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 platform 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 engine side turntable cover.
2 Locate the run/test toggle switch located on the
relay box cover.
3 Pull out the red Emergency Stop button to the
on position at the ground controls.
4 Hold the run/test toggle switch to the test
position and turn the key switch to the ground
controls position.
Result: The check engine light should turn on.
The check engine light should begin to blink.
Note: The check engine light will blink a "123" code
three times before blinking a fault code if one is
present.
4 - 56
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
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.
Note: Before the fault codes are displayed, the
check engine light will blink a code 123 times. After
the fault codes, the check engine light will blink a
code 123 three times again indicating the end of
the stored codes.
6 Refer to Section 5, Fault Codes for definition of
engine fault codes.
