6.26.6 ECM Fault and Error Codes
Background
Machine fault and error codes are viewable on the three LED displays of the
ECM.
The tip-over fault is always viewable after engine start. To view all other fault
and error codes, the diagnostic mode of the ECM must be entered and the
diagnostic tool must be connected.
Fault codes
Each fault code consists of two sets of digits. The first set includes the letter
“F” and represents the type of fault. The second set represents the number
of times the fault has occurred or the time elapsed since the ECM has been
cleared. The fault codes scroll across the three LED displays automatically.
Note: All fault codes are displayed, even if there has not been a fault.
Fault code examples:
• F00-02—the roller has tipped over two times since the codes were
cleared.
• F06-0024—the starter has been engaged 24 times since the codes
were cleared
• F07-120.0 H—the roller has accumulated 120 hours since the codes
were cleared.
