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. Note: All
fault codes are displayed, even if there has not been a fault. The fault codes scroll
across the three LED displays automatically.
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.
Error codes
Each error code consists of one set of digits. Each includes the letter "E" and
represents the type of error. Note: Only codes for those errors that have occurred
are displayed. The error codes are displayed as fixed characters—they do not
scroll across the LED displays automatically.
Error code example:
■ "E07" — the oil pressure sensor is or has been unplugged.
Viewing
Follow the procedure below to view the fault and error codes.
1. Connect the diagnostic tool. See section Connecting the Diagnostic Tool.
2. Enter the diagnostic mode of the ECM. See section Entering the ECM
Diagnostic Mode.
3. Use the buttons on the diagnostic tool to cycle through the codes. Pressing the
"A" button of the diagnostic tool advances through the codes. Pressing the "B"
button cycles through the codes in the opposite order.
4. The fault codes (F00 to F07) are displayed first followed by the error codes (E00
to E39). Pressing the buttons of the diagnostic tool cycles through the error
codes and back to the fault codes.
