Information:
Possible causes for an FMI 9 diagnostic code are:
Terminating resistors on the J1939 Data Link are faulty.
An open or a poor connection in the circuit.
A short in the circuit.
An ECM or smart device is not powering up or powering down properly.
Lack of key switch input to an ECM or smart device.
Excessive noise on the circuit.
Software configuration mismatch.
One of the ECM modules has failed. This condition is unlikely.Possible causes for an FMI 14 diagnostic code are:
Incorrect software is installed.
Incompatible software may be installed.
Interference across the data link wires.
A control module has failed. This situation is unlikely.

Schematic of the CAN Datalink
Note: The diagram above is a simplified schematic of the CAN Datalink connections. The schematic is electrically correct. However, not all of the possible harness connectors are shown. Refer to the latest revision of Electrical Schematic, UENR1138 for the complete schematic.Diagnostic Trouble Code Procedure
Note: Prior to beginning this procedure, inspect the harness connectors that are involved in this circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure, and in good condition. Check the wiring for pinch points or abrasions. Look for and repair areas that indicate wires are exposed. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing a troubleshooting procedure.
Table 2
Troubleshooting Test Steps Values Results
1. Identify The Active FMI Code Associated With The Data Link Code present FMI 9, proceed to Test Step 2.
FMI 14, proceed to Test Step 7.
Begin Process For FMI 9 Troubleshooting HERE
2. Check For Other Codes
A. Check for similar diagnostic codes that are logged against other electronic control modules.
B. If a similar diagnostic code is found, exit this test and perform the corresponding procedure for the other diagnostic code that is shown.
Another diagnostic code is showing. OK - Exit this procedure and perform the diagnostic procedure for the diagnostic codes that are shown.
Proceed to Test Step 8.
NOT OK - There are no other related diagnostic codes.
Proceed to Test Step 3.
3. Inspect The Harness Connections
A. Turn key start switch and disconnect switch OFF.
B. Inspect all harness connections related to the data link. Make sure that the connectors are clean and tight.
The machine harness is correct. OK - The machine harness is correct.
Proceed to Test Step 4.
NOT OK - The machine harness is not correct.
