GASKET 8N0967 - Caterpillar

This diagnostic code is recorded when the software location code for the ECM does not match the hardware location codes.Possible causes for an FMI 2 diagnostic code are:
The wrong software has been flashed into the ECM.
The machine harness has a short or a poor connection.
The machine harness has an open.
The ECM has failed. A failure of the ECM is unlikely.

LOC 1 GND J1 - 27
LOC 2 GND J1 - 28
LOC Enable GND J1 - 32 Note: The table above describes the connections of the machine location codes.Diagnostic Trouble Code Procedure
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. If a problem with a connection is found, correct the problem and verify that the diagnostic code is active before performing a troubleshooting procedure.
Identify the active FMI code associated with the components.
Determine which code is present and use the list below to determine which procedure to follow.
FMI 2 diagnostic code, proceed to Table 3.
