Machine ECM
The following is a list of Diagnostic Trouble Codes (DTCs) that are associated with the configuration parameters of the ECM.
Table 1
Machine ECM (MID 39)
DTC Description System Response
268-2 Programmed Parameter Fault : Data erratic, intermittent, or incorrect The ECM has determined that a configuration parameter is not programmed. The ECM will display the parameter causing the problem on the Cat® Electronic Technician (Cat ET) Service Tool. The programming parameters identify conditions related to the programming of the ECM or a signal failure. A failure of the internal program of the ECM is associated with this diagnostic code as well. The fault messages displayed in Cat® Electronic Technician (Cat ET) Service Tool or the operator monitor include "programmed parameter fault" or other machine monitoring failures.Possible causes for an FMI 2 diagnostic code are:
The sales model and product identification are not programmed into the ECM.
The ECM is incorrect.Note: The correct sales model and product identification must be programmed when new software is flashed to the ECM.All the attachments for the machine are configured in the ECM. The ECM activates the 268-2 diagnostic code when an attachment is configured incorrectly.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. If a problem with a connection is found, correct the problem and verify that the diagnostic code is active before performing a troubleshooting procedure. For sensors powered via the fuse panel, check the condition of the appropriate fuse before beginning the 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 2.

FMI 2 Troubleshooting
Troubleshooting Test Steps Values Results
1. Verify The Configuration Of The Sales Model.
A. Use the Cat® Electronic Technician (Cat ET) Service Tool to verify that the ECM is configured to the default setting configuration.
The ECM has been configured correctly to the default setting configuration. OK - The ECM has been configured correctly to the default setting configuration.
Verify that the new configuration has corrected the problem before attempting to operate the machine.
Proceed to Test Step 3.
NOT OK - The ECM does not have the appropriate sales model and product identification.
Proceed to Test Step 2.
2. Configure The ECM.
A. Use Cat ET to reset the configuration to the default setting configuration. Reset the installation status to the correct type for the attachments that are installed on the machine.
The ECM is configured to the default setting configuration. OK - The ECM is configured to the default setting configuration.
Verify that the new configuration has corrected the problem before attempting to operate the machine.
Proceed to Test Step 3.
NOT OK - The ECM is not configured to the default setting configuration.
Repair: Repeat this procedure.
If the diagnostic code remains active or repeatedly activated and no cause can be found,
