This test is reserved for identifying conditions related to the programming of the ECM or a signal failure. In this instance the ECM is receiving information that is erratic, intermittent, or incorrect. A failure of the internal program of the ECM is associated with the test as well. The fault messages displayed in Cat ET or via the Information Display include "programmed parameter fault" or some type of machine monitoring failure.
The following diagnostic trouble codes (DTC) are associated with the configuration parameters for the Implement ECM.
| Implement ECM (MID 82) | ||
|---|---|---|
| DTC | Description | System Response |
| 268-2 | Programmed Parameter Fault: Data Erratic, Intermittent, or Incorrect | The Implement ECM has determined that a configuration parameter is not programmed. The ECM will display the parameter causing the problem via Cat® ET. |
Possible causes of an FMI 2 diagnostic code are:
- The sales model and product identification need programming.
- The ECM is incorrect.
Diagnostic Trouble Code Procedure
Note: Prior to beginning this procedure, inspect the harness connectors that are involved in the 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 this diagnostic code is active before performing this procedure.
| Troubleshooting Test Steps | Values | Results |
|---|---|---|
| 1. Verify The Configuration Of The Sales Model. A. Use the Cat ® Electronic Technician (Cat ET) 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. STOP 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. STOP 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, flash the ECM with the latest version of software. Ensure that you have the latest version of software for your specific machine and ECM. Refer to the Troubleshooting, " ECM Software - Install " section of this manual for the correct procedure. If the problem is still present after flashing the latest software to the ECM, contact the Technical Communicator at your dealership for a possible consultation with Caterpillar. STOP |
