The CID 0590diagnostic code is associated with the communication between the Advisor module and the Engine ECM via the Cat Data Link. The FMI 14 diagnostic code means that the Advisor module has not received enough parameters from the Engine ECM.
The Cat Data Link is an input and an output of all electronic control modules. The data link is designed to carry communications between all electronic control modules. The data link is not a visible component. The data link consists of internal control circuits and the connecting wire harness
- The software that is installed on the Engine ECM is incorrect.
- The software that is installed on the Advisor module is incorrect.
- A new ECM or Advisor module has been installed that is not the correct part number.
Test Step 1. VERIFY THE HARDWARE AND THE SOFTWARE PART NUMBERS
- Verify that the following information is correct:
- The part number of the installed software of the Engine ECM
- The part number of the installed software of the Advisor Module
- The part number of the Engine ECM
- The part number of the Advisor Module
Note: Contact the Technical Communicator in your dealership for the correct part numbers of the hardware and the correct part numbers for the configuration software.
- The part number of the installed software of the Engine ECM
Expected Result:
All hardware and software part numbers are correct.
Results:
- OK - All hardware and software part numbers are correct. Proceed to Test Step 2.
- NOT OK - All hardware and software part numbers are NOT correct.
Repair: Replace the hardware or software that is incorrect with the correct version. For flashing software, refer to Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program". For replacing ECM modules, refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace"
STOP
Test Step 2. CHECK THE STATUS OF THE DIAGNOSTIC CODE
- Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
- Check the status of the CID 0590 FMI 14 diagnostic code.
Expected Result:
The CID 0590 FMI 14 diagnostic code is not active.
Results:
- OK - The CID 0590 FMI 14 diagnostic code is not active. The diagnostic code does not exist at this time. The initial diagnostic code may have been caused by a start-up problem with one of the ECM controls.
Repair: Resume normal operation.
STOP
- NOT OK - The CID 0590 FMI 14 diagnostic code is active. the ECM that has activated the diagnostic code may have failed.
Repair: Verify that all possible causes of the diagnostic code have been investigated. Ensure that you have the latest version of software for your specific machine.Flash the Advisor Module and the Engine ECM with the latest version of software.Refer to the Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program" section of this manual for the correct procedure.If the diagnostic code is still active after flashing the latest software, contact the Technical Communicator at your dealership for a possible consultation with Caterpillar. This consultation may greatly reduce repair time. If the ECM needs to be replaced, refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace".
