FMI 13 Troubleshooting
Troubleshooting Test Steps Values Results
1. Check the Calibration
A. Perform the calibration procedure for the sensor. Refer to the calibration procedure in Testing and Adjusting, KENR6296 for this machine.
B. Observe the status of the diagnostic code.
The code is no longer active. OK -The FMI 13 is no longer active. The calibration corrected the condition that caused the diagnostic code
Proceed to Test Step 2.
NOT OK -The FMI 13 Code is active. The diagnostic code has not been corrected. Verify that the correct software has been flashed into the ECM, or that the correct ECM is installed on the machine. Then repeat the calibration
Proceed to Test Step 2.
2. Check If The Diagnostic Code Remains
A. Turn the key start switch and the disconnect switch ON.
B. Clear all diagnostic codes.
C. Operate the machine.
D. Stop the machine and engage the safety lock lever.
E. Check if the diagnostic code is active.
The diagnostic code is no longer present. OK - The diagnostic code does not exist currently. The initial diagnostic code may have been caused by poor electrical connection or short at one of the harness connections. Resume machine operation.
STOP.
NOT OK - The diagnostic trouble code has not been corrected. If the diagnostic code has not been corrected after performing the procedure a second time, the ECM may require replacement.
Prior to replacing the ECM, always contact the Technical Communicator at your dealership for possible consultation with Caterpillar. This consultation may effect repair time.
Follow the steps in Troubleshooting, "ECM - Replace" if the ECM needs to be replaced.
STOP.

Troubleshooting Test Steps Values Results
1. Check The Fuses For The ECM Modules On The CAN Data Link Circuit
A. Turn the key start switch and disconnect switch to the OFF position.
B. Refer to the full system schematic to determine if the suspected circuit has an in line fuse.
C. If applicable, check the continuity of the fuse related to the active diagnostic code.
The fuses are closed (or intact). OK - The fuses have not failed.
Proceed to Test Step 2.
NOT OK - One or more of the fuses have failed.
Repair: Replace all open fuses.
STOP
2. Check The Software
A. Use Cat ® Electronic Technician (Cat ET) to verify that the software versions for the data link modules are correct and compatible.
The proper software is installed. OK - The proper software is installed.
Proceed to Test Step 3.
Repair: Flash the proper software to the appropriate ECM module. Cycle the key start switch to initialize the software. Ensure that the diagnostic code is no longer active.
STOP
3. Check For Power To The Key Reader
A. With the key start switch in the ON position, check for system voltage between contact 3 and contact 4 of the Key Reader.
The voltage that is measured closely matches system voltage. OK - The voltage that is measured is approximately system voltage. The voltage is correct.
STOP
NOT OK - System voltage is NOT present. The wiring harness has failed.
Repair: Check the wiring harness for signs of damage. Repair the machine harness or replace the machine harness.
STOP
