Information:

Which Generate This Code:This diagnostic code is associated with the circuit of the second output driver of the MSS ECM. This diagnostic code is recorded when the MSS is "armed" and the ECM detects voltage on the circuit for the output driver. This circuit is not used on all machines. Check for the presence of wires at contact 5 and contact 52 before you perform the procedure.The possible causes of this diagnostic code are listed below:
There is a problem with the software in the ECM.
There is a short to the +battery circuit in the wiring harness.
The ECM has failed. This is unlikely.Test Step 1. FLASH THE ECM.
Load the latest software file for the MSS into the ECM. Refer to Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program".
Clear the diagnostic code log.
Start the machine and operate the machine.
Determine if CID 1392 FMI 03 is present.Expected Result:CID 1392 FMI 03 is present.Results:
YES - CID 1392 FMI 03 is present. The software did not cause a problem. Go to Test Step 2.
NO - The diagnostic code was caused by a problem in the software. Stop.Test Step 2. TEST THE MACHINE HARNESS.
The key start switch must be in the OFF position.
Disconnect the machine harness from the MSS ECM.
Measure the voltage between pin 5 and pin 52 on the connector for the MSS ECM.Expected Result:Voltage is present.Results:
YES - Voltage is present between pin 5 and pin 52. The wiring harness is shorted.Repair: Repair the machine harness or replace the machine harness. Stop.
NO - Voltage is not present between pin 5 and pin 52. Go to Test Step 3.Test Step 3. CHECK THE ECM.
Remove pin 18 from the 70-pin connector of the MSS ECM.
Reconnect the MSS ECM to the system.
Use the ET to check the fault codes.Expected Result:CID 1392 FMI 03 is active.Results:
YES - CID 1392 FMI 03 is active.Repair: The MSS ECM has an internal failure. Replace the ECM. Refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace". Return the failed ECM to Caterpillar. Enclose a note with the following message: "The ECM has suffered an internal short to battery voltage." Stop.
NO - CID 1392 FMI 03 is NOT active.Repair: The MSS ECM has an internal failure. Replace the ECM. Refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace". Return the failed ECM to Caterpillar. Enclose a note with the following message: "The ECM has suffered a short to battery voltage in the driver #2 circuit." Stop.
