KIT-BARREL 2802368 - Caterpillar

Illustration 1 g03326700The CID 1326 diagnostic code is associated with the ECM location code. The FMI 02 diagnostic code is recorded when the Implement ECM software location code does not match the hardware location codes.The probable cause of this diagnostic code is software. The wrong software has been flashed into the ECM.Note: Do not change the hard wired location code if you have flashed the incorrect software into the control.Note: To verify the correct location of the codes, use the Caterpillar Electronic Technician "(Cat ET)" "WinFlash". In the "WinFlash" screen, the “actual” location code and the ECM software part numbers are displayed for each ECM.Test Step 1. VERIFY HARDWARE, SOFTWARE, AND LOCATION CODE
Using "WinFlash" check that the latest software for each Implement ECM corresponds with the correct location code. Check with your dealer for the latest software part numbers. Expected Result:The latest Implement software is flashed on the ECM showing the location code of 2. The latest Implement software is flashed on the ECM showing the location code of 5.Results:
OK - Software and location codes are correct. Proceed to test step 2. The problem is likely an intermittent connection.
NOT OK - No ECM shows any of the location codes listed. There is a problem with the machine harness.Repair: Repair the machine harness or replace the machine harness.STOP
NOT OK - All part numbers are NOT correct. The installed ECM has the wrong part number or incorrect configuration software is installed.Repair: Flash the correct configuration software on the ECM with the displayed location code. Refer to Troubleshooting, "Electronic Control Module - Flash Program".Prior to replacing an ECM, always contact the Technical Communicator at your dealeship for a possible consultation with Caterpillar. This consultation may greatly reduce repair time. Refer to Troubleshooting, "Electronic Control Module (ECM) - Replace".STOPTest Step 2. INSPECT HARNESS CONNECTIONS
Turn the key start switch and the disconnect switch to the OFF position.
Inspect the harness connections that are related to the location codes. Make sure that the connectors are clean. Make sure that the connectors are tight.
Check for the proper mating of the connector.
Check all wires at the connector.
Check each wire for nicks. Check each wire for signs of abrasion in the insulation.
Check for moisture at the connector.
Check for dirty contacts or corroded contacts.
Check each pin and check each socket. Expected Result:The machine harness connectors are tight and the machine harness connectors are free of corrosion.Results:
OK - The machine harness connectors are tight and the machine harness connectors are free from corrosion. Proceed to test step 3.
NOT OK - One or more of the machine harness connectors are in need of repair.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK FOR SHORTS TO GROUND.
The disconnect switch and the key start switch remain in the OFF position.
Disconnect the machine harness connector from the Implement ECM.
At the machine harness for the Implement ECM, measure the resistance between the frame ground and the location code pins.
