GASKET KIT-V 6V2237 - Caterpillar

This diagnostic code is recorded when the transmission ECM has dropped off the Cat Data Link 10 times within a ten minute period for more than five seconds. The event is active until communication is reliable for more than ten minutes. System Response:This failure results in events that are logged against an ECM that can not be explained. The "VIMS ECM" cannot communicate with this ECM or the ECM appears to work intermittently. Test Step 1. VERIFY THE HARDWARE AND THE SOFTWARE PART NUMBERS.
Verify that the following information is correct:
The part number of the "VIMS onboard flash software"
The part number of the "transmission ECM flash software"
The part number of the "VIMS ECM"
The part number of the transmission ECM Note: Consult the Business Unit that produces the product for the correct part numbers of the configuration software.Expected Result:All part numbers are correct. Results:
OK - All part numbers are correct. Proceed to test step 2.
NOT OK - All part numbers are NOT correct. Repair: The installed "VIMS ECM" or the transmission ECM has the wrong part number or the incorrect flash software is installed. Replace the incorrect "VIMS ECM" or the transmission ECM with a module that has the correct part number. Flash the correct software. See the Testing and Adjusting, "Electronic Control Module (ECM) - Flash Programming" section of this manual.STOPTest Step 2. INSPECT THE HARNESS CONNECTIONS.
Turn the disconnect switch to the OFF position.
Inspect all harness connections that are related to the Cat Data Link. Make sure that the connectors are clean and tight.
Check the connectors for proper mating. Ensure that all the seals are present and in place.
Check the harness for signs of damage or abrasion.
Check the wires at the connector. Ensure that the wires are secured tightly into the connector. Take care not to pull the wire out of the connector.
Check the exposed wires at the connectors for nicks or signs of abrasion.
Check for moisture inside the connector.
Check the connectors for dirty contacts or corroded contacts.
Check each pin and each socket of the machine harness connectors. Ensure that the contacts are properly installed. The contacts should mate correctly when the two pieces of the connector are placed together. Expected Result:The machine harness connectors are tight and free of corrosion. Results:
OK - The machine harness connectors are tight and free of corrosion. Proceed to test step 3.
NOT OK - 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 remains in the OFF position.
Disconnect the machine harness from all electronic control modules that use the Cat Data Link.
At the machine harness for the "VIMS ECM", measure the resistance between frame ground and connector contacts J1-7 (wire 893-GN(Green)) and J1-6 (wire 892-BR(Brown)) of the Cat Data Link circuit . Expected Result:The resistance is greater than 5000 ohms. Results:
OK - The resistance is greater than 5000 ohms. The harness circuit resistance is correct. Proceed to test step 4.
NOT OK - The
