OK - The resistance measures less than 5 ohms. The data link circuit is correct. It is unlikely that the ECM is faulty. Exit this procedure and perform this diagnostic code again. Replace the implement ECM if the cause of the diagnostic code is not found. See Testing And Adjusting, "Electronic Control Module (ECM) - Replace". STOP.
NOT OK - The resistance measures greater than 5 ohms. The machine harness is faulty. The data link circuit is open in the machine harness. Repair the machine harness or replace the machine harness. Verify that the repair eliminates the problem. STOP.
