How big is the J1939 data link connector?
What I see all the time are inactive codes in the ABS for J1939 time outs on Freightliner Columbia. The trucks that were checked had measurements that were about 65 to 68 ohms on pins C and D of the 9 pin data link connector. In most data link troubleshooting text books this is an acceptable measurement and falls within the 60 ohms + or – 10 ohms.
What to do if no communication through OBD connector?

If it comes down to this, post a reply to this solution and let me know.
