0 Mack Technician Posted October 23, 2017 Share Posted October 23, 2017 (edited) J1939 is a general term for a "CAN"- Controller Area Network. It's full name is SAE J1939 (society of engineers). AKA- Lots of computer inputs going down one shared line. Can think of it as "common access network". It is dedicated to communications and diagnostics. Usually a three twisted-wire (yellow+green + black) harness that you can identify by it's triangular connection. Yours is having a communication issue. What is the blink code number?
