Receiving “abs module “ code in mileage box area. After reading HeavyD’s previous posts, I pulled harness from radar and DIU to test. DIU had 0 voltage on J1939 to ground. Radar side of harness voltage was 0.3 for power supply and no voltage reading j1939 high side. Did some research and it’s recommended to replace entire harness. HeavyD, can old harness stay on truck (disconnected) and run the new harness along side of it? Also is there a wiring diagram for this harness available?

Yes, just run new wires. Complete replacement harnesses are not easy to get and not easy to get the right ones either. Most radars only have 4 wires. Pink is 12 volts, white is ground, and yellow and green are your datalinks.

If the new harness is missing the wires I would first see if they got you the right one. If so, then you will have to run new wires.
