Dreaded No Bus.

[DoubleaughtDodge]

Hey guys. New to the thread. 2000 Ram 1500, 5.2 magnum, and I got the dreaded no bus. Truck runs and drives ok, no gauges. Replaced the ECM as it fixed my old truck but didn't fix this one. I Ran the gauge diagnostics and everything checked out there. Also no DTC's when scanned.

Whats next to look for. Thanks!

I would post this in 2nd gen section, not 3rd gen section.

If the truck still runs with the NOBUS message in the odometer, then the PCM is most likely not the problem. I would start by checking the wiring and plugs for the cluster all the way back to the PCM and CTM.
