I have 1998 dodge ram 3/4 ton with the 24 valve cummins with 292,301 miles and my guage cluster doesnt work. It lights up and I have my tach and thats it. No other guages work. Ive been chasing wires with wiring diagrams so find broken wires and I havent found any. Im thinking the ECM (the one on the driver side of the block might be the culprit but im not positive and dont want to spend a bunch more money without finding out for sure

Do you
have the same problem?

I would verify power to the cluster. If you have it, then the cluster is most likely the failure, not the pcm

I did verify the cluster works. I did the "cluster check" and I put it in my buddys truck that has the same exact truck. The reason im thinking ECM is because thats about the only thing I havent been able to test or check

Yes. The only code I get is a "bus error" or something along those lines.

Not a code reader, an actual scan tool
