Since I got my truck, the gauges haven't worked. The abs, fuel,airbag lights stay on all the time. I checked and cleaned all grounds and codes. I'm getting 2 cluster codes. No speed pulse from ecm and no distance pulse from ecm. My scanner shows that I'm getting a speedo pulse from the ecm to the diagnostic port but I guess the cluster wiring could have a break somewhere between the ecm and the cluster. The cluster has been changed already but that doesn't mean this hasn't happened before and the repacement cluster burned out again.

 

sounds like a ecm problem. try finding a buddy with a truck like yours same motor trans etc and try there ecm on yours but i wouldnt put your ecm on there truck

 

I thought that at first because the other scanner showed that I was not getting a speedo signal but the matco scanner does.
