Instrument cluster issues

Recommended Posts

Hey there,

I have a 2000 Cummins that I've been building for about 7months.  I put a new cab on it and dash.  The dash is a 98.  I've got everything hooked up but when I turn the key to start it, I'm not getting any dummy lights, check engine lights, or even an odometer.  The backlights work and all the guages seem to twitch/reset.  


Anyone have any info on what could cause this? Dead/low batteries? Grounds? 


Thanks guys.

Clash of software. The cluster has to be a match for the PCM to make the CCD network being the PCM is the source of the CCD network and the cluster gives Bus Bias to the network so if there is a software mismatch then most likely it will not work. Really common with franken-trucks that get assembled from mismatched parts. 


Solution: get matching ECM, PCM and Cluster from the same truck and same year.
