I bought this project truck, an 04 1500 Hemi. It turns out the yokels i bought it from were scum. They took apart the gauge cluster and removed the check engine bulb. Tried to put an led on it and it went nuts when i fired it up. Anyway, i put another cluster in it and the check engine light is on and it throws a code that apparently does not exist? The code is uo 155. This is a new one on me!!!!

 

Thats a body code. Lost communication with instrument cluster. That should be a fun one to fix.....

Welcome to DF, post in the third gen ram section, someone there should be able to help you out.
