Hey guys, I'm new to this forum stuff but i think I've read every post about the NoBus issue. Not sure if I can jump in here, but if you can help me, please do. My cherokee is a 2001. I got the nobus intermittently at first but it seems to be on for good now. I've removed the instrument cluster and put the dielectric grease on. Checked CPS and it seems good. By the way, I forgot to mention that the jeep runs great, just got no guages on cluster. My mechanic checked the codes and says it all points to the PCM. Seems like I've seen a lot of these changed with no results. Is there a way to test the PCM before buying one? Any help appreciated.
