Re: 1996 3500HD PCM Problem
Check all the fuses to it. I saw a Chrysler with no spedometer and wouldn't shift out of first, no communication with scanner. Turned out to be just a bad fuse. Of course, you'll want to find the reason the fuse blew, if it turns out that is the problem.

Be carefull before you buy a new abs module. I had the same problem with a 97 wile I was working for GMC. The truck was a 3500hd used for Phone utility truck. The Tech2 would communicate with the ABS. I replaced all kinds of parts after GMs techline was really unable to help. A new module did not help. Checked every wire and terminal. I ended up quitting the GMC job over things like this. The reps don't always resolve the problem and the service manager is looking at you. Anyway, soapbox here.
