DIC Buttons Not Working
Hi all,
My newly acquired 1998 Vette has non-working DIC buttons which makes for some difficulties, like not being able to program a new key fob and having the tire system warning pop up constantly.
I've done a bit of reading on the matter and I've tried some of the basic troubleshooting steps. I've tried pressing the buttons on the DIC numerous times to try and un-jam them (some have said that could be the issue) but no luck with that.
Would replacing the DIC module fix the issue? I see a good used condition DIC module on eBay for like $80 that I could try. Or is the issue in the cluster itself? I've heard of that being the cause too.

I would replace the DIC switch. I've replaced mine before - purchased from the same place you mentioned (fparts) . It's not hard to do - but it is time consuming.

Good to hear you've had a good experience with that! That fixed your issue? I have no problem taking apart a cluster, I've done that with both my Mustang and my BMWs.

My problem was bulbs flickering in the DIC. Replaced the bulbs and still had the same issue. Replaced the DIC switch itself with one from fparts, which was listed as used but actually looked new when I got it. I could tell that the metal contacts on the old switch were loose after I took it out. Anyway, yep - problem solved.

I don't think my cluster itself is the problem, since everything still works properly on it and I can still see the mileage along with other messages that come up, like for the active handling and cruise control.

More than likely it is an issue with the IPC itself. I have just replaced 2 IPCs for friends that had issues with the DIC buttons. I had tore the IPCs apart looking for crap on the contacts causing a short but did not find anything. Took a bit of watching the parts for sale on the forum and Craigslist to find an IPC but got them at reasonable prices.
If you have access to a Tech II use it to read the IPC error codes. This will tell you which button is bad and possibly help narrow down the issue. You can clear the code in the IPC with the Tech II after disconnecting the DIC buttons. If the code still remains as a C H then the IPC is bad.
