DIC not working properly, a few other things

[AspenSTi]

I signed up for this forum so I could search it, but for some reason when I write "DIC" in the keyword, it comes up with zero results, even though I see a thread title with "DIC" in it on the very first page here.

The DIC in a 98 Grand Prix GT I'm helping to sell is flashing zeroes in every category. This happened directly after the ignition switch was replaced. I keep finding references online that they are related but haven't found out how yet, or how I could fix it.

The ABS light went on as well as the traction control off light. I checked for codes from the obd, none were displayed, but I didn't know if those would store or code there or not.

Also at the same time the radio display went out. It still works on the HUD, but I saw someone mention that searching online that they might be related.

Unrelated, the SRS Airbag light has been on in this car for 10 years. It's been checked out more than once and was found the airbag system was fine. Is this a common thing?

Thanks for your help

In order to display abs brake and transmission DTC codes you will need a code scanner that is capable to read the DTC codes for trans and brakes. The GM tech2 will be capable or contact a trans shop they usually have the scanners that will read the trans codes and the abs brake codes.
