There probably isn't a C5/Z06 question that hasn't been asked and answered a thousand times on this site. The best way I've found to get technical questions answered is with research in C5 Tech forum.
Go to the C5 tech forum and click on "search this forum" (in the red banner) and use keywords to describe what you're looking for.
For example, "pulling codes from DIC" in this case. You'll find numerous pages of past discussions that will undoubtedly help you.
You might also look at your owners manual. Rudimentary as it is, it does have a wealth of information. If you don't have one, you can still buy them from a number of sources, including EBAY. Or, you can download your manual from site supporting vendor GMPARTSHOUSE...click on "downloads". They're in a PDF format.

You can also check the sticky topics on the top of the C5 Tech and C5 General forums for great information that applies to anything C5/Z06.
Here is another site that provides information on codes pulled from the DIC.

If the two sites provided don't point you in the right direction, post back in C5 Tech. Someone will help you...

I am sending you an e-mail with a PDF file detailing the diagnostics for those two codes. A code only tells you a symptom of a problem has been detected. It doesn't necessarily tell you what the problem part is. Both of your codes could be caused by poor voltage levels. Start with checking the battery condition and the wiring to the battery. Unlike later model C5s the EBTCM on your 97 is located in the rear by the diff. Check all of the wiring and grounds associated with it and make sure the contacts are making contact and are clean and free of corrosion. P1571 indicates the PCM isn't receiving the required torque signal. This could be due to poor contacts/grounds causing a low voltage signal, a problem with the battery, a problem with the EBTCM/PCM wiring, a problem with the EBTCM, or a problem with the PCM. P1626 isn't related to the TC problem but could result in a starting issue if not addressed. Your PCM is in failed enable mode as communication between the PCM and BCM have been lost. This could also be another indication that you need to check the battery condition and the connections at both battery posts for corrosion/loose grounds, etc.
