Hi,
Unfortunately there are a number of service bulletins in relation to problems with the DIC on the Tahoe. Some of these involve problems with the transmission and no crank situations which could be resolved by replacing other components without reference to the DIC itself.
However, in the absence of other symptoms with transmission or doorlocks your problem is reflected in Bulletin 66431 which involves replacement and reprogramming of the instrument panel due to a failed DIC.
See here for more info on these DIC Service Bulletins
This company claims to fix these for $169 USD including all shipping so it would be worth looking into http://www.mrwhizard.com/
You can phone toll free to speak to them first on 1-888-803-8523
There is not much else you can do in relation to troubleshooting this issue as it requires specialist input and ultimately the DIC is highly likely to have failed. Get the dealer to check all connections and wiring first but ultimately the unit will have to be pulled and repaired.
Thanks for using FixYa.
