VSC lights on, 4WD and DAC not working HELP!

[Bivens-L1C4]

I have a 2004 Sport Package. The VSC lights have come on and neither the 4wd or DAC will engage. When I push either button they will not work, lights just flash. Other than taking it to the dealer, anyone got any other suggestions? Thanks.

Find an ABS capable scan tool and get the DTCs stored in the Skid Control ECU and possibly the 4WD module (unsure if an ABS capable non-factory tool will communicate with this module...)

Also, DAC will only work in 4lo, so if you can't get to that mode it will only blink.
