2015 Tahoe LTZ with push to start. Not sure if I noticed it before but read out with latest version of V8. Saved. Turned of AFM and deactivation solenoids only. Licensed and reflashed. Obviously the normal push button routine of fob in vehicle. One press on without hitting brake for key on. Flash finished without issue. Now radio is flickering on and off randomly. Coincidence or something within the flash? I know efi doesn
Never had any issues with identical vehicles before.
Do you have anything else (i.e. aftermarket) on the CAN bus...?
Check radio's ground connection.
Does radio flickering occur when anything is plugged into to ALDL/OBD2 port...? Or only when nothing is plugged in...?
I am thinking electrical. No issues any time other than after the initial flash however I am thinking coincidence at this point on timing. Vehicle and radio are 100% stock.Quote:
