Hello it appears you have a issue with the stop light switch. I would have that replaced and erase the codes and see if the problem is taken care of. Hope this information helps.

Hi and Welcome to Just Answer!

Check battery charge as well and alternator performance. Low system voltage can cause this problems.

Hi, This code C1611 will set when SBC unit and ESP unit are not compatible. Somehow the unit you have installed is not I match for the vehicle ESP software. As for shifter not working it may be separate issue. common problem is sticky residue in shifter accumulated over the years from coffee spills, removing shifter and cleaning it helps in most cases,

If you have the old SBC unit you can try to swap EEPROM or if you have an access to a Arbitus tool you can copy file from old unit and download it to new unit. Or as you have paid already a top dollar for the reman unit from Dealer, just take it back and let them deal with it.
