Not sure if it makes a difference, was just curious. After random REP issue with my Tahoe for 2 years while driving, I happened to pinpoint the issue to the 16pin connector on the Tac module. Replaced that connector and issue went away for 2 years. Then all the sudden started getting REP on startup like you are about twice a week sometimes more when it was hot outside. Never again got it while driving. Chased the issue for about 2 years cleaning grounds, adding grounds, etc. Never fixed it. Was the main reason I sold it so cheap, because couldn’t in my right mind pawn that off on someone. Fortunately new owner just wanted a truck to play around with and said he was ok with trying to figure it out.
