Hi! Taking in my 2019 Chevy Blazer RS into chevy today to hopefully resolve the ESC (error code) message that i keep getting. i noticed it after my transmission flush last month and then it went away, now its back and quite frustrating. will update once they find the issue, my car is covered under warranty so should be nothing out of my pocket.

What did you find out? I have a 2020 that’s popping up the same and ONSTAR is sending me a SAC002 code also - and I just had my thermostat replaced
Havent dropped it off yet, but once they run diagnostic (can take 4 days) and let me know ill keep you posted. From other posts it could be a variety of things, battery, fuse, connector X2, no idea.

hey guys, SO chevy called me earlier and said that theyd need to change out my battery because its only pushing 280 V when it need to be like 850 V which COULD be causing that ESC error code on my dash. he said hes seen this before in other cars or just in general and that replacing the battery is usually the fix but cant be certain until its changes out and they continue with more tests to make sure there isnt anything else going unnoticed. However they are trying to charge me over $400 for the battery and installation = CRAZY. they are fixing my drain plug or axel plug since my transmission fluid/oil is leaking so they are going to do that first and then figure out the whole battery situation cause im not paying that price when i can buy it and have my fiance do it for $180. ill keep yall updated! id recommend to check your voltage on your battery first, if its low try changing that out first ?

hi! so my fiance changed out my battery yesterday afternoon, drove it around and boom NO ESC error code on my dash... at least for now? seems like a pretty easy and convenient fix, battery was about $170 which was great and labor was free lol.
