So in the front we changed the spark plugs, cleaned the MAF, change the engine air filter, serpentine belt and idler pulley. In the rear, cleaned the battery cooling fan (really nasty) and changed both rear tail lights. For safely, I did remove the main battery plug (orange jumper on the driver's side of the battery. All back together but no codes and no start, just all the warning lights. Next is an oil change but cannot get it up on ramps if no power... Is there something I should reset? SM-G973U ?
Got it... when I closed the HV plug, i forgot to press it down... (feeling like a moron...) SM-G973U ?
There was no need to remove the traction battery interlock if you were not messing with the high voltage orange cables, BTW. It’s good that you figured out how to correctly reinstall it. If you are concerned about safety, disconnect the 12V battery which will totally disable all electrical circuits. Then you don’t have to worry about the engine starting while you are removing the serpentine belt.
