For the SC77 with the capability to review DTCs through the dash and have the DTCs self clear after the issue is resolved, it will be very few issues that require this process. Mostly they seem to revolve around the Emissions controls equipment like O2 sensor issues or PAIR solenoid failures. Before resorting to hard clearing codes, do try resolve the underlying issue as the SC77 is very unforgiving of certain hard code errors. Disabling ABS will always result in a permanent CEL on the dash board.
thought just to share this with you guys as when im reading this thread i was very confused. because i followed grom video it didn't work. so its actually the mint and green wire. so when you look at the plug like the photo "DGR" posted its the left two slots. it will make a noise once you turn on the key so you know you are doing right. it worked for me cleared my code.
