Also if your car battery is in poor condition you will get this fault code so check your battery condition as well................. -

It comes on if the counter is over 300.000 brake sessions. So if it still is 331600 when set at 0% then it still is over that 300.000. How this can be? I don't know, better to make a log and send it to support so the techs can look into this since it seems to be a malfunction in the special option -

As I said make sure your Aux small battery is in good condition if its bit low it will trigger this fault code ..........

Have you checked the motor brushes?You have to replaced them and then you can do a reset with Maxisys. There is a function to do that. -

Hi Guys!
2day I did the test with the 4buttons resetter from china, and counter increase value like maxisys did( apologize autel team!) So, as I know , sbc generate fault if counter nerly rich 300k LEFT! My one have 301k, so dash appear this fault . Any reset increase this value by? 25, 50, 75, and 100% .Now I have 720k, so is 420k left to scrappage a car. The 2 battery are good, but after reset, nothing happend, even if I do anothing thinks like reset power after ; fault come back again!

Not sure Maxisys can reset the counter? i have seen tools that can but thats probably not a great idea. when the SBC unit fails you have NO assit.Very hard to stop. Benz had a 10 year warranty on it i believe? They did have a bulletin for replacing the ground harness at the SBC unit. When the counter has run down the correct thing to due is replace it!
