Code 10 is the brake test did not pass during selftest, tests to run are A35 brake test and O00 toggle TPC. Check wiring to electric brake, I found a bad connection at the relay card last time, the funny thing is I have the same unit in the shop with the same code again now and its not the relay card this time. Still looking for an answer. Let me know if you come up with anything on your end.

I am getting this code at selftest also and it is not in my manual, have you fixed this problem yet?
