However i dont know what either of those mean i my car decides when it wishes to hold charge at 13.7 volts being the best and 11.7 to the battery dying at the worst i replaced the battery, and i borrowed my friends alternator for a day(showed no difference between mine) Can someone please tell me what is going on with my car and what both of those codes exactly mean.
