Check engine codes
I have a 1993 SHO 3.2 automatic. I checked the check engine codes today since I found out how. They were all read with switch on and engine off. Here they are: 522 (Hard Fault), 181, 189, 634, 647 (Memory). I know what they mean but don't know what to do to fix them. Can anyone help...- larben
