I hear what you are saying, but by law all vehicles starting in the year 1996 were required to have OBD2. The question then becomes, were other systems such as ABS included in the OBD2 standard. From what I can gather, the OBD2 standard was primarily concerned with emissions and other systems were not specifically called out. The manufacturer may include other systems as an enhanced feature of their OBD2 functionality. Obviously, there are two different sets of fault codes. OBD2 and Dealer specific.
The ABS system fault codes still have to be read, so even at the dealership the options could only be that the ABS codes are dealer specific codes that can only be read with their software or that the dealership had to insert a jumper wire to decode the faults. Since I do not know any Honda dealership mechanics I can't verify which is true. If I were to assume that they are dealer specific codes that can be read with an OBD2 scanner with the proper software, that leads me back to my original question, can my Autel scanner read those codes?
I have in the past read fault codes on my Honda using the jumper method. The Autel scanner is a new purchase for me and it has it's limitations and like all electronics it has it's bugs. I was just curious if one of those limitations or bugs were related to my vehicle. I am awaiting a reply from tech support regarding this very issue.
