I have 94 f150. I did my own diagnostic and came up with a code of 539. I have been looking on the e-net for hours for a list of codes and can't find any codes before 1997. The code I come up with has no letters. What the hell. Please help.

I have a list of OBD-1 codes which list # 539 "Air Conditioning on during self-test." There is no listing for a 539 code for OBD-II systems.
