Doesn't the manual somewhere list the MIL codes? I would think it should... what's the point in having user-accessible diagnostics if they don't let you know what they are?
Computer controll engine, is not an end all for trouble shooting. You will not get a "light' for a verity of possible malfunctions IE bad TCI, fuel pump not pumping, oil leaks, loose wires.You still need to go back to basics, then check codes. Oh this works for cars too.
