Sorry for the stupid question, but is it possible to read codes without the JB4's USB cable? Meaning, can they be seen on the dash or anything? The cable is dirt cheap but I loathe taking the cowl apart to access the ECU compartment. I can never get that damn thing lined up on there properly when I'm trying to reinstall it.
I do have the OBD2 cable for coding. Anything I can do with that?
