i recently went to repair my AC, diagnostics showed high voltage at the AC pressure transducer, replaced transducer and found wiring shorted out on frame, repaired wiring and still have high voltage reading that seems to be in the tipm itself. Detuned ecm to factory, while waiting on answer for tipm repair, then decided to retune back to superchip for towing. During the retuning it seems I lost communication, code reader will not work says problems in communication, engine check light started flashing rapidly. Have checked fuses, have full 12.5vdc, have visually inspected wiring to tipm and ecm and do not see any damage. No blue smoke has escaped from any of the wiring that I can see, what have I missed or need to check next. Any and all help, suggestions, criticisms welcome as automotive computers are new to me and I'm being forced to learn. Thanks in advance.
