PCM locked, PCM in unknown state, seed not accepted ?
PCM locked, PCM in unknown state, seed not accepted ? I get this message when I try to read the calibraton file from an '01 Corvette, it won't read or write to the PCM, what gives ?
GM just did a recall flash on it for the column lock, they don't lock PCM's now do they ?
