Vehicle was previously tuned with SCT. They instructed me how to un marry and check that it is not married. HPT will read the FICM and Trans but not the ecm. Any Ideas ? Tried multiple times.
Thanks, Jeff

deos it read and not let you open? or just not read? because weather it is still tuned with an sct or not, it should still read it, you will just receive an error on opening, but if you cannot read at all, then you might have deeper issues
No it does not read the ECM at all. Opened a sup ticket and they stated disconnect battery and try again. Did that same thing. SCT can write it and unmarry it. But HPT reads nothing
for ECM. Only FICM and TCM
