Try reading in low speed mode.
It doesn't have to be perfect, it just needs to be done in two weeks...

during the vcm .... im walking away from it as its reading but its on 6% this time so far so good ... I hooked up the charger this time
still going at 28%
likely just a comms issue, if it doesn't read you'll likely need to read it on a bench harness.

thank you bill this time it took!!! battery charger and slow mode !
that battery charger can kill your interface. it did one of mine.
One issue I had with a vette not too long ago, I had to actually wire tie the mpvi plug to the cars odbc connector. For some reason I had a number of read problems. Once I did that and it seemed to make good contact reads and writes were no problem.
