This is a tsb for an intermittent idle rpm drop. Meaning it doesn't necessarily have to happen for a tech. This will get you flashed to b01c which not only fixes the cause of the DI failure but has some other perks on top of the a01c calibration. I had this done and am quite pleased. This will not repair any damage you may have already suffered, but it should ensure it doesn't happen again once fixed. Went from 700c to b01c.
