There has to be communication or I would expect a "U" code to show in the computer. If they have found that communication occurs up to the "disk" but no further, then that would be the next logical step.

Does it not speak to you or does it not listen to you?

I don't have any helpful info on this other than advice.

Ask the service manager that if it doesn't fix it, what kind of hit are they willing to take on it. They should not profit from a bad guess. There are situations that come down to an educated guess, but the wrong solution should not be rewarded with profit IMHO.
