It'* unlikely that anything your dad did with the scan tool caused this (unless he did a relearn with the car on the hoist). There are however several things that may be a problem. If you can access a scan tool, you should check the function of the ALC exhaust valve to make sure it'* working. Also, as I mentioned before, you can try an ALC relearn. If these don't solve the problem and you end up replacing the sensor, you will need to perform the ALC relearn anyway.
If you're not in a hurry, I'm bringing my Tech 2 with me when I head down that way.
