As long as it is the same dongle connection the AP will read the code from other cars.
He needs to reset the ECU to see if the code will go away. I get a little code sometimes if I get a drop of water on the air filter. I use the AP to reset the ecu, there is a feature in there that wipes the codes.
He can disconnect the ground battery cable. Leave it disconnected for several minutes. This will clear the code. When you start the car back up it should be gone, it may or may not come back depending on if the issue is still there.
I may be there Friday, if not I do not live far from there.
