Autoenginuity not talking to A/C

Does anyone here have an Autoenginuty with the Toyota expansion?

Mine won't talk to the A/C system. When I select the A/C system, it comes back with "no response from module." Everything else seems to work.

The guys at AE basically told me that it should work, and would most likely work if I tried the scan tool on a different Prius. They mentioned something about the A/C system being from a 3rd party supplier.

Anybody encounter this issue?
