It even identifies as a Vibe and lists the Pontiac VIN. It seems to have full functionality with freeze frame data, live testing, etc. Sorry I have no insights to your problem, but the dealer's statement sounds bogus to me from a technical viewpoint.
I'll back you up on that! With the same setup as you, I can read my "09 Vibe with a 2.4L just fine with the Techstream software. Fine a different Toyota dealer or a shop that works on a lot of Toyota cars.
The reason I asked about the dash and A/C working is that there is a common electrical circuit to all your problems.
The airbag, power steering ECU, certification ECU, dash panel, brake actuator, steering sensor, yaw rate sensor, and A/C amplifier are all on the CAN bus communication circuit to the main body ECU. This could be a nasty one to figure out but it looks like you have lost communication on the CAN bus. Some of these systems have warning lights and some do not, like the yaw sensor. It looks like every system on the bus is down. I do not have experience with this system but if it is like other communication bus systems, it can be a pain in the you know what to find the problem. Almost any part of the system or any piece can pull the communication down so that none of the pieces can talk to the main ECU . It can get as bad as replacing each piece one by one until you find the bad part that is disrupting the communication. Of course a bad connection or broken wire in the bus circuit would do the same thing. On electrical problems like this a shop is going to charge by the hour. Finding a cheap shop may not be the best move because if they do not know what they are doing, it could cost way more then a shop that charges more but has experience with fixing CAN bus problems. They also need the proper equipment that can read all the ECU's in the car, not just the power train generic codes. A smaller dealer may be more willing to help you out than a large dealer would.

Thanks goes to MacGyver for the link.
Someone else may have a better idea if they ran into this; and it could be as simple as a broken wire but finding the problem is going to take time.
