Brake, ABS, VSC and ! lights on after smog inspection

Yesterday, I got a smog inspection on my 2008 Prius which has 100K miles on it. The smog inspection passed.
But after driving away from the shop, I noticed my handbrake light on. I checked it and it was disengaged. Then I noticed that the !, ABS, and VSC lights were all on.

I took it back to the shop and discussed it with the technician. He said all he did was hook it up to the port under the dash (OBD, I think).

I checked these forums and did a bit of trouble shooting. I plan to take it to another shop tomorrow if I can't figure it out.

I used the jumper method and wrote down the codes:
! - 66, 95
ABS - 42
VSC - 45

I tried pumping the brake 8 times to clear the codes but this did not work for me. I tried several times.

This morning after the car had been unused overnight, I checked the 12V battery. It read 14V, so the battery
seems to be good. I think it is 6 years old.

I have a number of questions:
1. Is there any possibility that the technician caused the issue simply by connecting up to the OBD or did
this just trigger something to cause the lights to go on?
2. Does anyone know what the codes might indicate? Could it be a sensor malfunction or could it be
that something simply needs to be reset?

Any help is appreciated!

Thanks,
Geoff

 

The 14V reading was with the car off (IGN-OFF).

I tried disconnecting the battery and left it disconnected for 20 minutes.

The codes were still there.

 

Just wanted to follow up on this in case anyone is interested in how it turned out.

I called my regular mechanic on Monday morning. I had gone to another mechanic to get the smog check
because my mechanic doesn't do smog checks.

I described the issue and he asked if my car had been on a dynanometer (treadmill). I told him I think
it was because I saw one at the smog shop. He thought that probably what happened is that the
computer got really confused because the back wheels were turning and the front wheels weren't.
He suggested that I just drive the car for a couple of days and the lights should go off. And if they
don't, then take the card in to him and he would reset the codes.

So the lights did not go off after 2 days of driving, so I took it in to him. He hooked it up to his
diagnostic tools and told me later that he wasn't sure what they had done, but the computer
was totally screwed up. Simply resetting the codes didn't work. He had to do some additional
re-calibration of the ABS system. Now the lights are off.

Needless to say, the next time I have to get a smog check I'll go somewhere else...

 

Exactly, there was no need to put it on a treadmill. I'm not really sure what they did, but somehow the computer was totally screwed up.
I did try the pin8/13 trick and did try pumping the brakes 8x in 5 seconds, but the lights would always come back. I tried this several times.
I'm not sure exactly what my mechanic did, but he did mention that things were totally screwed up. Since he was willing to do it for me, I didn't really spend too much more time trying to figure it out.

audiodave, regarding the numbers, the certificate I got just listed a bunch of tests with "passed" next to them. When I had an older car, a 1995 model year, I remember I would always get numbers. Probably that's because they had to actually measure things. With newer cars, the car already has all the numbers, from what I understand.

By the way I found the following link describing smog testing in California. I found it very informative:
