Tech 2 clone / AC troubleshooting

I've got an AC issue that I'm troubleshooting. According to the GM manual, the PCM has the ability to display these parameters:

AC request signal
AC compressor status
AC refrigerant pressure
AC clutch on/off status.

I'm not seeing anything in the Tech 2 clone for those parameters. Are there more options with the TIS2000 app?

Thanks in advance.

To start with, What are you working on?

Are you looking under the Engine Data Group?

It's a `99 Trans Am. I'm fairly sure I've looked everywhere.

Those older P01 red / blue connector 512k byte memory capacity PCM devices might not support the parameters that you are seeking.

That’s the PCM that I have. Would have been nice … but I have no problem pulling out my test light and dmm.
