Default Scan tool to deep dive to bcm

Good evening! Have an '04 Z06. I'm interested in knowing what scan tool might be out there that mimics the GM-TECH2. If so, are they real expensive or reasonable.. What I'm wanting to do is turn on the TPMS system (I've already bought and installed the correct Shrader 20117 sensors). .My understanding is I need to access this feature in the Body Control Module. Interested while I'm there to also turn on the twilight lighting function. I see the TECH2 scanners going for over $400. Would a tool that enables these features also allow access to the fan settings to come on sooner then the factory setup? Any of you done these with other than the GM-TECH2 scan tool? Or, should I just bite the bullet and pay a dealer to do this $$$? Pic of her after I did the fog light addition.


Appreciate your response.

Thanks Sam for this recommendation. Have you personally used this with success to access where I’m trying to go?

Again, if this works, much appreciated!

Regards,

Jim

I bought a tech 2 "clone." Other than it taking forever to arrive, it was reasonably priced and works as expected.

The reason I put clone in quotes is because it seems to be the real thing without any of the stickers put on. The stickers were included, though.

There are numerous ways to tell the fakes from the originals, but the fake Tech2 seem to work for most.

It is inexpensive but you need a laptop to use it with the provided software. The software works well once you get it installed correctly. They have probably updated the install software since I installed mine a few years ago. There used to be problems with windows 10 and USB driver's.
