San Antonio shop with a GM Tech II Scanner?

[TXAgZ28]

Looking for a shop in San Antonio that has a GM Tech II available that can adjust the range of the TMPS sensors on my truck. I had a buddy at the dealership do it a while back, but he's not there anymore.

Anyone?

Darn it, that's one tool I've been meaning to acquire, maybe someday.

Yup, Nelson was the first place I thought of before I had it done the first time.

Argh!

Use a DVOM instead. It's a three wire deal so all you need to do is put the positive lead of the meter on the signal wire and the negative lead of the meter on chassis ground. You'll read the same signal voltage as the TechII as long as the 5V and low reference circuits are OK.

I'm not quite following you. How does a DVOM adjust the upper and lower limits of my TPMS?

Sorry, read it as TPS. TechII can change the load range and pressure from about 24 to about 65. Sorry.
