I had the vxdiag vcx nano for GM with GDS2 software. It can do sorts of fun things with the vcx nano software package. Once you get gds2 running, you can reset all these modules.
You can get software download on ACDelco TDS and you can get new module software for 40 bucks for two years for any car you own. That’s pretty slick deal.
I use my VCX Nano to reset the lifetime mpg on my new (to me) 2012 Chevy Volt today.
This kind of bugged me 54.8 miles per gallon, I had to feature out a way to reset that. Here I have my windows 10 laptop, it is kind of a pain to run vxdiag gm gds2 but finally got set up.
If you want to reset lifetime MPG, go to Module diagnostic – Hybrid powertrain control module 2 – Configuration/reset functions – Reset functions – Fuel economy reset
Get the bars here, hit the Reset button
We got 250mpgs it can be done
