Your truck must already have remote key-less entry, as far as I know, for this to work. The key-less entry and TPMS are controlled through the passenger side door module. What you need is a PDM from a tahoe/yukon/escalade that already has TPMS, and the TPMS sensors. Swap the new PDM in the truck, perform the key-less remote relearn and the TPMS sensor relearn, and you are done!
Here is the factory PDM from my 2004
Here is the PDM I ordered from eBay. Notice how it says w/ TPM
TPMS sensors
This will now appear when you turn the ignition on
Scrolling through the DIC will bring you here
To perform the key-less remote relearn, follow these steps.
