Thread: how to remove "Service Tire Monitor System"

This part changed in 07 because it has to be capable to receieve signals from the pressure sensors, The connectors are different just enough that they wont plug in so you will have to splice a connector or make an adapter harness and make a slight wiring modification so the keyless entry reciever has a direct link to the serial bus of the car.

The keyless entry reciever sends the tire pressure data over the serial bus where the dic picks it up and displays it.
The keyless entry reciever will have to me reprogramed for your new remotes, as well as learning the tire sensors.

Clearly he's already got it installed, and I doubt he needed to do any of that. Also, the DIC receives its data through a Class II data line so everything is serialized, meaning there really aren't that many individual signals going into it. If you need more information to go to the DIC (e.g. TPMS sensors) you just serialize it into the data stream and then update the software on the DIC.

Edit: Somehow I misread a lot of your post lol so most of my garbage can be disregarded. My bad :P
