People have screen names for past cars so I don't assume...why because I end up searching the wrong information. Logging into the service information website and searching the wrong data is a waste of my time...so I ask for clarification. I asked multiple times.
I would think someone with 2 degrees in communication would ask why the information was needed. YOUR smart *** reply to this request; your education has failed you.

 

Can someone else possibly help me with this?

 

As far as your remote start function, is it on a factory key fob or aftermarket. If it's aftermarket, it may not have been fully compatible. If a GM fob, try replacing it's battery.

 

The remote start won't work because I have an engine code (oxygen sensor). That isn't the issue. The issue is, all four TPMS sensors aren't working. Logically, it must be the module. I'm just trying to find out, is the module the white module under the dash? If it isn't, then where is the module?

 

Was there any work performed such as tire rotation, brake service, new tires installed that could have prompted this. Not sure if you advised this in your original post.
