Could This Be a BCM Issue?

I changed the Steering Position Sensor right? I know I bumped the BCM. Now I can't get any TPMS readings, nor does the manual learn work. I get the two horn beeps acknowledging it's ready but I get nothing when letting air out of the DS front tire. Is this BCM controlled?

I believe that it is BCM controlled, but I'll let more knowledgeable folks here chime to confirm or deny.

So taking someone's advice I took it to America's Tires and the tech there couldn't get any of the was wheels to read. The vehicle enters the learn mode but nothing responds. I'm at a loss.

I believe the signal comes in through the RCDLR or remote door lock receiver if that helps. I thought it was the passenger lock switch but not certain.
Just some info

George B I responded on the other thread I couldn't find this but now I have. I don't know if this applies to my '05. And both remotes have fresh batteries and work great. So, no connection maybe?

So just now seeing this... If I read the thread right you have an 05? I have an 05 Yukon. On mine the TPMS is part of the passenger door module. Last time I tried the relearn it failed over and over on the last wheel. In my case I was fortunate to have the sensor ID numbers and I was able to use an OBD2 adapter and write the values to the correct location myself.

have you tried any other wheels? maybe that one tpms sensor has a low or dead battery, if the others work that would confirm or rotate the wheels to confirm if others work
