New Pressure Sensor(s) Needed????
When I started the car yesterday, the "Service Tire Monitor" message appeared on the DIC and the RR sensor shows "XX PSI", so I think I have a dead sensor in that tire or could it be something in the BCM?
If it's the senor, I am inclined to replace all four sensors to have the best situation of not having a second or third sensor die and I have to go through this all over again.
Can my dealer verify whether it's just the sensor or something else?

The tool they use can check the sensors while they are in the wheel on the car, a good tire shop would also have this tool.
If you lived nearby I would check them for you, but your just a little too far out of the way for me

Have you disconnected the battery, or has it run down?
Did you drive the car, or were you just starting it up while it's in winter storage?
If the battery is disconnected or runs down the TPMS will lose the last known pressures. In that case you must drive the car faster than about 20 mph for a few minutes to wake up the sensors and get them transmitting in the drive mode (transmitting once per minute). That should get the DIC displaying the proper pressures again.
If that doesn't work, you've either got a bad sensor, or maybe they just need to be programmed again.

I don't think it's the "Tire Monitor" (TPMS) at all. The TPMS is actually a part of the RCDLR (Remote Control Door Lock Receiver) module. I can't recall ever hearing of the TPMS failing. You get that message for many tire pressure sensor problems.

No, the battery is fine and it hasn't been disconnected.

I don't really store the car for the winter; just keep it in the garage ready to go for when we get a clear 50+ degree day. I had driven it last week and did not get the message and it had sat for two weeks without being started prior to that.

We drove 300+ miles with several shutoffs and restarts before getting home.

Update...
When I took the car for a drive tonight after work after I let the car sit overnight outside...
, the "Service Tire Monitor" message did not appear and the RR tire sensor was reading the correct pressure.
I stopped somewhere for an hour and when I restarted the car to drive home everything was normal and all of the sensors were operating correctly.
I appreciate all of the comments, recommendations and replies and will keep this in my list of subscribed threads for future reference.
Thanks again to all...Happy motoring....

The battery in the sensor could be going bad. Depending on when your car was built it could be close to 6 years old. 6 years is about the average life time on a tire pressure sensor in the C5s so probably not any different with a C6. The fact the system showed the pressures at the other sensors indicates it is not a problem with the part of the system mounted in the car body. If it works for one then it will work for all so the problem is in the sensor.
