TPMS Message on the DIC 2003 Roadster
On my 2003 50th Anniversary roadster I got the "Serv.Tire Mon. Sys." on the DIC.
I also get a psi reading on the front left and right and the rear left when I cycle through but get a right rear of xxx. When I got the message the first time, I pulled over and checked the tire pressure and it was spot on.
I pulled the codes and under BO-RFA I get C2115 H C so I am guessing that that is the code I need to address. Any suggestions on what I need to do to fix this problem?
I am thinking of replacing the tires - they are 8 years old but with good tread but not run flats so if I do need to replace the tire pressure monitoring unit (or units) this is probably a good time to do so.

I agree. Replace them all.
C2115 is for the LEFT rear TPMS and not the right rear. However if the two rear tires were switched and the TPMS not relearned you would have the condition you report.
The battery life in the TPMS is around 8 to 10 years. Some last less and some more. If your TPMS are the original they are at their lifes end or near so. If you plan to replace tires that would be a good time to replace all 4 TPMS. You can program the new TPMS while sitting in the drivers seat with the TPMS where you can reach them. Just mark them for which tire they are to go into and insure that the tire changer follows that order. Here is a video of how to train the TPMS:

They will all fail soon. Do a search. You can buy Schrader TPMsensors for $40.00 or less each delivered online. I just used a Tech II to disable the TPMS on my 02. I was getting service message and did not want to break down my new Continentals and chrome wheel sets to replace them. When and if I ever need new tires I will replace and train new sensors after I enable the system with the Tech II. If I had run flats, I would have replaced all 4 then and now.

Thanks. I wondered about that once I was able to find the code online. I bought the car used and it does not have the original tires so it appears that the monitors may have been switched when the tires were replaced. Now I just have to identify some appropriate tires!

Yep,
You might want to stay with the Schrader original equipment brand. There are several other brands out there but the method for making them sync up to the car differ and can often be problematic. Some require letting air out of the tires to get them to transmit for programming, and others require special programming tools to get them to transmit. 
Here is a link to Delco OEM sensors for $25 each which is not a bad price:

Go with Schrader or Delco OEM and readily available year/ model specific.

PS Based upon your readouts, you likely have all the orginals which are now failing as expected.
