TPM reprogram issue -- Parking brake?

[Tones H3]

Ok....I am baffled. I am trying to reprogram my TPM system. I have been getting the SERV TPM warning coming on continually on the DIC. This issue started after doing a tire switchover on the stock rims. The problem is I cannot activate the repogram procedure. I have followed the instructions in the manual, but I cannot get the reprogram to start. (The manual says I should hear to horn beeps and confirmation the the DIC.) After going nuts for an hour, I finally called my dealer. He said to make sure the vehicle has the parking brake engaged or the reprogram will not work. (which i did). I went back out and tried again and this time i noticed that when i engage the parking brake i am not getting any confirmation of this on the DIC. Shouldn't it say "Parking Brake" on the display? Yes i have checked to make sure the parking brake is all the way down. Could this be not letting me activate the repogram functions? Anyone have any ideas on how to resolve this??


Thanks
