The module that controls the TPM on your truck is the remote control door lock receiver (RCDLR). For me to change the settings I'd have to have to truck. It's about 5 hours one way drive for 2 minutes worth of work. The RCDLR will usually turn on the message to check the tire pressures when it detects one of the tires is 7 PSI above or below the setting. Check the door jamb sticker for the factory tire settings.
