There are 2 different tire pressure monitoring systems. The base system can read tire pressure but does not know where the tire is on the car. The premium system knows where the tire is on the car. What you need to get the individual tire pressure readings in the EVIC is the premium tire pressure monitor system and what you have is the base system.
As for DevSlash, there are also more than one level of EVIC and he does not have the level that allows him to select customer programmable features.

You are correct, but with the Chrysler Town & Country, their EVIC is the premium system, you figured that with the top of the line Dodge, they SHOULD use the same system. We know the tire sensors are the same, it is the EVIC part that needs to be modify, and with today's electronic you would think it is just a software upgrade to turn on & off these functions.

The EVIC just reads the information off the bus. If there isn't information to read, it cant. It's a module that is needed to give the EVIC the information that it needs. My wife say's they should only offer loaded vehicles, if you don't want the option, don't use it. Less confusion on what your getting and what your not.
Here is the system description from the service manual and the difference between the two.
The Tire Pressure Monitoring (TPM) system monitors air pressure in the four road tires (excludes spare). Pressure in the spare tire is not monitored.
There are two tire pressure monitoring systems available, a base system and a premium system. The base system does not specify how many tires are low or where they are located. The premium system does so.
The Base TPM system consists of tire pressure monitoring sensors attached to each road wheel through the valve stem mounting hole, a central receiver module (Wireless Ignition Node (WIN)), and an indicator lamp.
The receiver circuit for the TPM system is integrated into the WIN. For non-remote start vehicles, the antenna is internal to the WIN. For factory installed remote start vehicles, the antenna is external to the WIN. The WIN can also include the Remote Keyless Entry (RKE) receiver, Remote Start (if equipped) and the Sentry Key Immobilizer (SKIM) receiver. All receivers share a number of common components. The WIN decodes the RF signals transmitted by each of the vehicle’s tire pressure sensors. The decoded information is used to determine if "warning" or "fault" conditions exist within the TPM system.
Upon detection of a warning or fault condition, the WIN will send a request to the module that controls the indicator lamp (and the text display if equipped with the Premium system) via the vehicle bus system to illuminate or flash the indicator lamp. Also, upon detection of a warning or fault condition, the electronic display will send a request to sound the "chime".
The WIN will store all warning and fault conditions, placard pressure values and low-pressure threshold values (lamp ON and OFF) in memory that can be accessed through diagnostic communication. If new sensors are introduced to the vehicle, the data stored for the sensor being replaced will be deleted.
The WIN will store all wheel sensor ID’s and locations and faults in memory that can be accessed through diagnostic communication. All other data values transmitted from each active wheel sensor (not the spare tire) shall be stored in the WIN memory.
The WIN automatically learns and stores the sensor IDs while driving “within 20 minutes continuously above 15 mph (24 km/h)” after a sensor has been replaced. The learning sequence will initiate when the vehicle has been stopped for more than 20 minutes.
The Premium TPM system consists of tire pressure monitoring sensors attached to each road wheel through the valve stem mounting hole and a TPM module. The receiver circuit for the TPM system is mounted in the left rear wheel well. The TPM module is fixed to a metal bracket mounted to the inner wheel well located behind the splash shield. The TPM module decodes the RF signals transmitted by each of the vehicle’s tire pressure sensors. The decoded information is used to determine if "warning" or "fault" conditions exist within the TPM system.

The TPM module will store all warning and fault conditions, placard pressure values and low pressure threshold values (lamp ON and OFF) in memory that can be accessed through diagnostic communication. If new sensors are introduced to the vehicle, the data stored for the sensor being replaced will be deleted once the new sensor id has been learned.

The TPM module automatically learns and stores the sensor IDs while driving “within 20 minutes continuously above 15 mph (24 km/h)” after a sensor has been replaced. The learning sequence will initiate when the vehicle has been stopped for more than 20 minutes.
NOTE: A new sensor ID can also be programmed directly into the WIN or TPM module by using a RKE-TPM Analyzer in conjunction with a Scan Tool. Once the new sensor ID has been programmed, the vehicle will need to be driven above 15mph until the fault is no longer active (lamp extinguishes) and display is updated (for up to 20 minutes).
NOTE: Using a TPM-RKE Analyzer can take up to a minute to force a transmission from a sensor.
