I have a Dodge/Ram/Chrysler/Jeep programmer and can program many functions on your vehicle such as:
Auto Start
Auto Window down
LED lighting (that throws bulb out message)
Trailer Tow brakes
Tow mirror blinkers/puddle lights
Can also turn off TPMS if you have aftermarket wheels withou sensors and are tired of looking at that yellow TPMS icon.
These functions are all embedded in your vehicles computer but require a programmer to toggle them on or off.
