Only the Chrysler dealers system can read the alarm trigger codes (I have yet to see a scanner system gain access to that section of the system).

I chased an alarm problem for months with random triggers and while many here on the forum were calling for replacing alarm sirens, it turned out to be the switch in the glove box that was tripping the system when it got too hot or too cold.
