Theory Of Operation

WARNING: This page is about a different car, the 2012 RAM Pickup and 2012 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The Totally Integrated Power Module (TIPM) monitors the hardwired ignition switch output circuit from the ignition switch or Wireless Ignition Node (WIN) and compares it to the ignition switch status message received over the Controller Area Network (CAN) bus.
