Theory of Operation
WARNING: This page is about a different car, the 2011 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The Totally Integrated Power Module (TIPM) receives a bus message requesting park lamp illumination. When this bus message is received, the TIPM provides a voltage output through the park lamp circuits. Two of the park lamp circuits are controlled by the TIPM through a relay. The other circuit is controlled directly by the TIPM. For additional information on the operation of the Park Lamps. Refer to Operation .
