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 turn signal lamp illumination. When this bus message is received, the TIPM provides a pulsed voltage output through the rear turn signal control circuit. The rear turn signal control circuit connects to the dual filament Park and Turn Signal Bulb in the Lamp, Tail Stop Turn. The same ground circuit is used for both the Park and Turn Signal filaments in a dual filament lamp. For additional information on the Turn Signal Lamps operation. Refer to Operation .
