Theory Of Operation

WARNING: This page is about a different car, the 2016 Jeep Wrangler and 2015 Jeep Wrangler. 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 front turn signal control circuit. The front turn signal control circuit connects to the dual filament Park and Turn Signal Lamp. The same ground circuit is used for both the Park and Turn Signal filaments in a dual filament lamp.
