Introduction To SWS Diagnosis
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The SWS reduces the number of wires by sending multiple signals along a single wire. This reduces vehicle weight and simplifies construction by reducing wiring harness complexity weight. The ETACS-ECU, front-ECU, column switch (incorporated in column-ECU) and sunroof motor assembly (incorporated in sunroof-ECU) have multiplex signal circuits that enable them to transmit and/or receive multiple signals and communicate with other control unit.
