What is a “muxed” Pug?
Despite what it sounds like, this is not a mixed breed of dog 🙂 Mux is an abbreviation for Multiplexed. The PSA group (which includes Peugeot and Citroen) introduced multiplexing to their cars in 2001. A multiplexed car relies on fewer wires (up to 30% less) to accomplish the same tasks. It achieves this by sending different signals down the same wire for different components, each component knows what signal to listen for and ignores the others. This saves considerable weight in the car and its wiring loom can thus be smaller, lighter and less expensive. A BSI (Built-in Systems Interface) controls several different networks operating comfort, safety and mechanical equipment through a the single multiplex circuit. The BSI prioritises all the information coming to it so that, for instance, safety matters take precedence when necessary. A further advantage of the multiplex wiring system is improved theft protection. The 206 immobilizer system incorporates mutual interrogation between th
