Each unit will have the K-bus on one of its connector pins. The wire colour code is white/red/yellow. You'll need a multimeter to check that the signal is there but it's not a straightforward "live" +12v. The aim is to discover which unit is responsible for a K-bus fault. As I said in my last post, there is a "header" which distributes the K-bus separately to all the high-line units but I was unable to find it on another member's tourer without dismantling a lot of the fascia. It wasn't behind the LCD screen where RAVE says it is.

You may need the help of T4 and an operator who is willing to spend time going through a logical fault-finding sequence to locate the faulty unit.
