Would like to update this thread for members who may have K Bus issues in the future
When diagnosing a difficult K Bus fault I found this to be the best method
1) Locate connector co289 behind the driver kick panel, it is a grey connector taped to the main loom
2) Label the ten wires (white with a red line and yellow band) so they can go back ito the correct pin hole on the connector
3) Remove all ten wires, this is achieved by gently prising up the plastic and pulling the wire out
4) Insert pins 2, 3 and 4 which are the main K Bus interfaces IPK, LSM and BCU
5) Switch on the ignition and put the indicator stalk on left or right (You should have an indicator tell tale light on the dash)
6) Put each K Bus wire back into the connector one at a time in 20 second intervals (this gives the IPK time to test and realise there is a fault on that wire) When you place a wire in that has a fault the indicator tell tale on the dash fails to illuminate
