scania coach/bus diagnostic port

[neilmch]

Would anyone know what the pin outs are on a 2003 scania k114 coach round diagnostic port? it has just 4 wires, positive power, ground, then 2 more (white wire, blue wire)

we thought they would be normal can hi/low but connecting these to pin 6 + 14 on the square obd2 lead still shows nothing.

Trying to get a VCi3 scania tool to read this coach

cheers

other 2 are k-line and l-line scania vci 2 works with this diagnostic socket, vci3 does not work
