Hi, thanks for all the information on canbus, on my sons D3 we had to jack up the rear to check the EPB to inspect access (nothing unplugged). When it was back on ground no crank and Christmas tree dash.
Now here’s my problem checking medium Cambus 60 ohms high & low line are both 2.5v positive to ground, high Cambus no resistance, no volts on high line and 2.5v positive on low line.
Anyone got any ideas.
Regards Ray

My guess,You have almost certainly disturbed a probably already delicate piece of wiring...likely around the connectors by passenger rear wheel or loom going to EPB itself.Look VERY closely at the cables whn inspecting!.....my break was approx 3 inch in from the connector amongst protective cover.
Good luck!

Thanks timmyt79,
I came up with that thought as canbus towards ABS is seeing good Voltages. Trying to find the fast canbus route and location of restraints module, I believe it comes from parking brake module then to restraints module and then to dashboard/OBD. Just trying to narrow down my search area. As I haven't found a diagram of wiring routing.

Well I have been chasing the wrong fault. Faulty OBD socket. Now I have 120 ohm. So brake in high speed + line at EPB. Starts now I have to find brake/ intermittent wire location and fix it before I track down Air ride fault.
