Hi all,

I have problem with OBC speedo/trip meter on my 965.
Here is the situation:
- speedometer works (pointer moves normaly)
- odometer in speedo counts Kms ok
- digital speedo and trip meter doesn't work (displays 0 always)

I checked connection between pin12 (obc) and pin2 (speedo) - ok.
I pulled out one wire from pin12 (obc) and while touching GND with it fast OBC shows the 'speed'.
So, my conclusion is that OBC is ok but the problem is somewhere else.
What unit produces signal for OBC?

Any help appreciated.
