Since you seem to be the one with better answers, i write to you again to find out my problem. Maybe you could help and greatly appreciated.
My OBC, is completely blank, and when you click in the lever (The left one for the signal lights) generally I used to get all the same information as the OBC itself. My problem is that it is not simply working at all.
1. What I would like to know is Where they are connected together or if there is a fuse I am missing somewhere to feed them both??.
The capacitors changed was done about 6 month ago and doubt is related to this. The capacitor fix generally is when the speedo, or the counter resets itself, or language is change.
2. Is one of the capacitor is related to the OBC??
3. Do you know or anyone knows if there is a fuse somewhere else related to OBC??

Thanks for all the help!!!

The OBC and the gear selected indicator are two different things which are in no way related. The gear selected indicator probably just needs a new bulb in the instrument cluster.

None working OBC can be as simple as needing to replace the three backlite lamps or a blown fuse. I forget where the fuse is located (not main fuse box). Maybe someone can help here, but I believe it is located somewhere clandestine like behind the right kick panel.


I have kind of the same problem, except that sometimes it comes on after a while. Don't know what's the problem, but if the OBC needs replacing, I would just ignore it since they cost like a fortune. Would be great if someone knew how to fix this thing, it's kind of annoying when you start the car, not to be able to see in what gear you're in etc.


Thanks to all in advance for all the help keeping this old bmr running.

Problem: OBC no working at all, no light, nothing shows on the obc display or at the Cluster when click with the light lever.
Is there a fuse I dont know about?
Where is the connection behind the instrument cluster?
Do I have to remove it?
Please help!!
Car runs ok, no messages.
