B-slash (`99 Disco 2 td5 LHD) error display

[bofhdk]

I'm quite desperate - after fiddling about under the dash my D2 has become quite unresponsive and is displaying a blinking B-with-a-slash in the odometer display.


(that was supposed to be 2 frame animated gif - imagine that the B-slash is flashing)

So far I've checked all the black leads for continuity to ground (all ok) and the Slate/pink lead from the fusebox/IDM to the BCU (also continuity).

I've swapped ECU, IDM & BCU for ones from a spares-vehicle (same model).

All to no effect.

Wipers, windows, hazards, key fob, central locking, ignition nothing ECU/BCU controlled works.

Headlights and horn do work though

Nanocom & Hawkeye both complain that they can't communicate with any ECU.

Are there any experts here that might be able to provide a fix?

Gahh - I finally found the error.

It turns out that I hadn't been diligent enough when checking fuses. In the cold darkness of my carport I missed that Fuse F13 in the engine bay was blown.

It turns out that this is where the BCU gets it's +12V - whithout which none of the other units work.

Now everything is back to normal

Good find and a good tip for everyone ~ fuses!



Thanks for the update.
