Have seen one of these there was bcm shorting to ground after some connection to it

what year, engine type, gearbox type. what display you had in the past. questions based on info required by tis to find out what is this code all about.

Its a 2009 1.3cdti 5 speed manual z13dtj. I had the normal clock display but upgraded to a gid

B3750 is not in the error list of the GID, sorry.

B3750 is not in the error list of the GID, sorry.

I know it's a board computer error code.

[liviu2004]

Maybe, but is not in the list. Also I do not know what you refer to board computer, there is no hardware device in your corsa d called board computer. That is actually a software function. Which sits in the display unit, called TID, MID, GID, CID, depends what you have.

Thats a bcm code not a display

That's what I said in my first post
I installed a gid changed the code index on tech 2 programmed it in.
After I was getting the dtc on the tech 2 b3750 board computer circuit open.
Yes this is in the bcm setting on the tech 2

Sorry for any confusion

As i told in my first replay bcm is shorting somwhere to ground
Any retrofitting done so far?
And if possible double check connector at gid side in case if any of pins bend down
