Unhappy bmw e91 ccc professional Fail

Hello Everybody,

I need help for my bmw 320 e91 2005.
My CCC professional is dead, no radio, black screen...

see obd codes below :



Obd code : A731 JBE 30G-F is strange

First, I tried another used junction box (same parts number) = Nothing change.

Then, I tried another used bmw CCC (same parts number ) = Nothing change

CCC is never found on network ,what's happen ?

I can't try a programmation whit SSS or ISTA because CCC dosen't exis on network

No network = no coding

It's like if the JBE dosen't provide the+12V. First I need to check if I found the +12V on the fuse rear the CCC...

The screen (CID) it's working on DIS

Do you know any issue about the CCC wiring ?
E90 series have some problems with water leak inside the glove box (passenger side) no ?

No one have a731 obd code with a not working ccc ?

Thank you

i haven't got other bmw car with CCC

What I did :

I can't test the rear CCC fuse because the fuse is 'inside the main connector' when is plug.

someone told me the +12v is comming from the main connector (x13812) pin 15. It's a yellow / red wire.

With the multimeter, I found +0.07V...

If someone have I idea ?

Thanks

you need to try to replace bistable relay which enable 30G-F or whole front fuse assembly
keep in mind that they are have two versions - up to 03/2007 and after

fuse (it's number 31) is ok

bistable relay can't be replace, it's a 'generic meaning'

bisable relay is inside the juction box
I replace the junction by an other one but the problem is still present.

Maybe it's a K-BUS problem ?

same subject here :

http://www.iatn.net/techhelp/50/8269...-radio-and-nav

But I can't access...

please help me someone could help me ?

Thank you
