[Warning Light] U0140 after upgrade to second hand radio

[mikeh79]

Hello
After i upgraded to second hand radio i get fault U0140 Lost Communication With Body Control Module, and  also a yellow check engine came on and stays on .


I read somewhere that the fault code is pretty normal when upgrading to another headunit that is not official, maybe someone knows about this.

But i have no idea if  fault U0140 would activate the yellow engine symbol, maybe some of you would know this, or the faultcode and yellow engine symbolis two different causes?

Everything in the car seems to be working as before

The Teyes radio i bought  send uses a canbus descrambler to get information from the canbus and comes with a OBD 2 canbus reader .

Regards

While I cannot help with your specific problem with your fault code. One thing that I thought I should point out from your post is that the Berlingo M59 model does not use CANBUS but uses a simpler/earlier version called VANBUS which maybe is not compatible with your new radio?
