AC problem Lexia tested
#1
       
Hi to all !

I am looking for clue where to look in the BSI pcb.

AC do not working , AC clutch isn't engage.

New compressor installed. the old compressor clutch bearing was released/brake. maybe make a short circuit.
System gas checked and full.
All fuses was checked and found ok.
BSM was changed.

After all of those I connect the car to a diagnostic cable and run Lexia.

Testing the BSI found one error (attached).

But I don't have any idea where to start when looking for this short circuit in the BSI pcb.
Can anyone help ? I just need a starting clue / idea. Huh

Citroen Berling 2008 1.6HDI disel 5 speed.

Would like to help but unfortunately my understanding of management systems is zero. I could only suggest finding the relay which supplies the air-conditioning clutch, checking there is a main supply there then wiring in your own switched live to trigger it.
