Lexia 3 no communication with ECU Help

#1
Hi all,

I have one Lexia 3 which communicate with all control units except ECU engine. I measured

all relay but all OK. I dont know what is problem. I need any advice or at least

schematic. Lexia 3 is full with all IC. I tested other piece and communicate with ECU

engine OK.

Look forward your advance!
