Hello!
Guys I need help with diagnosis my interface. I have full-chip version. At beginning it worked well with my Peugeot 407 and Diagbox 7.02. Now its connecting to PC and communicate with software well, but its not reading VIN number automatically and can't connect to any module. I'm only able to read engine fault codes. Checked this on another Peugeot 407 and it's behave the same. Checked also with Peugeot 307 (VAN version), worked perfectly.
So, I assume it's not the problem with car or software, but interface hardware problem. Assume that VAN bus and K-line bus work correctly, but something is wrong with CAN bus. Is that correct?

Where problem might be? Where to start looking for defect?
Edit: I forgot to say, I can hear some relays during car identify attempt.
