Is your device recognised by the computer?
Have you used it successfully previously?
Can you use it on other Citroen or Peugeot models?

Your device might not be a Full Chip, some of which do not work on Citroen C5 and Peugeot 307. Or it may be a connector problem, it is not uncommon to have bad connection due to bad soldering.

Ensure that your software is properly installed and the drivers (in the Device Manager) recognise the device when you insert the USB to the computer.

Make sure you input the proper RPO when starting DiagBox, inputting the wrong numbers may result in ECU devices not recognised.

The driver is installed, PC VCI conect ,diabox also communicates with the VCI (chattering relays) diabox responds computer does not communicate! Testing Peugeot 807 2003 Váci new, is unused.

By the way, does it read the VIN?

Try Citroen C8 and enter a relevant RPO like (9876 is 23 November 2003).

Check the solder points where the cable enters the VCI you may have one or more wires not properly soldered.

Not read vin.
connection with the car and said the computer does not correspond!
In the evening I check those connections to the VCI.
When communicating with wirless car should be on or off?
Thank you for answer.

Wifi and Network connectivity do not affect VCI communication through USB. But people prefer to have them off in case DiagBox gets locked.

I checked the connections and everything ok.
Can not I have a problem with the installation or upgrade? I do not know what to try

[Simple]

I can see that your device does not have the TDK filter and missing a number of optocouplers!!. It is possible that it does not communicate with Peugeot 307 and Citroen C5. To confirm, try another Peugeot or Citroen model and see if it works.

It is not very clear, but one of the NEC relays legs (Bottom left) seem not soldered properly, check all of them.

Hello, today I checked connections to NEC and some joints seems wrong. (cold junction) overflights!
I also tried to install xp sp3 and the same problem.
The connection probably follows (relays Chattering) without any response from the control units.
to fix'll let you know if it helped.
Thank you.

Hi, I tried on another car.
307 2003 communicating (I assume I do not have a full clip)
207 2008 communicates
Why can not communicate with my 807?

Errr.... I have downloaded 4 files to get lexia/etc but how do I unpack them?

they are called DBV0702.zip.001 to DBV0702.zip.004 and if I rename them to DBV0702 001.zip to DBV0702 004.zip unzip says it can't unpack them, the folders are empty (286 mb each)

where do I go wrong?
