Since there is little information and review about the clone Actia Multi-diag Access J2534 Pass-thru, I decided to post my own experience.

Where I purchased the J2534 Pass-thru?

Multi-diag VCI 2013-Ⅱpass-thru (French version), € 239 no shipping included from diyobd2.fr (超链接)

How many days packed?

The package arrived at my door 4 days later. Package including VCI main unit, DB25 to OBD-2 Male cable, OBD2 OBD2 cable, DIN6 to USB cable and DIN6 to DB9F cable:

Day 1 after purchase:

First get the software installed and activated on a Vista Notebook by following the video installation guide:

But the device did not recognize the software. There was no communication between computer and device.
Then I contact the didobd2.fr dealer, the technician warns me to install Multi-diag VCI software on Window XP or Win 7 laptop. So I installed VCI on Virtual Machine running XP home acer laptop and it worked.

NOTE: It is very important to disable network and any anti-virus software programs before installing VCI.

Renault Clio was my first subject to observe, I connect the Multi-diag Pro to under the dashboard steering side OBD connector. It helped erase an engine code, reprogrammed mutlifunction steering angle sensor, code injector. Then VCI enabled to detect some parameters. Here are some pictures I taken. I figured out that actia multidiag can not only do some basic diagnosis, but also write it as the official tester ecu for any updates, drivers.


The first experience was successfully, but I realized that it ran slow than I imaged. So I decided to dissemble the device and check what the PCB inside look likes. I googled and found a little tutorial on MHHAUTO forum to modify the PCB to make it works faster. Here is the modified PCB.


Day 2 after purchase:

Second vehicle I tested was a BMW MINI 2011. One client took his car to my garage because the airbag light constantly flashed. I tested it with VCI but no code stored. I checked some other parameters and all fine. Then I disconnected the battery, and did a battery reset for half an hour. The
SRS light went off finally.



I have tested other vehicle models, Opel, BMW X5, Citroen C5, Pug 301, American Ford, Audi etc later, mainly French and American brands. I am not sure how it works on Japanese brands.

I still learning and testing other models and will add if necessary.
