ACTIA MULTI DIAG CHINA INTERFACE VCI1 -> ORIGINAL ALMOST
The most important note- all here only for Actia Multi-Diag Interface bought from china with 2011 software.
* Big thanks toTITOUN, fantomel, Shami
Here you have original interface that was taken as reference:
Now, like this was my interface before any changes as it came form china:
- ESD protection for USB
2. Inductor
3. Inductor
4. Capacitor
5. Varistor
6. Common mode line filters
7. Pins for RS232 com portHere is the final result after changement, all pieces are in attachment:
All pieces you need to make changements are in xls attachment along with id from farnell and price. I hope like this i can help others improve their incomplete clones from china to have a proper interface.

And for repair to be complete look on 2nd board, back side:
B1 – 181 1812 180 ohms
B2 – 822 0603 8.2Kohms
B3 – 822 0603 8.2Kohms
B4 – EMPTY
B5 – 393 0603 39 Kohms
B6 – 9101 0603 9.1Kohms
B7 – 2401 0603 2.4Kohms
B8 – 822 0603 8.2Kohms
B9 – 822 0603 8.2Kohms
B10 – 822 0603 8.2Kohms
B11 – 822 0603 8.2Kohms
B12 – 2401 0603 2.4Kohms
B13 – EMPTY
U19 – EMPTY
and also rs232 pinout just in case
PSA CAN ADAPTER AC911807 PINOUT ; PN: AT 107 4095
ACTIA DB25 TO OBD2 AC911776 PINOUT PN: AT 530 4025 FROM ORIGINAL CABLE:
COMPLETE PINOUT FOR MULTIMODE CABLE MINI DIN 8P
This you will not find in china because like always, china does crap work on all clones and no one posted it until me.
This is my own:
ORIGINAL ACTIA MULTIDIAG OBD 1N/A MUX AC 911 907 PN: AT 107 4079 OR AT 107 4099
AC 911 862 PN: AT 107 4074 OLDER MODEL AC 965 401
AC 965 401 – ODB 1 MUX cables (PSA CAN, Ford CAN, Opel CAN, Rover air suspension)
With any of these adapters your interface VCI1 will be on same level as VCI2 but minus Bluetooth part Smile
So begin to search for AC911862, AC965401, AC911907 or by searching corresponding part numbers AT107 4074, AT107 4079, AT107 4099.
