ACTIA VCI USB DRIVER INSTALL
ACTIA VCI USB DRIVER UPDATE

The (PWR) LED will turn solid red to show the JLR VCI is powered. Connect the 2m USB cable to the JLR VCI and the other end to the SDD Laptop. Connect the J2534 device to the vehicle OBDII connector (the device powers from the vehicle).

My question is - why does Diagbox/Actia work once after installation and then never again. Drivers are available to install with JLR SDD DVD 142. There is no problem with the Actia - I have gone back to using my old trusty Sony Vaio/Lexia system with it and it works fine.

Open Device Manager-> I+ML ACTIA XS Device->PassThru XS USB Driver to check if driver is well. The Actia is, as before, recognised by the laptop and indicated as working properly in Device Manager so not a driver problem with Vista Browse folder to C:/ACTIA/Drivers VCI/PTIG. Subsequent tests in the C5 and the C4 resulted as before - no dialogue. Trying the system on the C5 everything worked well - but once again for the first time only. However the installation and activation were successful and, this time, everything runs much more rapidly with very quick load up and close down of the software. This runs Windows Vista which I appreciate isn't recommended for Diagbox. Save driver to C:/ACTIA/Drivers VCI/PT1G. Thinking that the fault might ultimately lie with the laptop, I managed to blag a more modern Acer from a friend and put Diagbox on this. PassThru+ XS USB Driver is a VCI (vehicle communication Interface) enabling you to communicate with the ECUs. Manually inputting VIN numbers also results in no dialogue with the cars. Whilst the software still loads and the HP recognises the Actia as operating normally, there has never been any further communication with the C5 and also my wife's C4 that I have tried it on. It identified the car VIN number and ran through the global tests no problem, dialogue with all ecu's being established. Although installation and activation were ultimately ok, the spec of the HP made Diagbox very slow to load and incredibly slow to shut down - about 15 mins.! However the first time I used it with my original Actia 9780.Z5 clone on my C5 it did work. I initially installed Diagbox 7.02 on a fairly ancient HP Pavilion laptop operating on XP Pro SP3.

So I decided to update to Diagbox from my venerable Lexia software that I have been using successfully for several years.
