CDA6 J2534 Bridge FAQ
What does the DUBB45 CDA6 J2534 Bridge do?
It provides a bridge between CDA6 and a compatible J2534 pass-thru interface installed on the same Windows computer. It does not replace CDA6 or the manufacturer driver for your J2534 hardware.
Does every J2534 device work?
Compatibility depends on the device, its driver, Windows configuration, and the communication features required for the job. Not every device or protocol is guaranteed. Always test communication safely before attempting programming.
Why does Windows show a security warning?
Windows may warn about newly downloaded or unsigned applications. Download only from this official DUBB45 page, verify the SHA-256 checksum shown above, scan the ZIP with your security software, and do not run a copy received from an unknown third party.
