The DAD-C1 vehicle communication interface
The DAD-C1 is a Vehicle Communication Interface (VCI). It is used with the existing Crypton CCP emissions range to deliver engine speed (RPM) into the Diesel MOT emissions test routine quickly and accurately.

The Crypton program for DAD-C1 also features complete EOBD reading capability for EOBD equipped vehicles, generally petrol vehicles from 2001 and diesel vehicles from 2004. This covers the standard EOBD modes and includes current powertrain diagnostic data, DTC read and clear, powertrain freeze frame data and oxygen sensor monitoring test results.

With high demand in workshops after the MOT extension ended, the DAD-C1 is a great solution to make the process as painless as possible to ensure efficiency, accuracy and reliability of results.

Available to purchase with Crypton's Emissions Tester or as an upgrade option to your current Crypton Emissions Tester (T&Cs apply). More info…

Your emissions tester PC should be on Windows 10.

Press the windows logo key at the bottom left hand corner of your screen. Type winver in the open box and then select OK. The version will then be displayed.

If you have a Windows 7, you may be able to upgrade the operating system to Windows 10 instead of replacing it. To check if your current PC can be upgraded to Windows 10, please visit https://www.microsoft.com/en-gb/ If your PC is older than Windows 7, you will have to replace it with a Windows 10 PC.

Windows ended the life of Windows 7 in January 2020. This means there is no longer any security support from Microsoft, which means Windows 7 PCs and any versions before are at risk of being hacked. We therefore highly recommend upgrading or replacing your PC to Windows 10.

Please call your Crypton Area Sales Manager or your local Crypton distributor.

crypton 2 post lift testimonial by k&s

"I’m really happy with my new VCI device.  Being able to obtain RPM and oil temperature readings speeds up our emissions test considerably. We also found the added feature of the ECU fault code reader a real benefit to our business.  It’s a great little tool!!."
