For many years, the Data Link Connector or OBD was the location for important CAN bus data for aftermarket systems for many car brands. Not only diagnostic data but also Probe Vehicle Data. Until car manufacturers decided years ago to gradually phase out this. Fortunately, we made the right choice 25 years ago by not making ourselves dependent on the diagnostic bus or OBD. Our technology does not require an OBD to read data from all cars.
The table shows the declining role of the DLC in terms of the Probe Vehicle Data offering for a number of popular car brands. GREEN: data available on DLC. RED: data not available on DLC.
Our CAN products must be connected to Drive and/or Comfort buses, but never to a diagnostic bus. Even though we recommend the DLC as a connection point for our CAN interfaces in some car models, the diagnostic bus is not used. In some car models, drive and comfort buses are also available in the DLC, but this is becoming less and less. Where this is not possible, we simply recommend a different location in the car. We already did that and will continue to do so in the future. So that our CAN interfaces always work at the connection point that we recommend!
