*DoIP (Diagnostics over Internet Protocol)
Diagnostics over Internet Protocol is a communication protocol that is already installed in some vehicle models and will increasingly be used in future vehicle models. This means that our DoD 2.0 will also be used in the latest vehicles.
**CAN FD (Controller Area Network Flexible Data-Rate)
The Controller Area Network Flexible Data Rate is an extended CAN bus communication standard, which will also be used in new vehicle models. Thanks to the ability to process this communication protocol, our DoD 2.0 remains suitable for use for even the latest vehicles.
