Hello everyone,

Can someone give me a hint?
'CAN-dongles allow you to record basic driving data (engine speed, speed, pedal position, temperature, etc.) via OBD2, essentially by querying the standard parameters.'
7DF# 02 01 xy ...
J1962 OBD2 connector, pin 6/14: CAN high/low.
This works perfectly for all (newer) passenger cars, but not for the Sprinter W906 manufactured in 2016?
'At the specified pins 6 and 14 on the J1962 connector, there is definitely some signal activity via the 11-bit/500k protocol, but the 7DF queries (as well as the 29-bit queries) are not being answered.'
Ich dachte, diese Abgas-relevanten Daten müssten zwangsweise abfragbar sein, oder gilt das nur für 'richtige' PKW? ASure, here are some new ideas:

* **Create a new product or service.** This could be something that solves a problem for people, or it could be something that is simply fun and enjoyable.
* **Start a business.** There are many different types of businesses you can start, from small online stores to large corporations.
* **Invest in real estate.** Real estate can be a good way to build wealth over time.
* **Learn a new skill.** Learning a new skill can open up new opportunities for you, both personally and professionally.
* **Travel the world.** Traveling can broaden your horizons and help you learn about different cultures.

These are just a few ideas to get you started. There are many other possibilities out there, so don't be afraid to explore and experiment!

Thank you and best regards.

ID 7DF represents functional addressing.

Depending on the protocol used (KWP2000 or UDS), the functional request provides the physical addressing of each control unit.

For devices relevant to the OBD standard, the addresses are predefined according to ISO 15765-4.
