Development
As mentioned before, the DCL Protocol is no publicly documented protocol. Therefore developing this board was a big challenge. Most information to start with comes from this project: https://github.com/babroval/ford-eec-iv-diagnostic
It was way easier to buy a cheap EEC IV ECU and develop with this, then testing everything against my car.
I used these Pins:
- 1 - 12V
- 37 - Ignition Power
- 57 - Ignition Power
- 20 - GND
- 40 - GND
- 60 - GND
- 18 - D+/A/OBD 3
- 19 - D-/B/OBD 11
