Auf Youtube gab es ein interessantes Video. J1850PW und J1850PWM Netzwerk Protokoll. EIn Anleitungsbuch zu dem im Video gesagtem gibt es auch hier zu finden: Anleitung J1850VPW / J1850PWM
Es ist auf Englisch, deshalb hier noch einmal den original Text für Euch:
PIN2 is the J1850 protocol terminal. The OBD2 data link connector or DLC is the central point for testing many automotive issues.
The DLC is a legislated part of OBD-2, which is a diagnostic system Federally mandated since year 1996.
All vehicles have the exact same connector after 1996 to present. This connector has not been changed. (note: the following is NOT a sales pitch.
