it depends of the generation of the car
can be KWP2000 over TP2.0, KWP2000 over TP1.6, UDS over ISO transport protocol (CAN), KWP1281 or KWP2000 over K-Line

Electrical interface for kwp2000 on k line is the same as for iso 9141 (kw1281).
However, there are vehicles that have some modules connected to the l-line as well.
