2. Terminal K = Bus of communication
3. Terminal L = Ignition for waking up car computing system (ECU: Engine Control Unit)
4. Existed 3 different protocols with same OBD2 connector incl. ISO/KWP, VPW, PMW
5. This K/L Diagnostic interface & cables work on ISO/KWP (Key Word Protocol) launched after 1996 only.
