The OP-COM 1.99 interface functions as a multiplexer, automatically selecting the correct pin for communication with various vehicle control units.
Many clone interfaces lack proper K-line and CAN-bus switching. Try selecting “Manual” mode in settings or check wiring inside the OBD2 plug.
If you already own a clone cable and have an older laptop (or are comfortable with driver tweaks), OP-COM 1.99 provides incredible functionality for its price (often free aside from the cable). You can diagnose and even code many features that dealer tools charge hundreds for.
Not all interfaces are equal. Cheap $15 cables often have defective FTDI chips. Recommended are:
