The Jaltest JDC111A is the adapter connecting the 7-pin connector of the Knorr-Bremse KB4-TA trailer ABS to the standard 16-pin OBD2 interface of the Jaltest Link. The diagnostic connector is located on or near the ABS control unit, typically at the front of the chassis; the specific trailer or semi-trailer built around it doesn't affect the connection.
The cable opens the diagnostic line to the ABS Trailer (KB4-TA) control unit, the anti-lock braking system it's designed for. With it, Jaltest equipment reads fault memory and wheel speed sensors per axle, controls valves and modulators, and adjusts brake system configuration; some of these functions only become available with the separate Knorr-Bremse Diagnostics module (ref. 71502007). Trailers have never had a standardized diagnostic connector requirement, which is why this connector remains in use as long as the system is on the road. The cable falls under Jaltest CV (commercial vehicles).
