The Jaltest JDC103A is an adapter cable that converts a 7-pin round connection (Wabco/Knorr-Bremse) to a 16-pin OBD2 port (J1962). The cable is intended for diagnosing trailers and semi-trailers equipped with brake and stability systems from Wabco or Knorr-Bremse. One end features a 7-pin round plug with a robust screw ring for a locked connection; the other end has a standard 16-pin OBD2 female connector that connects to the Jaltest diagnostic cable.
The cable enables communication between Jaltest diagnostic equipment and the electronic brake systems (EBS) and anti-lock braking systems (ABS) used by Wabco and Knorr-Bremse in trailer applications. Signals such as K-line are routed through the 7-pin diagnostic port on the trailer to the OBD2 interface of the diagnostic device. The robust design of the round connector with screw locking ensures a stable electrical connection during reading, even in workshop environments with mechanical stress.
