The Jaltest JDC103A Adapter Cable forms the physical bridge between the specific 7-pin diagnostic port of Wabco and Knorr-Bremse brake systems and the standard 16-pin OBD2 connector. This cable is specifically designed for accessing electronic brake systems (EBS and ABS) on towed equipment, such as trailers. This physical connection between the vehicle-specific connector and the diagnostic hardware enables in-depth data communication with the brake system control units.
Technically, the cable functions as a pass-through adapter that accurately translates the pin-out of the 7-pin connector to the OBD2 standard, without loss of data speed or signal integrity. This guarantees stable signal transmission via the correct communication protocols used by the brake manufacturers. Because the internal wiring is specifically tailored to the hardware architecture of this brand, this cable is only compatible with Jaltest diagnostic equipment and cannot be used with third-party interfaces.
ADVANTAGES
KEY POINTS
Applications and functionalities
