Liebherr rectangular 6 pins diagnostics cable (note: JDC100 is needed to use this cable with the V9 link)

Jaltest JDC551.9 Liebherr Rectangular 6-Pin Diagnostics Cable The JDC551.9 is a specialized Cojali Jaltest diagnostic cable for Liebherr trucks and buses. Liebherr uses a distinctive rectangular 6-pin diagnostic connector on certain models — this cable provides the physical interface between that connector and the Jaltest diagnostic system, enabling full ECU communication for fault diagnosis and system analysis. Cable Construction Unlike most Jaltest specialty cables that run about 11 inches, the JDC551.9 is 1.5 meters (approximately 5 feet) long. This extra length is practical when working around large Liebherr trucks and buses where the diagnostic port may be positioned in a tight or hard-to-reach location. One end features a 21-pin connector that interfaces with the Jaltest system; the other end has the 6-pin rectangular connector that plugs into the Liebherr machine.
