Jaltest JDC525A - Claas & Renault 14-Pin Diagnostics Cable

The Jaltest JDC525A is a genuine Cojali 14-pin diagnostic cable for Claas and Renault agricultural equipment. This is a distinct cable from the JDC519A — where that cable covers one connector type for these brands, the JDC525A covers the 14-pin variant. Claas and Renault use multiple connector configurations across their tractor and harvester product lines, and having the correct 14-pin cable is essential to establishing a reliable diagnostic connection with machines that use this port standard. If your Jaltest link cannot seat properly into a machine, you are not getting data — this cable solves that problem for 14-pin Claas and Renault equipment.

What This Cable Does

The JDC525A connects the Jaltest Link interface to the 14-pin diagnostic port found on certain Claas tractors, harvesters, and Renault agricultural equipment. Once seated, the Jaltest AGV software takes over — delivering full multi-system diagnostic access for supported models.

Claas and Renault Coverage — Why You May Need Both JDC519A and JDC525A

Claas is one of Europe's largest agricultural equipment manufacturers, with a lineup that spans combines (Lexion, Tucano, Avero), forage harvesters (Jaguar), and tractors (Axion, Arion, Elios). Renault also produced a significant agricultural tractor line, many of which are still in active service. Across these machines, multiple diagnostic port configurations have been used over the years. If you are servicing a mixed fleet of Claas and Renault equipment, you may need both the JDC519A and JDC525A to cover the full range of machines you encounter. The 14-pin JDC525A specifically targets equipment that does not use the standard connector covered by the JDC519A.

Diagnostic Capabilities With Jaltest AGV

With the JDC525A connected and the Jaltest AGV license active, technicians have access to:

• Fault code reading and clearing across engine, transmission, hydraulic, and body ECUs
• Live parameter data for active monitoring during operation
• Calibration and parameter setting functions supported for these brands
• Injector coding and aftertreatment functions on equipped machines
• DPF regeneration on emissions-equipped Claas and Renault equipment
