Claas, Renault diagnostics cable

Jaltest JDC519A - Claas & Renault Diagnostics Cable

The Jaltest JDC519A is a genuine Cojali-manufactured diagnostic cable that connects Claas and Renault agricultural equipment to the Jaltest diagnostic platform. If your shop services Claas harvesters, combines, or Renault-powered tractors and ag equipment, this is the cable that bridges your Jaltest link to those machines. Without the right cable, your Jaltest system simply cannot communicate with these brands — the JDC519A is the missing piece for shops that need full coverage on this segment of European agricultural iron.

What This Cable Does

The JDC519A provides the physical and protocol connection between the Jaltest Link interface and the diagnostic port found on Claas and Renault agricultural machines. Once connected, technicians can access all the diagnostic functions that Jaltest AGV software supports for these brands: reading and clearing fault codes, viewing live sensor data, performing calibrations and adjustments, and more.

• Compatible brands: Claas and Renault agricultural equipment
• Compatible Jaltest modules: Jaltest AGV (Agricultural Vehicles) — works with Jaltest Link V8.1 and V9
• Genuine Cojali product: Manufactured by Cojali, the same company that makes the Jaltest diagnostic system — not a third-party aftermarket cable
• Listed in Jaltest 2025 Pricelist: Part number JDC519A, MSRP 55.00
• Professional grade construction: Built for daily shop use, not a consumer-grade adapter

Who Needs This Cable

This cable is a targeted purchase for a specific need. If you are running the Jaltest AGV kit and working on:

• Claas Lexion, Tucano, Avero, or other Claas combine and harvester models
• Claas Axion, Arion, or other Claas tractor lines
• Renault-branded agricultural tractors and equipment

...then this cable is required to establish the diagnostic connection. Shops that specialize in European agricultural equipment or serve grain and crop farming operations are the primary buyers. Equipment dealers and independent ag repair shops servicing these brands should have this cable on hand before a machine rolls into the bay.

How Jaltest AGV Works With This Cable

The Jaltest AGV software platform covers over 140 agricultural brands, including John Deere, Case, Kubota, New Holland, and others. For Claas and Renault machines specifically, the JDC519A is the adapter that completes the connection. Your Jaltest Link interfaces with the laptop or tablet running the Jaltest software via USB; the JDC519A goes from the Link interface to the machine's diagnostic port.

With this cable connected and the AGV license active, technicians gain access to:

• Fault code reading and clearing across all accessible ECUs
• Live data streams for engine, transmission, hydraulics, and other systems
• Calibration and parameter setting functions where supported by the OEM
• Injector coding capabilities (where applicable)
• DPF/aftertreatment regeneration functions on equipped machines
