Valtra 16 pin diagnostics cable

Jaltest JDC520A - Valtra 16-Pin Diagnostics Cable

The Jaltest JDC520A is a genuine Cojali-manufactured 16-pin diagnostic cable designed to connect Valtra agricultural tractors to the Jaltest AGV diagnostic platform. Valtra is a Finnish-made tractor brand known in North America for its robust build and AGCO parentage — and like most modern tractors, it requires the correct proprietary connector to access the onboard electronics. The JDC520A provides that connection, giving technicians full Jaltest AGV software access for fault diagnostics, calibrations, and live data on Valtra machines equipped with a 16-pin diagnostic port.

What This Cable Does

The 16-pin connector on certain Valtra tractor models is not a standard OBD or Deutsch fitting. This cable bridges the gap between the Jaltest Link interface and the machine's native diagnostic port. With the JDC520A connected and the Jaltest AGV license active, you have the same access to Valtra's electronic systems that a dealer technician would use.

Who Needs This Cable

Shops and technicians servicing Valtra tractors — particularly the T, N, A, and S series models that use a 16-pin diagnostic connector — need this cable to connect to their Jaltest system. Valtra has a loyal following in dairy and grain farming operations, and independent ag shops that cover these brands need the right hardware to do the job without calling the dealer. If you already have the Jaltest AGV kit, this cable extends your reach to Valtra's 16-pin equipped machines.
