Massey Ferguson and SISU engine diagnostics cable

Jaltest Massey Ferguson and SISU Engine Diagnostics Cable (JDC518A9)

The JDC518A9 is the genuine Cojali Jaltest diagnostic cable for Massey Ferguson equipment with SISU (AGCO Power) engines, with the A9 designation confirming V9 Link compatibility. SISU engines — now branded as AGCO Power — are Finnish-made diesels used extensively across the AGCO family: Massey Ferguson, Valtra, and Fendt all use AGCO Power engines in significant portions of their lineups. This cable is distinct from the JDC513A (standard Massey Ferguson cable, $100) — the JDC518A9 is specifically for the SISU/AGCO Power engine ECU, which requires a different diagnostic connection. If you are diagnosing MF equipment with SISU engines and the standard MF cable is not connecting to the engine ECU, the JDC518A9 is what you need.

What This Cable Does

The JDC518A9 connects the Jaltest Link V9 interface to Massey Ferguson tractors and equipment powered by SISU (AGCO Power) engines, enabling engine ECU-level diagnostics via Jaltest AGV software.

SISU Engines and the AGCO Power Platform

AGCO Power (formerly SISU Diesel) manufactures diesel engines ranging from 4 to 9 cylinders, from approximately 75 to 400+ horsepower. These engines are used as the primary powerplant in Massey Ferguson's mid-to-high horsepower tractor lineup, and also appear in Valtra and some Fendt models. They are notable for their Scandinavian engineering — robust, efficient, and electronically sophisticated, requiring proper diagnostic tooling for accurate ECU access. The Jaltest AGV kit (part number 29210, $4,500 MSRP) covers AGCO family brands at dealer depth, and the JDC518A9 provides the specific SISU engine diagnostic connection.

Do You Need Both the JDC513A and JDC518A9?

Potentially yes, depending on what you need to diagnose. The JDC513A ($100) connects to the general Massey Ferguson platform; the JDC518A9 ($155) specifically targets the SISU engine ECU. For complete MF coverage — vehicle platform and engine — you may need both.
