Steyr engine 3 pin diagnostics cable

Jaltest Steyr Engine 3-Pin Diagnostics Cable (JDC501A)

The JDC501A is the genuine Cojali Jaltest diagnostic cable for Steyr engines using a 3-pin diagnostic connector. Steyr is an Austrian agricultural and industrial engine manufacturer — their engines appear in tractors, construction equipment, and specialty vehicles primarily in European markets. If your shop services Steyr-powered equipment and runs the Jaltest AGV or OHW diagnostic system, the JDC501A is the specific cable needed to connect your Jaltest Link interface to the 3-pin diagnostic port on these engines. At $185, it is a specialized cable for a specialized application.

What This Cable Does

The JDC501A connects the Jaltest Link interface to Steyr engines equipped with a 3-pin diagnostic connector. Without this cable, Jaltest cannot establish communication with 3-pin Steyr engine ECUs. Note that Steyr also has a 6-pin variant — the JDC502A ($230) — so confirm your engine's connector type before ordering.

Steyr Engine Diagnostics with Jaltest

Jaltest provides multi-brand agricultural and off-highway coverage across 140+ brands. Steyr engines are found in older and specialty agricultural equipment — their tractors were widely distributed across Europe and some export markets before the CNH Group consolidation. The Jaltest AGV kit (part number 29210, $4,500 MSRP) covers agricultural vehicle ECUs at dealer-level depth: fault code reading and clearing, live data monitoring, actuator tests, and where supported, calibration functions. The JDC501A makes that capability accessible on 3-pin Steyr engine configurations.

3-Pin vs. 6-Pin: Confirm Before You Order

Steyr engines come with different diagnostic connector configurations depending on the application and model year. The JDC501A covers the 3-pin variant; the JDC502A covers 6-pin. If you are unsure which connector your engine has, call us at 866-217-0063 and our tech team will help you identify the correct cable before you spend a dollar.
