Jaltest Steyr Engine 6-Pin Diagnostics Cable (JDC502A)

The JDC502A is the genuine Cojali Jaltest diagnostic cable for Steyr engines using a 6-pin diagnostic connector. Steyr engines power a range of agricultural tractors, industrial equipment, and specialty vehicles — primarily in European markets. If your shop services equipment with Steyr 6-pin engine diagnostic ports and runs the Jaltest AGV or OHW diagnostic system, the JDC502A is the specific cable required to connect your Jaltest Link interface to the engine ECU. At $230, it sits at the higher end of individual cable pricing, reflecting both the specialized application and the genuine OEM quality.

What This Cable Does

The JDC502A connects the Jaltest Link interface to Steyr engines equipped with a 6-pin diagnostic connector. Once connected, Jaltest software can communicate with the engine ECU for all supported diagnostic functions. Note that Steyr also has a 3-pin variant — the JDC501A ($185) — so confirm your engine's connector type before ordering.

Steyr Engine Diagnostics with Jaltest

Jaltest provides multi-brand agricultural and off-highway diagnostic coverage across 140+ brands. Steyr engines appear in older and specialty agricultural equipment distributed primarily in European markets.

The JDC502A makes that capability accessible on 6-pin Steyr engine configurations.
