Jaltest Extension Cable SUBD-26 + Jack — JDC100

The Jaltest JDC100 Extension Cable (SUBD-26 + Jack) is a genuine Cojali accessory cable that extends the reach of your Jaltest Link diagnostic interface. At $100, this cable is part of the standard Jaltest accessory lineup and serves as a critical adapter for several specific diagnostic cables that require it when used with the Jaltest Link V9. If certain specialty cables in your kit are flagged as needing JDC100 to work with the V9 link, this is the piece that makes them compatible.

What This Cable Does

The JDC100 extension cable features a SUBD-26 connector with a jack, extending the connection between the Jaltest Link interface and the vehicle-side diagnostic cable. It is not a brand-specific connector — it functions as an interface extender in the Jaltest system, particularly required for compatibility with certain specialty cables when used on the V9 platform.
