Jaltest JDC304A -- Wabco ATC Diagnostics Cable

The JDC304A is built for diagnosing WABCO Automatic Traction Control systems. WABCO ATC is found on a wide range of heavy commercial vehicles, and the JDC304A gives your Jaltest link a direct connection to those systems through its 16-pin to 9-pin cable configuration. At 11 inches, it is a direct adapter rather than a long diagnostic cable -- it seats the Jaltest link directly at the WABCO ATC diagnostic port.

Who Needs This Cable

Fleet shops and heavy-duty service centers working on vehicles equipped with WABCO ATC systems.

It also serves as the cable for WABCO MTS diagnostic access, giving you dual-application value if your fleet includes vehicles using either WABCO system.

Compatibility Notes

The 16-pin to 9-pin configuration is specific to the WABCO ATC diagnostic interface -- do not confuse the 16-pin here with a standard OBD-II port. Requires a valid Jaltest software license covering WABCO ATC systems. Compatible with V8.1 and V9 link hardware.
