J1939 back bone a9 diagnostics cable

Jaltest JDC216A9 -- J1939 Backbone A9 Diagnostics Cable

The JDC216A9 is a J1939 backbone cable built specifically for Cummins-powered equipment. If you're running a fleet of trucks, AGVs, or off-highway machines with Cummins engines, this is the cable that connects your Jaltest link to that unique triangular Cummins diagnostic port. At 11 inches long, it's a direct adapter -- not an extension -- designed to seat cleanly into the Cummins interface without adapters or workarounds.

Who Needs This Cable

This cable is required for shops and fleets working with Cummins industrial engines in off-highway applications -- construction equipment, agricultural machinery, automated guided vehicles (AGVs), and heavy trucks running Cummins powertrains. It is included in the Jaltest OHW USA Cable Kit and the Jaltest AGV USA Cable Kit, but if you're adding Cummins coverage to an existing setup, you can purchase it individually here.

What You Can Do With It

• Connect Jaltest diagnostic software to Cummins-powered trucks, AGVs, and off-highway equipment
• Read and clear fault codes via J1939 backbone
• Access live data streams from Cummins engine ECMs
• Perform diagnostic functions supported by Jaltest OHW and AGV software modules
• Compatible with the full range of Cummins industrial engine applications supported under V9 link

Compatibility Notes

Requires Jaltest Link V9 hardware and a valid Jaltest OHW or AGV software license. This cable is not a standalone diagnostic tool -- it works as part of the Jaltest system. If you're unsure whether your current Jaltest kit covers Cummins OHW, call us before ordering.
