CNH group switch diagnostics cable

Jaltest CNH Group Switch Diagnostics Cable — Deutsch 9-Pin (JDC511A)

The JDC511A is the genuine Cojali Jaltest CNH Group Switch Cable with a Deutsch 9-pin connector — the diagnostic switch adapter for Case IH and New Holland equipment that uses the Deutsch 9-pin connector configuration. Like its 13-pin sibling (the JDC507A), this cable is a switch adapter that routes the Jaltest diagnostic connection through the CNH platform's communication architecture. The Deutsch 9-pin variant covers a different subset of CNH equipment than the 13-pin version, so connector identification on your specific machine is important before ordering. The JDC511A is included in the Jaltest AGV USA Cable Kit, confirming its essential status for agricultural shops covering CNH equipment.

What This Cable Does

The JDC511A is a Deutsch 9-pin diagnostic switch cable that connects Case IH and New Holland equipment to Cojali Jaltest diagnostic software. It works as a switch adapter to properly route communication through the CNH vehicle bus architecture.

CNH Group Coverage and the Two Switch Cables

CNH Industrial manufactures New Holland Agriculture and Case IH equipment, with agricultural products spanning tractors, combines, hay equipment, and specialty harvesting machines. Different models within the CNH family use different diagnostic connector configurations — hence the need for both the JDC507A (13-pin) and the JDC511A (Deutsch 9-pin). The Jaltest AGV kit (part number 29210, $4,500 MSRP) covers all CNH platform ECUs at dealer depth: fault code access, live data, calibrations, injector coding, and DPF regenerations where applicable. The JDC511A's inclusion in the AGV USA Cable Kit means Cojali considers it an essential cable for agricultural shops.

Who Needs This Cable

Agricultural shops running Jaltest AGV who service Case IH or New Holland equipment with Deutsch 9-pin diagnostic connectors, CNH dealers and independent shops, cooperatives with mixed CNH fleets, and anyone building out their Jaltest AGV cable kit for full CNH coverage. If you already purchased the Jaltest AGV USA Cable Kit (70002013), the JDC511A is included. If you are building cables individually, you may need both the JDC507A and JDC511A depending on your CNH equipment mix.
