Whether you’re servicing Deutz, Cummins, Kubota, or Volvo systems, these cables are must-haves for any technician looking to do the job right.
1. JDC504A – Deutz Engines Diagnostic Cable
If you’re servicing Deutz engines, this is the cable you want in your toolbox.
The JDC504A cable allows for precise diagnostic access to Deutz diesel engines when used with your Jaltest diagnostic tool. It’s purpose-built to interface directly with Deutz ECUs, making it ideal for off-highway and industrial applications where these engines are commonly found.
💡 Perfect for: Heavy-duty mechanics working on Deutz-powered equipment in agricultural, construction, or industrial settings.
2. JDC216A9 – J1939 Backbone A9 Diagnostics Cable
Whether you’re troubleshooting communications on a complex J1939 network or diagnosing a stubborn CAN issue, the JDC216A9 cable is your go-to tool.
This cable allows you to connect directly to the backbone of the J1939 network, bypassing inline components and giving you clean, uninterrupted access for diagnostics. Designed with a 3-pin “A9” connector, it’s indispensable for technicians needing to isolate and test network integrity without interference.
It is also a key cable for Cummins engines, particularly when diagnosing vehicles using a J1939 backbone. If you’re working on Cummins-powered trucks or equipment, this adapter provides the reliable access needed for full ECM communication.
💡 Perfect for: Techs performing advanced diagnostics or CAN communication testing on Cummins engines, commercial vehicles, and heavy-duty equipment.

This diagnostic cable is designed specifically for Kubota industrial engines and connects with your Jaltest tool to run full diagnostics, retrieve fault codes, and perform system tests. Whether you’re in agriculture, groundskeeping, or light construction, this cable simplifies service tasks and reduces downtime.
💡 Perfect for: Off-highway equipment specialists working on compact tractors, UTVs, and industrial Kubota-powered systems.
