Jaltest JDC601A — Yamaha Marine Diagnostics Cable

The JDC601A is a genuine Cojali Jaltest diagnostic cable that connects Yamaha marine engines to the Jaltest marine diagnostic platform. Yamaha is one of the largest outboard motor manufacturers in the world, and their engines are found on everything from small fishing boats to large offshore vessels. If your marine service shop runs Jaltest and services Yamaha-powered boats, this cable is what makes it possible.

The JDC601A covers Yamaha outboard, personal watercraft, and inboard engines. It is included in both the Jaltest Boat Cable Kit (70002008) and the Jaltest Outboard Cable Kit (70002010), which confirms its status as a core marine diagnostic cable for Yamaha coverage. MSRP is $70 from the official 2025 Jaltest pricelist.

What This Cable Does

Connected between your Jaltest interface and the Yamaha engine diagnostic port, the JDC601A enables:

• Fault code reading and clearing — read stored and pending DTCs from Yamaha engine ECUs
• Live data monitoring — view RPM, water temperature, fuel system data, throttle position, and other real-time parameters
• Marine-specific diagnostic tests available within the Jaltest Marine software platform
• Coverage for outboard, inboard, and personal watercraft Yamaha engines

Who Needs This Cable

Marine service shops, Yamaha dealers running Jaltest Marine, and independent technicians who service Yamaha-powered boats and personal watercraft. If you already have the Jaltest Marine license and routinely service Yamaha equipment, the JDC601A is a low-cost addition that unlocks Yamaha coverage on your existing platform. It is also the right choice if you are building a targeted outboard or boat cable kit rather than purchasing a full bundle.
