Yanmar 3 pin diagnostics cable

Jaltest JDC612A — Yanmar 3-Pin Diagnostics Cable

The JDC612A is a genuine Cojali Jaltest diagnostic cable designed to connect Yanmar marine outboard and inboard engines with a 3-pin diagnostic connector to the Jaltest marine diagnostic platform. Yanmar is a major manufacturer of marine diesel engines, particularly known for compact, reliable inboards and diesel outboards used in sailboats, small cruisers, fishing vessels, and commercial marine applications. The JDC612A is the specific cable required for Yanmar engines equipped with the 3-pin diagnostic port.

Listed in the official Jaltest 2025 pricelist at $70 MSRP, the JDC612A is included in both the Boat Cable Kit (70002008) and the Inboard Cable Kit (70002009).

Who Needs This Cable

Marine service shops and technicians servicing Yanmar-powered boats. Yanmar diesel inboards are enormously popular in the sailboat and cruiser market — they are often the standard inboard choice for production sailboats from 25 to 50 feet. If your shop handles sailboat and small powerboat service, Yanmar engines will be a routine sight. The JDC612A lets you diagnose them on Jaltest rather than needing a separate Yanmar diagnostic tool.
