Jaltest JDC618A9 — Volvo Penta KAD/KAMD/TAMD (A9) Diagnostics Cable

The JDC618A9 is a genuine Cojali Jaltest diagnostic cable for Volvo Penta KAD, KAMD, and TAMD series marine diesel engines, compatible with the Jaltest Link V9 interface. These engine families represent some of Volvo Penta's most capable and widely deployed diesel inboard marine engines — turbocharged and intercooled units used in express cruisers, sport fishermen, and commercial vessels. Getting diagnostic access to these engines requires the correct cable, and the JDC618A9 is it.

Listed in the official Jaltest 2025 pricelist at $110 MSRP, the JDC618A9 is included in multiple Jaltest Marine cable kits: the Boat Cable Kit (70002008), the Inboard Cable Kit (70002009), and notably the Jet Ski Cable Kit Without Yamaha (29985) — which reflects Volvo Penta's presence across a broad range of watercraft applications.

Understanding the KAD/KAMD/TAMD Engine Families

Volvo Penta has produced these diesel series for decades, and they remain common in the marine service market:

• KAD — Turbocharged and intercooled Volvo Penta diesel, naturally aspirated base
• KAMD — Turbocharged and intercooled marine diesel with drive output
• TAMD — Turbocharged marine diesel, widely used in commercial and recreational vessels

These engines are found in an enormous number of boats that are still actively in service, and they require electronic diagnostic access to properly diagnose fuel system, emissions, and control system faults.

What This Cable Does

The JDC618A9 enables Jaltest diagnostic communication with Volvo Penta KAD/KAMD/TAMD engines, providing:

• Fault code reading and clearing — access stored and active DTCs from Volvo Penta engine ECUs
• Live data monitoring — view boost pressure, fuel system data, engine temperatures, RPM, and other parameters in real time
• Marine inboard diagnostic functions within the Jaltest Marine platform

• Boat Cable Kit — Part Number 70002008 ($880 MSRP)
