OBD-M diagnostics cable / Volvo Penta EGCI 6 pin

Jaltest JDC611A — OBD-M / Volvo Penta EGC 6-Pin Diagnostics Cable

The JDC611A is a genuine Cojali Jaltest diagnostic cable serving dual purpose: it is the OBD-M marine adapter cable and the specific interface for Volvo Penta EGC1 (EGC 6-pin) inboard engines. This cable connects MerCruiser Volvo Penta EGC1 inboard engines to the Jaltest marine diagnostic platform and is also listed in multiple Jaltest Marine cable kits as a core inboard connector.

Listed in the official Jaltest 2025 pricelist at $75 MSRP, the JDC611A is included in both the Boat Cable Kit (70002008) and the Inboard Cable Kit (70002009) — which tells you exactly the application this cable covers: inboard marine engines, specifically Volvo Penta EGC1 systems.
