The Jaltest JDC611A connects the 6-pin EGCI diagnostic connector of Volvo Penta petrol engines to the 16-pin OBD2 port of your Jaltest diagnostic cable; the same cable serves the OBD-M version. On the engine side is a black oval plug with a locking bracket and a purple contact holder with six gold-plated pins in one row. The cable measures 28 to 30 cm.
The cable opens the diagnostic line to the engine management and the EVC network on board: the ECM EGC, the older MEFI 1-2 and MEFI 3-4, the EVC modules EVC-C and EVC-MC, the HIU instrument panel, the HCU multiplex, the PCU drivetrain and the SCU steering control. On the EVC-C and EVC-MC you only get ECU data, parameters and, on the EVC-MC, calibration. The cable falls under Jaltest Marine.

- EVC-C and EVC-MC: Parameters, no fault codes.
- HIU (EVC): Instrument panel.
- HCU (EVC): Multiplex.
- PCU (EVC): Drivetrain.
- SCU (EVC): Steering control.
What you can do
- Fault codes: Engine and EVC modules.
- Measured values: Live monitoring with the engine running.
- Components: Actuators of the engine management.

- JDC528A: The same grey plug but wider, with eight contact sockets in two rows of four. For the 8-pin connection on stationary engines: EMS V3, EMS V4, EDC, ACM V3 and ACM V4.
- JDC611A (this cable): Black oval plug, purple contact holder with six pins in one row. For EGCI 6-pin and OBD-M: ECM EGC, MEFI and the EVC modules.
- JDC618A9: White rectangular plug with two round contact sockets, red and black wire. For Volvo Penta KAD/KAMD/TAMD with 2-pin connector.
