The Jaltest JDC528A connects the 8-pin diagnostic connector on stationary Volvo Penta engines to the 16-pin OBD2 port of your Jaltest diagnostic cable. On the engine side is a grey rectangular connector with eight contact sockets in two rows of four, a blue-green contact carrier, an orange sealing ring and a black locking bracket. The connector is located on or next to the engine. The black cable of 28 to 30 cm ends in an OBD2 shell marked JDC 528A, so you can find it in the case.
Via the cable, the Jaltest software reaches the engine control units EMS V3, EMS V4 and EDC, and the ACM V3 and ACM V4 exhaust aftertreatment units. For the engine control units, the coverage includes reading out as well as component control, parameters, calibration and reset; for the ACM units, calibration is not included. The cable works with the Jaltest Link V8.1 and V9 and falls under Jaltest Marine.

POINTS TO NOTE
Applications and functionality
The cable is intended for workshops that read out stationary Volvo Penta engines. The cable only passes through the communication lines; the main difference between the control units lies in the calibration.

- EMS V3: Engine control unit, full functions.
- EMS V4: Newer version, same functions.
- EDC: Diesel control unit, incl. calibration.
- ACM V3 and V4: Aftertreatment, without calibration.
What you can do
- Fault codes: Read and clear, with description.
- Measured values: Live monitoring while the engine is running.
- Components: Control on EMS, EDC and ACM.
- Parameters and reset: On all four units.
- Calibration: Only EMS V3, EMS V4 and EDC.
How to use it
- Check the connector: Locate the grey 8-pin connector on the engine.
- Connecting: Click the JDC528A into place with the bracket.
- Link connection: Connect the OBD2 end to the Jaltest Link.
- Ignition on: Switch the ignition on without starting the engine.
- Reading out: Select Volvo Penta and the engine series.

The four Volvo Penta cables side by side
Volvo Penta uses a different diagnostic connector per engine generation and per application, and each version has its own cable. The JDC527A and the JDC611A both have six pins but differ in shape and contacts. Only the JDC618A9 requires a Jaltest Link V9; the other three also work with V8.1.

- JDC528A (this cable): The same grey connector but wider, with eight contact sockets in two rows of four. Volvo Penta 8-pin connector on stationary engines: EMS V3, EMS V4, EDC, ACM V3 and ACM V4.
- JDC611A: Black oval connector, purple contact carrier with six pins in one row. Volvo Penta EGCI 6-pin and OBD-M: ECM EGC, MEFI and the EVC modules.
