The Jaltest JDC629A connects the 6-pin Deutsch diagnostic connector of installed engines to the 16-pin OBD2 port of your Jaltest diagnostic cable. On the engine side is a round connector with a light grey housing and a knurled coupling ring, behind which is a red sealing ring and six sockets in a circle. This is the Deutsch series associated with the SAE J1708/J1587 data bus; the cable is 28 to 30 cm long.

When connected to the cable, the Jaltest software accesses the engine control unit of the installed engine. The connection is not tied to a single manufacturer: Jaltest Marine covers, among others, the engine control units of Caterpillar, Cummins, Detroit Diesel, Iveco-FPT, John Deere, MAN, MTU, Scania, Volvo Penta, VM Motori and Yanmar. For twin installations, port and starboard appear as separate control units in the software. Coverage differs per engine control unit: for some it is limited to reading out and live monitoring, while for others parameters and reset are also included.

ADVANTAGES

✔Not tied to a single engine brand: the cable follows the 6-pin Deutsch connector rather than one manufacturer.
✔Connects to the connector associated with the SAE J1708/J1587 data bus, common on installed diesel engines.
✔Jaltest Marine covers the engine control units of various brands, including Caterpillar, Cummins, Detroit Diesel, Iveco-FPT, John Deere, MAN, MTU, Scania, Volvo Penta, VM Motori and Yanmar.
✔For twin installations, port and starboard appear as separate control units in the software.

POINTS TO NOTE

✕Only for the round 6-pin Deutsch connector; engines with a 9-pin Deutsch or a proprietary connection require a different cable.
✕What you can perform depends on the engine control unit: for some units it is limited to reading out and live monitoring, while for others parameters and reset are also included.
✕The throttle and reverse-gear control, the engine gateway and the helm control cannot be reached via this cable; those have their own connection.
✕The same 6-pin Deutsch connector is also found outside marine applications; for commercial vehicles, Jaltest provides the JDC211A for that purpose.

Applications and functionality

This cable is intended for workshops that read out installed engines with the Jaltest Link. Which version of the engine control unit you encounter and which functions go with it varies by brand and engine series.

Control units you can access

  • Engine control: Per brand and engine series.
  • Port and starboard: Separate for twin installations.

What you can do

  • Fault codes: Read and clear.
  • Measured values: In figures and graph.
  • Components and parameters: Where Jaltest provides them.
  • Service reset: Where a procedure is available.
  • Live monitoring: System values during operation.

How to use it

  1. Locating the connector: Find the round grey connector on the wiring harness.
  2. Connecting: Tighten the JDC629A onto the coupling ring.
  3. Link connection: Connect the OBD2 end to the Jaltest Link.
  4. Ignition on: Switch the ignition on.
  5. Reading out: Select the engine brand and engine series.

Compatible vehicles and applications

The connector determines compatibility, not the engine brand. This cable is for the round 6-pin Deutsch connector on the engine wiring harness of installed engines. The light grey housing with the red sealing ring shows whether you have the correct connector.

Installed diesel engines with 6-pin Deutsch:

  • Brands in the Marine coverage: Caterpillar, Cummins, Detroit Diesel, Iveco-FPT, John Deere, MAN, MTU, Scania, Volvo Penta, VM Motori and Yanmar.
  • Twin installations: Port and starboard as separate control units.
  • For example: the Cummins ECM CM850, with component control and parameters.
💡
Good to know: The 6-pin Deutsch connector is located on the engine wiring harness in the engine compartment, in some installations looped through to the helm. You can recognise it by the light grey round housing with the knurled coupling ring and the six sockets in a circle; the 9-pin Deutsch version has a visibly fuller pin field. Count the sockets in the connector before ordering.
