The Jaltest JDC217.9 is the cable for machines with the standardised 9-pin Deutsch diagnostic connector type 2. On the machine side is a green round connector with a black coupling ring and nine sockets; on the other end is a 26-pin DB26 connector with a screw flange, which plugs directly into the port of the Jaltest Link V9. As a result, you do not need an OBD2 intermediate cable. The cable is 147.5 to 152.5 cm long.
SAE J1939 defines both the message structure and the diagnostic connector. This connector comes in two versions: the black type 1 for the slower bus and the green type 2 for the faster one, and this is the green one. Because the connector is standardised, the same cable works on agricultural machines, construction machines, internal transport and marine engines. The cable is covered by Jaltest AGV, OHW, MHE, Marine and Multi-Purpose Vehicle.
ADVANTAGES
POINTS TO NOTE
Applications and functionality
Via the standardised 9-pin Deutsch connector you can access the data network of the machine. What is on it is not a fixed list: a tractor has different units than a excavator or a marine engine. What you can carry out depends on the Jaltest module the machine falls under.
Control units you can access
- Engine control: Typical participant.
- Transmission control: Typical participant.
- Other units: Varies by brand and type.
- Per segment: Same connector, different units.
What you can do
- Fault codes: Read and clear after repair.
- Measured values: Monitor sensor values live.
- Components: Activate and test actuators.
- Parameters and calibrations: Where Jaltest offers them.
- Maintenance resets: Where Jaltest offers them.
How to use it
- Check the connector: Locate the green 9-pin connector.
- Connect: Plug the JDC217.9 in and tighten the coupling ring.
- Link connection: Screw the DB26 end onto the Link V9.
- Ignition on: Switch the ignition on without starting the engine.
- Read out: Select make and model in the correct module.
Compatible vehicles and applications
The connector determines compatibility, not the brand. The cable is for the standardised 9-pin Deutsch connector type 2 and not for a machine brand. SAE J1939 prescribes the connector, so manufacturers do not deviate from it.
Application:
- Agricultural machines (AGV): With a green 9-pin Deutsch connector.
- Construction and off-road machines (OHW): The same standardised connector.
- Internal transport (MHE): The same standardised connector.
- Marine engines (Marine): J1939 also prescribes the same connector there.
- Multi-Purpose Vehicles: J1939 also prescribes the same connector there.
