Econtrols diagnostics cable (note: JDC100 is needed to use this cable with the v9 link)

Jaltest JDC544A EControls Diagnostics Cable

The JDC544A is a genuine Cojali Jaltest diagnostic cable for connecting EControls-equipped off-highway and material handling equipment to the Jaltest diagnostic system. EControls is a widely used engine management and control system found in a range of specialty and industrial equipment — this cable is the physical interface you need to run Jaltest diagnostics on those machines.

What This Cable Does

Plug this cable between the EControls diagnostic port on the machine and your Jaltest Link interface. Once connected, Jaltest software can communicate with the EControls ECU to read fault codes, clear DTCs, view live sensor data, and perform calibrations or resets depending on what the system supports.

Key Specifications

• Part Number: JDC544A
• Compatible Equipment: Off-highway and material handling equipment with EControls systems
• Jaltest Link Compatibility: V8.1 and V9
• Cable Length: Approximately 11 inches
• Important Note: JDC100 extension cable is required when using this cable with the Jaltest Link V9
• MSRP: 15.00 (Cojali USA 2025)

The JDC100 Requirement

If you are running the Jaltest V9 Link, you must also have the JDC100 extension cable (sold separately). The JDC544A connects directly to V8.1 without the adapter, but V9 requires the JDC100 in the chain. This is a standard requirement across several Jaltest specialty cables — make sure you have JDC100 in your kit before ordering if you are on V9.

Who Needs This Cable

This cable is for technicians and shops that service EControls-equipped machines. If you run a fleet of off-highway equipment or work in material handling, and you use Jaltest as your primary diagnostic platform, this cable extends that coverage to EControls systems. Without it, Jaltest has no physical path to communicate with EControls ECUs.
