Hyundai Robex diagnostics cable

Jaltest JDC556.9 Hyundai Robex Diagnostics Cable

The JDC556.9 is the Cojali Jaltest interface cable for Hyundai Robex series excavators. The Robex lineup covers a wide range of Hyundai excavators — compact, mid-size, and large — and this cable connects those machines to the Jaltest V9 diagnostic platform for fault diagnosis, live data, and system analysis.

What This Cable Does

Connect the JDC556.9 between the Hyundai Robex diagnostic port and your Jaltest Link V9. The software communicates with the excavator's ECU to read engine fault codes, transmission codes, hydraulic system data, and aftertreatment information depending on the model year and system configuration. You can clear faults, monitor live parameters, and access the diagnostic data needed to make a confident repair decision.
