The Jaltest JDC540A is a specialized adapter cable for diagnosing electronic and hydraulic control systems of Bosch Rexroth. This cable is indispensable for workshops servicing complex work vehicles. It is not tied to a single vehicle brand but focuses on the control system itself: the Bosch Rexroth controller for drive and hydraulics. The JDC540A connects the round 8-pin RS232 diagnostic port of the controller with the 16-pin OBD2 connector of your Jaltest system.

Without direct access to the controller, troubleshooting hydraulic issues, performing calibrations after repairs, and accurately adjusting machine functions are virtually impossible. The JDC540A is designed for demanding conditions and offers a reliable, interference-free connection during diagnosis and adjustment.


Application and functionality:

  • Direct system diagnosis: full access to Bosch Rexroth controllers for hydraulics, drive, and related systems.
  • Reading and clearing fault codes: reading and deleting Rexroth-specific fault codes.
  • Viewing live data: display of hydraulic pressures, pump and engine speeds, valve positions, joystick positions, and oil temperatures.
  • Calibrations and adjustments: performing crucial calibrations on pumps, valves, joysticks, and drive components.
  • Component testing: controlling and testing individual hydraulic valves (solenoids) for functional checks.

Suitable vehicles and applications:

To be used on any work vehicle equipped with a Bosch Rexroth control system.

  • Primary application: Diagnosis of machines with Bosch Rexroth hydraulic and/or drive systems
  • Industries and machine types:
    • Agricultural vehicles – tractors, combine harvesters, forage harvesters from various brands
    • Construction and earthmoving machines – widely used in, among others:
    • Excavators and mobile cranes (e.g. Liebherr)
    • Road construction machines such as asphalt milling machines (e.g. Wirtgen Group)
    • Concrete pumps
  • Municipal vehicles – specialized machines such as sweepers
