The Jaltest JSK02 is the service key for Liebherr: a 9-pin SUB-D plug with male pins, housed in a black plastic cover with two locking screws. You fit it to the designated connection in the machine, not to the diagnostic port of your equipment.

With the key in place, the machine switches to service mode and releases the diagnostic and adjustment functions; without the key, these remain locked. A separate version exists for Merlo, the JSK01. Within Jaltest coverage, Liebherr falls under Jaltest OHW; you connect the equipment using the diagnostic cable JDC542.9 or JDC551.9.

Advantages

✔Puts the machine into service mode, making the diagnostic and adjustment functions available.
✔Secured with two locking screws, so the connection stays in place while you measure.
✔Works with the Liebherr diagnostic cables JDC542.9 and JDC551.9 within Jaltest OHW coverage.
✔An original Jaltest item with reference JSK02.

Points to note

✕Not every Liebherr machine requires this key. Which models and years of manufacture are concerned is not specified; check this on the machine itself before ordering.
✕For Liebherr only. For Merlo there is a separate service key (JSK01); the two are not interchangeable.
✕Not a replacement for the diagnostic cable: you also need a Jaltest Link with a valid OHW licence and the corresponding Liebherr cable.
✕The key opens the service mode of the machine; it does not add any coverage or functions to the Jaltest software itself.

Applications and functionality

Service mode is the state in which a Liebherr machine releases its control units for maintenance. The key makes this mode possible; reading out and adjusting is then done with the Jaltest equipment.

What you need alongside it

  • Jaltest Link: Interface to PC or laptop.
  • OHW licence: Liebherr falls under Off-Highway.
  • Diagnostic cable: JDC542.9 or JDC551.9.

What you can do

  • Service mode: Put the machine into it.
  • Release functions: Diagnostics and adjustment possible.
  • Securing: Two screws hold it in place.

How to use it

  1. Fitting the key: Place the JSK02 on the connection in the machine.
  2. Securing: Tighten the two locking screws.
  3. Connecting the cable: Connect the Link via the JDC542.9 or JDC551.9.
  4. Starting the software: Open Jaltest OHW on the PC.
  5. Reading and adjusting: Select the Liebherr machine and continue.

Compatible machines and applications

The machine is decisive, not just the brand. Not every Liebherr machine requires this key, and this is not specified by model or year of manufacture.

Brand:

  • Liebherr: Machines within Jaltest OHW (Off-Highway).

Other version:

  • Merlo: Own service key JSK01, not interchangeable.
💡
Good to know: Whether your machine needs this key depends on the model and year of manufacture, and this is not documented per machine. Therefore, check first whether your Liebherr requires the service key before ordering.
