    Educational Advantages:

  • Allows insertion of faults for the diesel engine systems with real problems, codes and other indicators.


  • Signals generated from most sensors that reproduce actual running conditions in the system.
  • Remote control using a dedicated software interface connected to a PC running WindowsTM through USB port.
  • Fault selection, signal variation (if available), and set intermittence parameters either directly or by remote hook up.

    Remote Control Software

  • Easy to install Windows®-based software allows you to control the fault box remotely via a USB cable (included with software) to your Windows® computer.
  • Allows you to program intermittent faults. Engine systems res- pond to created conditions and inserted faults with real world symptoms, OEM TC’s and check engine light operation.
  • Allows insertion of single or multiple faults in the engine.
  • Major engine sensor signals can be adjusted to produce a variety of engine operating conditions.
