The easier way to test complex electronics

  • Intelligent and with a secure future due to internal OBD-exchange adapter
  • Software-controlled by ESI[tronic]
  • Simple connection of the KTS series to vehicles
  • Clear communication via multiplexer and future cable adapter recognition: K and L line, SAE and CAN can be connected to all possible terminals on the OBD connector
  • Intelligent adapter cable guarantees for the future:
    • Reliable control of the multiplexer
    • Automatic ECU search function
  • OBD-exchange adapter integrated in device, for simple replacement later with an updated version
  • Simple fastening and releasing by means of a module mounting bracket
  • Visual and acoustic status identification/monitoring of the wireless connection
  • Simulation mode can be adjusted individually via the DDC
  • Resistance measurement with enhanced measurement ranges
  • Continuity tester for locating faults
  • Diode measurement for testing in components
  • Voltage measurement with enhanced measurement functions
  • Current measurement with additional adaptation option of FSA current clamps
  • Universal application for passenger cars and commercial vehicles by means of universal OBD connector, for 14 V and 28 V vehicle electrical systems

KTS570/540 wireless: convenient and mobile thanks to wireless Bluetooth data transfer

  • Bluetooth Standard Class 1 with a range of up to 100 m
  • Bluetooth USB adapter from Bosch included in scope of delivery for convenient and simple initial installation
  • Control and activation of the installation by means of the integral DDC (Diagnostics Device Configuration) software
  • Automatic KTS module search
  • Wireless connection test by the integrated transducer
  • Test program for testing the wireless connection

Convincing advantages for the workshop

  • Only one direct connection cable
  • Automatic recognition of the vehicle-specific connection
  • Simple, fast adaptation at the vehicle with no risk of incorrect connections
  • Check of connection and matching connection cable
  • Fewer plug connections
  • Simplified and intelligent multiplexer control

NEW! Simplified adapter concept “Easy Connect”

For reliable recognition of manufacturer-specific diagnostic connections, Bosch now introduces the new simplified adapter concept “Easy Connect”. Now, all that needs to be done for reliable control unit diagnostics is to join the manufacturer-specific adapter cable and the OBD diagnostics cable to make a direct connection.


For a detailed look at the benefits of the oscilloscope, see the KTS Oscilloscope page.
