Integrated Oscilloscope
The Bosch KTS 590 includes a built-in 2-channel oscilloscope for real-time viewing of electrical signal variation. This enables precise testing of complex electrical circuits including sensor outputs, actuator drive signals, and communication bus waveforms directly through the diagnostic interface, without needing a separate oscilloscope.
ESI[tronic] Diagnostic Software
The Bosch KTS 590 works with ESI[tronic] software to provide a complete professional diagnostic solution. ESI[tronic] delivers reading and deleting fault codes, live data display with graphical analysis, actuator testing, service interval resets, sensor calibration, and component learning.
Experience-Based Repair (EBR) provides solutions from over 1 million diagnostic cases worldwide. Manufacturer repair instructions, wiring diagrams, and maintenance schedules are available depending on your ESI[tronic] subscription level.
Secure Diagnostic Access (SDA)
Secure Diagnostic Access provides immediate, full access to protected vehicle electronics via one-time Single Key ID registration, eliminating separate manufacturer accounts.
What’s the Difference: KTS 590 vs KTS 560?
The KTS 590 includes a 2-channel oscilloscope and 2-channel multimeter for advanced electrical testing. The KTS 560 has a 1-channel multimeter only. Both use the same ESI[tronic] software with identical diagnostic coverage. Choose the KTS 590 if you need integrated oscilloscope capability for electrical signal analysis.
Frequently Asked Questions
Why choose the KTS 590 over the KTS 560?
The KTS 590 includes a built-in 2-channel oscilloscope for real-time electrical signal analysis, plus a 2-channel multimeter. The KTS 560 has a 1-channel multimeter only. If you need to view sensor waveforms, actuator drive signals, or communication bus signals, the 590 provides this integrated capability without needing a separate oscilloscope.

Do I need an ESI[tronic] subscription?
Yes. The KTS 590 requires ESI[tronic] software for vehicle diagnostics. ESI provides diagnostic functions, vehicle data, wiring diagrams, and Experience-Based Repair solutions from over 1 million cases worldwide.
How many vehicles does it cover?
Over 130,000 vehicles across 150+ manufacturers, expanded quarterly. See the full coverage list at Bosch.
Is training available?
Yes. We offer a Bosch KTS training course and a 1-day refresher for existing users. Both courses cover KTS 560 and KTS 590 operation with ESI[tronic] software.
Should I buy the tool only or the master pack?
The KTS 590 master pack includes the diagnostic tool with a complete accessory and adapter set. It is better value than purchasing accessories separately.
