Bosch Diagnostics / Bosch KTS diagnostic testers
The KTS 540 provides ECU diagnosis and one-channel multimeter measurements. Bosch documents both USB and Bluetooth host links; unlike the 570 it does not include the latter’s two-channel oscilloscope.
Confirm the exact device, software version, adapters and supported vehicle functions before relying on a particular feature.
