Bosch Diagnostics / Bosch KTS diagnostic testers

The KTS 550 is the higher-measurement companion to the KTS 520. Bosch documents ECU diagnosis, a two-channel multimeter and a two-channel oscilloscope, with RS-232 and USB PC connections.

Hickleys lists update cut-offs for some legacy testers; its published dates are distributor information, not a guarantee of present worldwide support. Verify the exact software release and subscription before purchase.
