Note: As of my latest knowledge update and product lifecycle reviews, the Bosch KTS 570 is a legacy/discontinued module. It has been succeeded by the KTS 590 and the newer KTS 5xx series (like KTS 560, 590, 690). However, it remains widely used in the used diagnostic equipment market. 1. Introduction and Product Positioning The Bosch KTS 570 is a professional, modular vehicle diagnostic interface. It belongs to the Bosch KTS 500 series (which includes the KTS 540, KTS 570, and KTS 590). Designed for independent workshops and professional technicians, the KTS 570 served as a mid-to-high-range solution for comprehensive vehicle diagnostics, bridging the gap between the entry-level KTS 540 and the top-tier KTS 590.
