Bosch Diagnostics
ESI began as Electronic Service Information and evolved from service data into a combined diagnostic and workshop-information product. It is software; a compatible KTS interface, appropriate licence and sometimes manufacturer authorisation are also needed for vehicle functions.
Bosch dates DOS-based ESI on CD to the early 1990s, Windows ESI to the mid-1990s, ESI[tronic] 2.0 to 2012 and the Online name to 2018. In 2024 Bosch said ESI[tronic] 2.0 Online became ESI[tronic], rather than remaining a separately named current product.
