Bosch identifies early-1990s ESI as Electronic Service Information on CD-ROM for MS-DOS, initially for Bosch Car Service and, for diagnosis, used in conjunction with a KTS 300.
This early product should be distinguished from later Windows ESI[tronic] and the 2012 ESI[tronic] 2.0 generation. Bosch’s separate KTS history dates ESI[tronic] being introduced on its testers to 1999; these dates describe different milestones, not necessarily a contradiction.
