Early BMW ISTA was a workshop system made from several cooperating parts. The names describe different roles, so an ISIS server, an ISID display and an ICOM are not interchangeable.

Components

  • ISIS — Integrated Service Information Server: the workshop server, connected to BMW and hosting server-specific ISTA components.
  • ISID — Integrated Service Information Display: the mobile workshop tester with an ISTA client. BMW describes online operation and a temporary offline mode.
  • ISSS — Integrated Software Service Station: a programming system in the early ISTA/P architecture. Its installed base and data had to match.
  • ICOM: the vehicle communication interface. IMIB is a separate measurement device; ISAP is a workshop wireless access point.

Example flow

A technician uses the ISID client, selects an ICOM connected to a vehicle, and runs a supported diagnostic test while the workshop system supplies the relevant data. BMW's early ISTA/P documentation illustrates a separate ISSS/ISIS software arrangement. Dealer infrastructure evolved, so this historical configuration should not be imposed on every present-day ISTA installation.

For illustrated server and interface diagrams see the BMW ISTA/P manual. Continue to early ISTA/D and ICOM.
