ISTA/P is BMW's Integrated Service Technical Application for programming in service. It plans and executes applicable control-unit software and coding operations; it is distinct from the diagnostic test-plan application commonly called ISTA/D.
Earlier system
BMW's 2008 documentation shows an ISIS server, an ISSS programming installation and ICOM vehicle interfaces. The versions of the ISSS base installation and ISTA/P data had to be compatible. The same manual identifies ICOM A for the OBD route, B for the applicable MOST route and C for the older 20-pin socket. Its compatibility tables apply to that document's vehicle and software generation.
Choosing a route
Do not assume all BMW platforms are programmed with the same ISTA/P release or that a newer ISTA diagnostic installation replaces every earlier programming function. Check BMW's current regional instructions, supported interface, data and authorisation for the exact vehicle and operation.
Before executing a plan, record the actual vehicle and control-unit state and use the specified external programming power supply and a reliable connection. Review the plan as a whole: a service programming operation can affect multiple control units. See SSS and Progman for the preceding system and ISTA Plus for later service diagnostics.
