ISTA-D, once properly installed, provides the technician with the ability to do full diagnostic functions; read codes/clear codes, display all data PIDs, activate bi-directional functions and perform BMW's 'Automated Tests'. Additionally, this OEM system provides real time on-line access to the full BMW Service Information (SI) database. SI database information includes such items as BMW's Code Descriptions (Both SAE and BMW specific), Repair Procedures, Wiring Diagrams, Pin Assignments, Connector Views and Installation locations.

The ISTA-P software module provides the technician with the ability to program or re-flash all modules. Whether the technician is replacing a defective module or simply wishing to update an existing working module, ISTA-P enables this to be performed. As an added note, BMW TSB's are also integrated into this OEM scan tool package.
