At its core, ISTA is a comprehensive platform designed to communicate directly with a vehicle's onboard computers. Unlike generic OBD-II scanners that merely read basic trouble codes, ISTA provides dealer-level access to every electronic control unit (ECU) in the vehicle. It is split into two primary components: ISTA-D (often referred to as ISTA+) for diagnostics, guided troubleshooting, and repair manuals, and ISTA-P for programming and coding.
