Introduction
The Porsche 928 is a complex piece of machinery with advanced electronics, developed in the early 70’s and first released in 1978.
In 1986, Porsche started using advanced Bosch Automotive Electronics, and in 1987, the first controllers with internal diagnostics and fault memory were fitted.
Diagnostic System
The 928 Diagnostic Software connects to the diagnostic port and communicates with various controllers, including LH injection, EZK ignition, RDK tire pressure, ABS, PSD, Alarm, and Airbag controllers.
The software is intended for both personal use and workshops, and is compatible with 928 controllers from 1987 onwards.
