Porsche System Tester 2 / KTS-500

The Porsche System Tester was introduced in 1997 for Porsche dealers to service the 986 and 996 model cars, though the Porsche System Tester 2 (PST2) is capable of diagnosing all models since the 928.

The Porsche System Tester 2 is based on the Bosch KTS-500 computer system but uses Porsche specific software that is not available on the KTS-500.

The Porsche System Tester 2 and the KTS-500 are no longer available.

Porsche Integrated Workshop Infomation System (PIWIS) / KTS-650

The PIWIS is the latest Porsche diagnostic tool, and is similar to the Porsche System Tester 2 but also supports CAN-BUS vehicles. PIWIS also integrates repair manual information into the diagnostic tester. The PIWIS is only available on long term lease from Porsche for $12,000 per year.
The PIWIS is based on the Bosch KTS-650, but again it's software is Porsche specific. The Bosch KTS series supports some basic Porsche functions on Porsche 964, 969, and 944.

The PIWIS looks just like the KTS 650 except that it is grey instead of green.
