The Tech 2 is a handheld General Motors diagnostic tool also used for selected Opel, Vauxhall, Saab and Suzuki vehicles. The hardware is shared, but vehicle coverage depends on the correct market- and brand-specific software, vehicle interface, adapters and model. Consult the manufacturer's application information before choosing equipment. GM Tech2 user guide, archived copy; Saab TIS 2000 technical description; Opel/Vauxhall diagnostic application matrix.
What it does
Tech 2 communicates with vehicle control modules to support fault diagnosis, data display and specified service functions. On Saab systems, TIS 2000 provides PC-based services including diagnostic snapshot display, Tech 2 software downloads and Service Programming System (SPS) reprogramming; the Tech 2 communicates with the vehicle. See the Saab technical description and 2010 Saab 9-3 programming procedure.
Hardware and software
The GM user guide documents the PCMCIA card and CANdi interface. GM also offers Tech2Win, a PC application that emulates the Tech 2; it needs a supported vehicle interface and the appropriate licensed software. It should not be assumed to cover every vehicle or function available to a physical Tech 2. See the GM guide, archived copy and ACDelco Technical Delivery System.
Suzuki applications
A Suzuki Motor USA service bulletin specifically documents Tech 2 diagnostic software and Techline Connect for the 2007–2009 XL7. This is a particular North American application, not an assertion that all Suzuki models or GM software cards are interchangeable. See Suzuki diagnostic systems. Suzuki Motor USA bulletin SI-32.
Related systems
See GM GDS2 and Techline Connect for later PC-based diagnostics and programming workflows, Opel diagnostic systems for the Opel/Vauxhall selection, and Saab diagnostic systems for Saab-specific applications. Platform changes overlap between models: do not choose equipment by year alone.
Holden and Isuzu applications
Holden documented Tech 2 for its vehicles and a separate Isuzu General Export application for the RA Rodeo, loaded through TIS 2000. See Holden diagnostics and Isuzu diagnostics. Holden service Techline TL0663-0402. Earlier shared applications are discussed in GM Tech 1.
