The Obd2 Tech 2 scanner stands as a cornerstone diagnostic tool for automotive technicians and serious DIY enthusiasts working with a range of vehicle brands, primarily within the General Motors (GM) family. This robust device offers in-depth diagnostic capabilities for GM vehicles manufactured between 1992 and 2014, and extends its functionality to brands like SAAB, Opel, Suzuki, Isuzu, and Holden with the appropriate software. Known for its reliability and comprehensive access to vehicle systems, the Tech 2 provides functionalities often found in dealership-level tools, making it an invaluable asset for accurate and efficient vehicle servicing.
Key Features and Benefits of the OBD2 Tech 2 Scanner
The Tech 2 scanner distinguishes itself from basic OBD2 scanners by offering advanced diagnostic functions and broader vehicle system coverage. Here are the core advantages that make it a preferred tool for professionals:
1. Extensive Vehicle Coverage and Multi-Language Support: The OBD2 Tech 2 isn’t limited to just one brand. It supports a wide array of manufacturers including GM, SAAB, Opel, Suzuki, Isuzu, and Holden. To cater to a global user base, it offers software in multiple languages including English, Italian, French, Portuguese, German, Spanish, Korean, Japanese, Thai, and Chinese. This multilingual capability ensures accessibility and ease of use for technicians worldwide.
2. Updatable Software for Longevity: Unlike many scan tools that become outdated quickly, the Tech 2 is designed for longevity. Software updates are provided via 32MB Software Cards. As new vehicle models and systems emerge, users can simply acquire new software cards to keep their tool current, protecting their investment and ensuring continued compatibility.
3. Broad Car Model Support and Year Range: The Tech 2 is specifically designed for the brands mentioned above, covering a substantial year range from 1992 up to 2014 for GM vehicles. When combined with TIS2000 software, its capabilities extend to programming functions for vehicles manufactured before 2007, offering both diagnostic and reprogramming functionalities within a single tool. It is important to select the correct software card for the specific vehicle brand you intend to diagnose before use.
4. Professional-Grade Diagnostics: The Tech 2 is the same tool utilized by GM technicians in dealerships. This means it offers authentic GM software and provides comprehensive on-board diagnostics for all vehicle systems from 1992 through 2014. Its capabilities go beyond basic code reading, offering bi-directional control, live data streaming, component testing, and module programming (with TIS2000), mirroring the functionality of a high-end, dealership-level diagnostic system.

Understanding the CAN Interface and OBD II Transition
The automotive industry’s shift from OBD II to Controller Area Network (CAN) protocol is important to consider when using diagnostic tools. Vehicles utilizing the CAN interface require the Tech 2 Flash and a CAN diagnostic interface module (CANdi) to function correctly.
The CANdi module bridges the Tech 2 diagnostic link cable and the OBD adapter. Once connected, it enables the Tech 2 to diagnose all GM vehicle applications, including those using OBD I, OBD II, and CAN protocols.
GM Vehicles Utilizing the CAN Interface (Examples):
- 05 Buick Allure (3.6L)
- 05 Buick LaCrosse (3.6L)
- 05 Cadillac CTS (3.6L)
- 05 Chevrolet Cobalt (2.2L)
- 05 Chevrolet Corvette (6.0L)
- 05 GMC Envoy (5.3L)
- 05 Pontiac GTO (6.0L)
This is just a partial list; many 2005 and newer GM models incorporate the CAN interface. Always verify vehicle specifications to ensure correct diagnostic procedures and equipment are used.

OBD2 Tech 2 vs. GM MDI: Key Differences
When considering professional GM diagnostic tools, the GM MDI (Multiple Diagnostic Interface) is another option. Here’s a comparison to highlight the distinctions between the Tech 2 and MDI:
| Content | For GM Tech 2 | For GM MDI |
|---|---|---|
| Language | GM-English, German, Spanish, Japanese, French, Thai, Portuguese, Korean, SAAB-English, OPEL-English, Italian, German, Spanish, HOLDEN-English, SUZUKI-English, ISUZU-English | Multi-language: English, French, German, Japanese, Italian, and approximately 30 languages in total. |
| Update | Via 32MB Software Card | Cannot update. |
| Activation | No activation required. | Yes, activation is required. |
| Software Handling | Cannot plug in original software card but supports original program functionality. | Supports software directly from the original factory. |
| OS Requirement | No PC connection needed for basic diagnostics. | Requires Windows XP. |
| Internet | No internet connection needed for operation. | Should not be connected to the internet during software installation as it may prompt unwanted updates. |
| Car Model Support | Cars only (no trucks). Supports all GM systems from 1992 up to current year (2014). Brands: GM/SAAB/OPEL/SUZUKI/ISUZU/HOLDEN. | Supports all GM cars from 1990-2019 (and potentially newer depending on updates, though officially stated as 2019). |
| Programming | Supports reprogramming, but requires use with TIS2000 software. | Supports offline programming for brands like Chevrolet and Opel, but not universally for all car models. |
In summary, the Tech 2 is a robust, standalone tool ideal for pre-2014 GM vehicles and offers broad brand support through software cards. The MDI, while offering wider year coverage and potentially more modern features, may have update and software handling limitations.
