FAQs
What is the best OBD2 scanner that does everything?
There is no single OBD2 scanner that truly “does everything” for all vehicles at a dealership level. However, high-end professional tools like Autel MaxiSys series and Snap-on scan tools come closest.
These scanners offer full system diagnostics, bi-directional control, coding, and programming functions across many vehicle brands, including GM, Ford, Toyota, and others. Even then, some factory-level programming may still require OEM software.
What scan tool is used for GM vehicles?
The most well-known factory scan tool for GM vehicles is the GM Tech 2. It was widely used at dealerships for Chevrolet, GMC, Buick, Cadillac, and other GM brands, especially for models through the early 2010s. Modern GM vehicles now use GM MDI and GDS2 software systems, which are computer-based diagnostic platforms used by dealerships.
What scanner do most mechanics use?
Most independent mechanics use professional aftermarket scan tools such as Autel, Launch, Topdon, or Snap-on scanners. These tools are popular because they support multiple car brands, offer full system diagnostics, and include advanced functions like ABS bleeding, injector coding, and sensor calibration. For GM-specific work, many mechanics still keep Tech 2 or modern GM-compatible scanners as secondary tools.
What is the best OBD2 scanner for a Chevy Silverado?
For a Chevy Silverado, the best OBD2 scanner depends on your needs. For advanced diagnostics and bi-directional control, tools like FOXWELL NT510 Elite or CGSULIT SC530 are strong choices.
For basic use like reading and clearing engine codes, a simpler scanner like Innova 5210 is sufficient. If you want dealership-level capability, GM MDI systems are the closest to factory-grade diagnostics.
Where can I buy a GM Tech 2 scanner?
GM Tech 2 scanners are no longer sold new by General Motors. However, they can still be found through online marketplaces, automotive diagnostic tool retailers, and second-hand listings. Many available units are refurbished or clone versions. While still useful for older GM vehicles, newer Chevrolet models require GM MDI or GDS2-based systems for full compatibility.
Final Verdict
The FOXWELL NT510 Elite stands out as the best overall OBD2 scanner for Chevy owners due to its professional-level diagnostics, advanced service functions, and bi-directional controls.
The CGSULIT SC530 is an excellent option for Chevrolet owners who want extensive GM-specific coverage and advanced maintenance features at a competitive price.
For budget-conscious users, the Innova 5210 offers dependable performance and essential diagnostic functions while remaining easy to use.
No matter which scanner you choose, investing in a quality OBD2 tool can help you diagnose problems quickly, reduce repair costs, and keep your Chevrolet vehicle running smoothly for years to come.
