Why a Dedicated GM Scan Tool?
While generic OBD-II scanners can read basic diagnostic trouble codes (DTCs), they often fall short when dealing with GM-specific systems. A dedicated GM scan tool offers deeper access to modules like the body control module, powertrain control module, and transmission control module, allowing for more precise diagnostics and bi-directional control. This can be crucial for tasks like diagnosing ABS issues, programming new key fobs, or performing advanced powertrain diagnostics.
What to Consider When Choosing a Best GM Scan Tool
Selecting the right scan tool involves several key factors. First, consider your budget. Prices range from under $100 for basic code readers to thousands for professional-grade tools. Next, think about your skill level. Some tools are designed for DIYers, while others require a deeper understanding of automotive systems. Finally, consider the specific GM vehicles you’ll be working on. Some tools specialize in certain models or years.
