Understanding Your GM’s Needs: Why an OBD2 Scanner is Essential
Modern GM vehicles are technological marvels, but even the most reliable car can throw a curveball with an illuminated check engine light. An OBD2 scanner becomes your co-pilot, translating those cryptic codes into understandable diagnoses. Whether you’re a DIY enthusiast or a seasoned mechanic, the right scanner empowers you to:

- View Live Data Stream: Monitor real-time sensor data like engine RPM, coolant temperature, and oxygen sensor readings, providing valuable insights into your vehicle’s performance.
- Perform Advanced Functions (Model Dependent): Some scanners unlock advanced functionalities, such as ABS bleeding, transmission resets, and key programming, for the more experienced user.
