Key Features to Consider in an OBD2 Scanner for GM

Once you have a clear understanding of your needs, consider these essential features when choosing the best OBD2 scanner for your GM:

1. Vehicle Coverage

Ensure the scanner explicitly states compatibility with GM vehicles, including the specific make, model, and year of your car. Look for scanners that support GM-specific protocols like SAE J1850 VPW and PWM, commonly found in older models.
