7 Best GM Scan Tools Review 2021 [Update]


Like many motorists in these difficult times, there is a fair chance that you are searching for ways to cut costs. DIY mechanics enjoy a renaissance thanks to technology improvements, including a vast array of OBD2 Scanners for all enthusiasts.

With almost 3 million new General Motors vehicles sold annually, there is a competitive market for GM specific scanning and diagnostic tools. These cover all Chevrolet, Buick, GMC, and Cadillac models.

Complete beginners, DIY mechanics, hobbyists, technicians, and pro mechanics all have different requirements. GM OBD2 scanners suit every level, and they are generally a compromise between cost and functionality. The trick is only to buy what you need at the best quality for your price range.

These days, almost anyone can save themselves an expensive and inconvenient trip to the mechanic and improve their fuel consumption. Whatever your level of expertise, I will take you on my journey by identifying the best GM scanner for each situation and giving you the benefit of my buying experience.

Buying Guide
Why Do I Need a GM Scanner?

Most GM owners want a combination of the most common OBD2 diagnostic functions. After connecting easily via Bluetooth, WiFi, or an ethernet cable, your device should automatically identify a problem once the check engine light comes on and clear the associated fault.

This tool is a real cost-saver compared to the expense and hassle of trusting your car to a repair shop. Apart from the satisfaction of fixing your vehicle, OBD2 scanning technology puts you back in control.

Most users require essential functions for testing their vehicle’s emissions before it fails a costly smog test. Hobbyists want options for fine-tuning ignition timing, fuel consumption, and overall efficiency. Diagnostics experts and pro mechanics demand a full range of functions, including access to safety systems and advanced real-time diagnostics.

To know which type of buyer you are, ask yourself what functions you require and how much your budget is. It’s best not to pay for a top of the range, pro-GM scan tool if you never use most options. You can always upgrade once your knowledge becomes more advanced.
