A check engine light can be a source of anxiety for any driver. What does it mean? Is it a serious problem? Understanding the issue often requires reading the OBD2 code. This is where a reliable OBD2 scanner like the Craftsman Obd2 47156 comes in handy. This article will discuss the importance of OBD2 scanners, highlight the features of the Craftsman OBD2 47156 (although the model number mentioned might be incorrect as Craftsman uses 5 digit model numbers for their OBD2 scanners, and we’ll refer to general Craftsman OBD2 features), and guide you on how to choose the right one for your needs.
Understanding OBD2 and Its Importance
OBD stands for On-Board Diagnostics. OBD2, implemented in 1996 for all US vehicles, is a standardized system that allows you to access diagnostic trouble codes (DTCs) stored in your car’s computer. These codes pinpoint potential issues, ranging from minor sensor malfunctions to significant engine problems.
Having an OBD2 scanner enables you to:
- Diagnose Check Engine Light: Identify the root cause of the illuminated warning light.
- Save Money on Diagnostics: Avoid diagnostic fees charged by repair shops.
- Empower DIY Repairs: Determine if the issue is something you can fix yourself.
- Negotiate Repair Costs: Understand the problem beforehand when dealing with mechanics.
- Monitor Vehicle Health: Track and address potential issues before they become major.

- Easy-to-Use Interface: Simple navigation and clear display for user convenience.
Choosing the Right OBD2 Scanner
While a basic OBD2 scanner like the Craftsman model suffices for most car owners, more advanced features might be beneficial for others:
