That dreaded check engine light – it’s a signal every car owner fears. Recently, my sister experienced this familiar automotive distress call. Her first question, like many others, was: “What does it mean?” Modern vehicles are equipped with on-board diagnostic systems, specifically OBD2, to communicate these very issues. When something isn’t quite right, your car alerts you, and crucially, it provides specific diagnostic codes to pinpoint the problem.
OBD, or On-Board Diagnostics, is a standardized system. OBD2 has been mandatory in all cars sold in the USA since 1996, and similar standards exist worldwide. Instead of immediately heading to an expensive mechanic, there are accessible first steps you can take.
I advised my sister to visit Advance Auto Parts, a place known for offering free OBD scans. They’ll not only read the code but also provide a printout and explain its basic meaning. Many auto repair shops charge a diagnostic fee just for this simple OBD II scan, the very service offered freely at parts stores.
But here’s a better option: you can easily read these OBD codes yourself. All it takes is an affordable scan tool. The Craftsman OBD2 car code reader, model 3030SC, is a prime example, available for around $70. Craftsman has released several new code readers, but this entry-level model stands out for its affordability and user-friendly design. It’s a practical tool for any car owner wanting to understand their vehicle better.
The Craftsman 47156 OBD2 reader plugs into your car’s OBD II port, typically located under the steering column on the driver’s side. It quickly retrieves trouble codes and provides a general description of the issue directly on its screen. This initial information empowers you to conduct further research online. You might find the problem is a simple fix you can handle yourself, or you’ll gain valuable insight before consulting a mechanic.
While you have the option to clear trouble codes with the Craftsman 47156, remember that clearing a code doesn’t fix the underlying problem. If you’re hoping to pass an inspection, the light will reappear until the issue is properly resolved.
Beyond basic code reading, the Craftsman Obd2 Abs 47156 model includes ABS (anti-lock brake system) code diagnostics. This is a significant feature in a tool at this price point. Furthermore, as indicated on the product packaging, it incorporates a Freeze Frame feature. Freeze Frame captures data at the moment a trouble code is triggered, providing a snapshot of crucial parameters that can aid in diagnosis.
More advanced scan tools often offer even more features and broader compatibility, including reading codes from older vehicles. However, for most car owners, a reader that can accurately read, explain, and clear codes is sufficient. The Craftsman 47156 hits this sweet spot, offering essential functionality at a reasonable $70 price, a considerable improvement over older, basic models that only displayed cryptic code numbers.
For budget-conscious buyers, Amazon offers numerous scan readers starting under $20. However, for reliable performance and essential features like on-screen definitions, stepping up to the Craftsman 47156 is a worthwhile investment. While models like the Actron CP9125 PocketScan (around $50 on Amazon) exist, they lack on-screen definitions, making the diagnostic process less user-friendly. The Actron CP9550 PocketScan Plus, priced closer to the Craftsman, doesn’t offer a compelling advantage over the Craftsman 47156, especially considering the Craftsman’s inclusion of ABS diagnostics and Freeze Frame.

Investing in an OBD II scan tool like the Craftsman 47156 is a smart move. It can easily pay for itself after just one or two uses, saving you diagnostic fees and empowering you to take control of your car’s maintenance.
