Encountering a check engine light can be a stressful moment for any car owner. Your dashboard suddenly illuminates with a warning, leaving you wondering about the potential issue and the cost of repair. Fortunately, diagnosing the problem yourself has become increasingly accessible thanks to OBD (On-Board Diagnostics) scanners. These tools can read the error codes from your car’s computer, providing valuable insights into what might be wrong. But before you rush out to buy one, you might be wondering: where can I borrow an OBD scanner?
This article will guide you through the options for borrowing an OBD scanner, allowing you to troubleshoot your check engine light without immediately investing in diagnostic equipment. We’ll explore free and affordable avenues, ensuring you can get the information you need to make informed decisions about your car’s health.
Understanding OBD Scanners and Why Borrowing Might Be the Right Choice
An OBD scanner, also known as a code reader or scan tool, is a device that plugs into your car’s OBD port, typically located under the dashboard. This port provides access to your vehicle’s computer system, allowing the scanner to retrieve diagnostic trouble codes (DTCs). These codes are generated when the car’s computer detects a problem in various systems, such as the engine, transmission, or emissions control.
For many car owners, a check engine light is an infrequent occurrence. Purchasing an OBD scanner, which can range in price from basic to quite expensive for advanced models, might not be the most economical choice if you only need it occasionally. This is where borrowing an OBD scanner becomes a smart and cost-effective solution. It allows you to quickly diagnose the issue at hand without the upfront cost of buying a tool you may not frequently use.
Top Places to Borrow an OBD Scanner
If you’re looking to borrow an OBD scanner, here are some of the most accessible and convenient places to consider:
1. Auto Parts Stores: Your Go-To for Free OBD Scanner Loans
Many major auto parts retailers, like AutoZone, Advance Auto Parts, and O’Reilly Auto Parts, offer free OBD scanner loan programs. This is often the most readily available and easiest option for most car owners.
How it typically works at Auto Parts Stores:
- Visit a Local Store: Head to your nearest branch of a participating auto parts store.
- Inquire About the Loan Program: Ask an employee about borrowing an OBD scanner or their “code reading service.” While some stores might offer to read the codes for you as a service, explicitly inquire about borrowing the tool yourself if you prefer to do it hands-on.
- Borrow the Scan Tool: The store will usually lend you a basic OBD scanner for free. In some cases, they may require a refundable deposit, which you’ll get back when you return the tool in good working order.
- Use the Scanner in Your Car: Follow the steps provided by the store or the instructions included with the scanner (and outlined in the next section of this article) to connect it to your car’s OBD port and retrieve the diagnostic codes.
- Return the Scanner and Get Assistance: Once you’ve scanned your vehicle, return the tool to the auto parts store. Often, the staff can help you interpret the codes and even provide printouts of the diagnostic report. They can also recommend potential parts you might need to fix the identified issue.

Benefits of borrowing from Auto Parts Stores:
- Free of Charge (or minimal deposit): This is the most significant advantage – it’s a free diagnostic service.
- Expert Advice: Store staff can often assist with code interpretation and suggest repair solutions.
- Convenience: These stores are widely accessible in most areas.
- Parts Availability: If the scan reveals a faulty part, you can conveniently purchase it at the same store.
2. Public Libraries: An Unexpected Resource
While less common than auto parts stores, some public libraries are starting to include OBD scanners in their “library of things” or tool lending programs. This is a growing trend in community resource sharing.
How to check if your local library offers OBD scanner loans:
- Check the Library Website: Visit your local public library’s website and search for “tool lending,” “library of things,” or browse their catalog for “OBD scanner” or “car diagnostic tool.”
- Contact the Library Directly: Call or visit your local library and ask if they have an OBD scanner loan program.
Benefits of borrowing from Public Libraries:
- Free: Library loans are typically free with a library card.
- Community Resource: Supports local community initiatives and resource sharing.
Limitations of borrowing from Public Libraries:
- Availability: Not all libraries offer this service.
- Limited Expertise: Library staff may not be able to provide technical assistance with code interpretation.
- Loan Periods: Loan periods might be limited, requiring timely return.
3. Friends, Neighbors, or Car Enthusiast Communities
Don’t underestimate the power of your personal network! If you know friends, neighbors, or belong to online car enthusiast communities, reaching out to borrow an OBD scanner can be a viable option.
How to leverage your network:
- Ask Friends and Neighbors: Simply ask around if anyone you know owns an OBD scanner and would be willing to lend it to you.
- Online Car Forums and Groups: If you’re part of online car communities, post a request to borrow a scanner in your local area. Fellow car enthusiasts are often willing to help each other out.
Benefits of borrowing from your network:
- Personal Connection: Borrowing from someone you know can be more comfortable and friendly.
- Potential for Assistance: Friends or car enthusiasts might be able to offer advice and guidance.
Limitations of borrowing from your network:
- Availability: Relies on someone you know owning a scanner and being willing to lend it.

Step-by-Step Guide to Using a Borrowed OBD Scanner
Once you’ve borrowed an OBD scanner, here’s a general guide on how to use it to diagnose your check engine light:
-
Preparation:
- Turn Off Your Vehicle: Ensure your car’s engine is completely turned off and the ignition is off.
- Locate the OBD Port (DLC): The Data Link Connector (DLC), or OBD port, is typically located under the dashboard on the driver’s side. It’s often near the steering column or fuse box. Refer to your car’s owner’s manual if you’re unsure of its exact location.
-
Connecting the Scanner:
- Plug in the OBD Scanner: Connect the OBD scanner’s cable to the OBD port. It should only fit in one orientation. Do not force it.
-
Reading the Codes:
- Turn Ignition to “ON” (Engine OFF): Turn your car key to the “ON” position, which powers up the electronics, but do not start the engine.
- Follow Scanner Instructions: The OBD scanner will usually power on automatically. Follow the on-screen prompts. You may need to select “Read Codes” or a similar option depending on the scanner model.
- Wait for the Scan: The scanner will communicate with your car’s computer and retrieve the diagnostic codes. This process usually takes a few seconds. The scanner will typically display “Reading Codes…” or a similar message, followed by “Done” or code results.
- Note Down the Codes: Write down or take a picture of any trouble codes displayed on the scanner’s screen. These codes are usually in a format like “P0123” (a P followed by four numbers).
-
Interpreting the Results:
- Consult the Auto Parts Store (if borrowed from there): If you borrowed the scanner from an auto parts store, return it and ask them to help you interpret the codes.
- Online Resources: You can search online for OBD code definitions using websites like OBD-Codes.com or RepairPal.com. Enter the code you retrieved to get a description of the potential issue.
- Seek Professional Advice: Remember that OBD codes provide a starting point for diagnosis. For complex issues or if you’re unsure how to proceed, consult a qualified mechanic for a professional diagnosis and repair.
Borrowing vs. Buying an OBD Scanner: Making the Right Choice
