Can You Rent An Obd2 Scanner?
If your car’s check engine light turns on, you may feel worried. The mechanic can help, but that often costs money just to find out what’s wrong. The good news is, you don’t always need to buy a tool to check your car yourself. Many people wonder: Can you rent an OBD2 scanner instead of buying one?
This article will guide you through the facts about renting OBD2 scanners. You’ll learn how renting works, where to rent, the cost, what to expect, and how to avoid common mistakes. If you’re new to car diagnostics, you’ll also find practical tips and clear explanations.
By the end, you’ll know if renting an OBD2 scanner is right for you.
What Is An Obd2 Scanner?
An OBD2 scanner is a device that connects to your car and reads its computer data. OBD stands for “On-Board Diagnostics.” The “2” means it’s the second version, used in most cars made after 1996 in the US. These scanners help you:
- Check trouble codes when the check engine light comes on
- Read live data from sensors
- Reset warning lights after fixing problems
There are two main types:
- Basic OBD2 scanners: Show simple codes and let you clear them.
- Advanced OBD2 scanners: Offer more detailed info, can read ABS, airbag, and other systems.
Some scanners connect with Bluetooth to your phone, others are handheld devices with their own screen.
Why Rent Instead Of Buy?
Buying your own OBD2 scanner can be a good idea if you work on your car often. But for most people, renting makes sense for several reasons:
- Cost savings: Renting is much cheaper if you only need the scanner once or twice.
- No storage hassle: You return it after use, so it doesn’t take up space at home.
- Try before buying: Renting lets you test different models before deciding to buy.
- Special features: You can rent advanced scanners for tough jobs without paying full price.
You should consider renting if your car is not showing issues often or if you just want a quick diagnosis.
Where Can You Rent An Obd2 Scanner?
Several places offer OBD2 scanner rentals. Here’s where you can look:
- Auto parts stores: Many big chains in the US offer a “loaner tool program.” You pay a deposit, use the tool, then get your money back when you return it.
- Online rental services: Some websites let you rent scanners and ship them to your door. Shipping may add to the cost.
- Local mechanics and garages: Some shops loan scanners for a small fee, especially if you’re a regular customer.
- Peer-to-peer rental apps: These apps connect owners with people who want to rent tools.
Here’s a simple comparison of three common options:
| Rental Source | Deposit Needed | Typical Cost | Availability |
|---|---|---|---|
| Auto parts store | Yes | $0-$40 (refundable) | Immediate, local |
| Online rental | No or Yes | $20-$50 + shipping | 1-3 days for delivery |
| Mechanic/garage | No | $10-$25 | Local, sometimes limited |
Most people use auto parts stores because it’s fast and easy.
How Does The Rental Process Work?
Renting an OBD2 scanner is simple. Here’s how it usually goes:
- Visit the store or website: Ask for an OBD2 scanner rental.
- Pay a deposit: At stores, you pay a deposit equal to the price of the tool. This is fully refunded when you return the scanner.
- Get the scanner: The store gives you the scanner and instructions. Online rentals ship it to your address.
- Use the scanner: Plug it into your car’s OBD2 port (usually under the dashboard). Read the codes.
- Return the scanner: Bring it back within the rental period (often 24–48 hours). Your deposit is refunded.
Some stores may require ID or a loyalty card. Always check the store’s rental rules.

What Does It Cost To Rent An Obd2 Scanner?
Costs can vary, but here’s what you can expect:
- Auto parts stores: Usually $0 to $40 deposit, refunded. Sometimes a small fee if you keep it longer.
- Online rentals: $20-$50 for a week, plus shipping ($5-$10).
- Mechanic shops: $10-$25 for a quick use.
If you rent often, buying a basic scanner ($25-$80) may be cheaper in the long run.
Here’s a comparison of buying vs. renting:
| Option | Upfront Cost | Long-term Cost | Extra Fees |
|---|---|---|---|
| Renting | $0-$50 | Low for one-time use | Late fees, shipping |
| Buying | $25-$200 | Better for frequent use | None |
What To Look For When Renting
Not all OBD2 scanners are the same. Before renting, check these factors:
- Compatibility: Make sure the scanner works with your car’s year, make, and model.
- Features: Do you only want to read codes, or do you need advanced info like ABS or airbag diagnostics?
- Ease of use: Some scanners are simple, others have complex menus.
- Condition: Check the scanner for damage or missing cables before leaving the store.
- Rental period: Ask how long you can keep the scanner.
If you need to diagnose a problem beyond the check engine light, ask for a scanner with extra features.
How To Use A Rented Obd2 Scanner
Using an OBD2 scanner is easy, even for beginners. Here’s a step-by-step guide:
- Locate the OBD2 port: It’s usually under the dashboard, near the driver’s seat.
- Plug in the scanner: Insert the connector firmly.
- Turn on ignition: The car should be in “on” position, but not running.
- Follow scanner instructions: Some scanners have buttons, others use a phone app.
- Read the codes: The scanner shows codes like P0300 or P0171. Write them down.
- Look up the codes: Use the scanner’s manual or search online for code meanings.
- Clear codes (optional): If you fix the problem, you can clear the codes.
Here’s an example of a common code:
- P0420: This means “Catalyst System Efficiency Below Threshold.” It usually relates to the catalytic converter.
Common Mistakes When Renting
Renting can save money, but watch out for these mistakes:
- Not checking compatibility: Some scanners don’t work with certain cars, especially older or foreign models.
- Returning late: Stores may charge late fees if you miss the deadline.
- Ignoring instructions: Not following usage steps can damage the scanner or your car.
- Misreading codes: Codes can mean different things for different cars. Double-check before buying parts.
- Clearing codes without fixing: Erasing codes does not fix the problem. It may hide issues from mechanics.
One non-obvious insight: Some scanners only read basic codes. If your car has a special warning (like ABS or airbag), ask for a scanner that covers those systems.
Real-life Example: Renting From An Auto Parts Store
Let’s say your check engine light turns on, and you go to AutoZone (a popular US chain). Here’s what happens:
- You ask for a scanner at the counter.
- The staff takes your ID and asks for a deposit (usually the price of the tool).
- You get a scanner and simple instructions.
- After diagnosing your car, you return the scanner and get your deposit back.
Some stores even let you use the scanner in the parking lot for free. This can save time and help you decide if you need professional repair.

Extra Tips For Beginners
- Ask for help: Staff at auto parts stores can show you how to use the scanner.
- Check the manual: Always read instructions before plugging in the scanner.
- Write down codes: Don’t rely on memory. Write or take a photo of the codes.
- Compare code meanings: Use trusted sources for code explanations. Some codes are generic, others are manufacturer-specific.
- Don’t clear codes until fixed: Only erase codes after repairs, or you may hide problems.
Another non-obvious insight: If your check engine light comes back after clearing codes, the problem is still there. Don’t ignore repeated warnings.
Is Renting Right For You?
Renting an OBD2 scanner is best for people who:
- Have a car with a sudden warning light
- Don’t plan to diagnose cars often
- Want to save money on simple checks
- Need a scanner for a short time
If you fix your car often or have multiple vehicles, buying may be smarter. But for most drivers, renting is a quick, low-cost solution.
