5. Jethax OBD2 Scanner
Small and light, this OBD 2 scanner makes it easy to connect
Specifications
Display/size: 1 LED
Bluetooth/handheld: Yes/No
I/M Readiness test: No
Displays live data: Yes
Number of keys: N/A
Warranty: 1 year
Size: 1.8 x 1.7 x 0.8 inches
Weight: 0.7 ounces
Reasons to buy
+Built-in flashlight+Easy to insert and remove from OBD port+Good Bluetooth range
Reasons to avoid
–No status LEDs
One of the easiest OBD2 scanners to install, us e and remove, Jethax’s OBD2 Scanner stands alone with a built-in LED flashlight to illuminate the car’s diagnostic port. Its ribbed sides make it a snap to pull out.
The 1.8 x 1.7 x 0.8-inch unit is slightly bigger than Autel’s MaxiAP AP200 but at only 0.7-ounces, it’s significantly lighter. It has a single LED but it was always red.
The Jethax scanner uses Bluetooth 4.0 to connect to an iPhone, iPad or Android phone but lacks its own app. The QR code on the unit’s box points to several free diagnostic apps, including Torque Lite, which I used with my Samsung Galaxy S9 Plus phone.
After plugging the Jethax OBD2 Scanner into my Audi AllRoad’s OBD port and connecting the scanner to my phone, the app started showing live data. In addition to a series of automotive gauges and fault codes, the system can run acceleration tests.
The Jethax has a 28-foot Bluetooth range, which was on a par with other Bluetooth scanners. It found my introduced fault and turned off the check engine light.
Don’t let its size or $35 price tag fool you. Jethax’s OBD2 Scanner not only tells what’s going on inside your car but lights the way to plug it in.

6. Topdon ArtiLink 500
With many manufacturer codes, the Topdon ArtiLink 500 is versatile but lacks repair information
Specifications
Display/size: Color/2.8 inches
Bluetooth/handheld: No/Yes
I/M Readiness test: Yes
Displays live data: Yes
Number of keys: 8
Warranty: 1 year
Size: 6.6 x 3.7 x 1.1 inches
Weight: 10.2 ou nces
Reasons to buy
+Big screen+Includes manufacturer specific codes+OBD plug light
Reasons to avoid
–Big and heavy
With many of the abilities of a professional OBD scanner, Topdon’s ArtiLink 500 does a lot for its $59 price tag.
B ig and bulky, the ArtiLink 500 weighs 10.2 ounces and its 54-inch cable has a lighted connector at the end that helps with plugging the scanner in. The scanner can be updated using its included USB cable.
The ArtiLink 500’s bright 2.8-inch color screen shows fault codes, a pre-inspection readiness report and definitions of what its fault codes mean. The 8-key interface is efficient and lets you pick from the major categories. This OBD2 scanner shows live car data, can graph it and lets you print it.
ArtiLink 500’s OBD database has many of the manufacturer specific codes that widens its scope compared to those that only use only generic codes. After I introduced a problem with my 2014 Audi AllRoad, the scanner showed the fault and zeroed in on the problem. I was able to turn off the check engine light but the scanner stopped short of providing repair advice that the CarScan Pro 5210 does.
At $59, the Topdon ArtiLink 500 provides many of the abilities of a scanner costing much more but is on the big and heavy side.

7. ThinkDriver Bluetooth OBD2 Scanner
Easy to plug in or remove, the ThinkDriver Bluetooth OBD2 Scanner puts an emphasis on maintenance
Specifications
Display/size: 1 LED
Bluetooth/handheld: Yes/No
I/M Readiness test: Yes
Displays live data: Yes
Number of keys: N/A
Warranty: 1 year
Size: 2.1 x 1.8 x 0.9 inches
Weight: 1.3 ounces
Reasons to buy
+Soft grips on sides+Maintenance functions+Excellent software
Reasons to avoid
–App cost–Need to activate
Easy to use, the ThinkDriver Bluetooth OBD2 Scanner ironically is a slow starter. It not only requires an account, an email verification and hardware activation but you’ll need to update the app and firmware. The first time you use it, figure on spending 20 minutes before you get any automotive data.
It’s worth the wait because the ThinkDriver app is more thorough than its competitors. Its dark interface shows all the data needed, including fault codes, live car data, a pre-inspection I/M readiness test and a comprehensive Health Report. It’s one of the rare apps that can reset the maintenance light on your car for things like changing the oil or replacing the EGR valve.
The ThinkDriver Bluetooth OBD2 Scanner’s soft grips make it easy to install and remove and it connected quickly with my iPad Pro and had a 30-foot range; there’s also an Android app. It quickly found my introduced fault and allowed me to turn off the Check Engine light.
Unlike those that supply free software, the ThinkDriver app expires after a year and costs $15 a year for one car after that. Still, at $70, the ThinkDriver Bluetooth OBD2 Scanner is worth it for those who prefer to change their own oil.
Its large color screen, range of tasks, lifetime warranty and ease of use make the SeekOne SK860 a winner and one of the best OBD2 scanners around.
The price for this is a handheld scanner that at 7.8 x 3.8 x 1.2 inches and 11.2 ounces can feel bulky and heavy. Its soft rubber bumpers and rugged design mean you don’t have to baby the SK860, and it comes with a 58-inch cord and bright, 2.8-inch color display.
Its eight-button navigation scheme and icon-based interface are easier to use than budget scanners. The SK850 has a one-button I/M preinspection readiness key along with a green (no-fault codes), yellow (intermittent problems) and red (permanent-problem codes) LED scheme.
It examined the battery and showed live data, like engine speed, oxygen sensor readings and coolant temperature, then found my introduced fault and turned off the check engine light.
The SK860 does much more than typical handheld scanners and comes with a padded case, but its lifetime warranty makes it stand out from the crowd.

9. Launch CR529 OBD2 Scanner
This OBD2 scanner delivers pro-level features for an affordable price
Specifications
Display/size: Color/2.8 inches
Bluetooth/handheld: No/Yes
I/M Readiness test: Yes
Displays live data: Yes
Number of keys: 8
Warranty: 2 year
Size: 6.5 x 3.8 x 1.2 inches
Weight: 10.5 ounces
Reasons to buy
+Rugged design+2-year warranty+Lifetime updates
Reasons to avoid
–Big and heavy–Slow to respond
With a rugged design, easy-to-use interf ace and lifetime software updates, Launch’s CR529 comes close to being a professional OBD scanner at a bargain price. On the downside, at 10.5 ounces and 6.5 x 3.8 x 1.2-inches, it’s bigger and heavier than Innova’s CarScan Pro 5210 and can be a lot to hold during repairs.
Solidly built, the CR529’s ribbed case can protect it if dropped. Its 2.8-inch color screen shows everything from engine misfires and oxygen sensor status to live automotive data and fault codes. Anything can be printed via its USB port but the CR529’s explanations of the problems it finds pale compared to the in-depth repair details of Innova’s 5210.
The scanner’s eight-key format has a dedicated pre-inspection readiness test key, and the scanner’s LEDs light up red for a permanent fault, yellow for an intermittent fault and green for a clean sweep.
The Launch’s CR529’s 43-inch cable quickly connected to my Audi AllRoad, picked up my added fault and let me turn off the check engine light. Unfortunately, it took upwards of 15 seconds for the scanner to respond at times.
The CR-529’s 2-year warranty is combined with lifetime software updates. At less than $50, it’s priced like a DIY unit but has the abilities of a professional scanner.
The Nexpeak NX501 may be big and heavy, but it goes beyond the expected car checks with a long 5-foot OBD cable and lifetime software updates.
With soft rubber bumpers, the NX501 is ruggedly built and comfortable to use. Its three LEDs for the I/M preinspection test show green for no faults, yellow for a temporary problem or red to show a permanent fault.
In addition to examinations of the battery and oxygen sensor, the NX501 interprets generic and many manufacturer-specific fault codes. The device quickly noticed the introduced fault on my car and turned off the car’s check engine light.
At 2.8 inches, the NX501’s display is bright with colorful icons for different features, and it can show everything from engine speed to coolant temperature along with colorful fever graphs. The tool’s eight-key navigation makes it easy to move between scanning tasks. With its padded case, lifetime software upgrades and one of the longest OBD cables, the NX501 is one of the best OBD2 scanners for the money.
How to choose the best OBD scanner for you
If you’re looking for insights into how your vehicle is working or what’s wrong under the hood, there’s no better way than to plug in one of the best OBD2 scanners and read the results.
After all, it’s how your car dealer or repair shop would figure out what’s wrong with your car when you drive (or are towed) in. Why shouldn’t you have the same information?
The best OBD scanners provide the right mix of size, weight and the ability to read your car’s fault codes and live data. The most important criteria are:
Easy setup. If it takes forever to set up the scanner, you probably won’t use it to diagnose a problem early.
Faults and explanations. The best OBD2 scanners not only tell you the faults your car has but also can explain the meaning so you can either fix it yourself or tell a mechanic.
I/M Readiness check. A good scanner will run the major engine and emissions tests to see if you’ll pass your state’s inspection.
Accuracy. A scanner is worthless if its results aren’t accurate, because the only thing worse than no information is incorrect information.
Size and weight. If the scanner is heavy and bulky, chances are it’ll stay in your toolbox and not in the car to help you on the road.
Live data. By tapping into the car’s engine speed, timing and other parameters, the right scanner can h elp track down an intermittent problem.
Graphs. Numbers are good, but a visual representation of it is much better, particularly if you’re comparing before and after.
Warranty. You expect your car to last at least eight or 10 years, so why shouldn’t your OBD2 scanner? That said, the best offer a lifetime warranty that should outlast your ride.
There’s a gas tank full of criteria used to determine which OBD scanner is the best one for you. The most important is whether you want one that connects with your phone or tablet’s screen over Bluetooth or a handheld unit with its own display and cable.
Next, think about longevity and get one that includes lifetime warranty or software updates so the scanner will stay current with changing automotive tech.
Then, how about screen size for a handheld scanner? Get the biggest, brightest and easiest display to read that is icon based for easy changes. If you’re clumsy, look at rugged scanners with rubber bumpers to absorb the shock of being dropped.
Look for extras that are included on some models, like an electrical multimeter, the ability to read a manufacturer’s proprietary codes or export documents as Acrobat PDF files.
Finally, the price for these sophisticated devices is right on par with professional-level scanners that are available for under $100. That’s barely an hour’s labor for a qualified mechanic, making it a win-win purchase.
How we test OBD2 scanners
To test the best OBD2 scanners, I used my 2014 Audi Allroad vehicle while it was in the garage or on the road over a period of several weeks. After connecting each scanner to my car’s OBD2 port, I made sure they could report the car’s VIN code.
For the wireless scanners, I connected to my Apple iPad Pro, Microsoft Surface or Samsung Galaxy S9+ phone via a Bluetooth or Wi-Fi connection. The handheld scanners only needed to be plugged into the OBD2 port, which provides power.
Next, I measured the cord’s length on the handheld scanners and the wireless range on the others. With the car running, I monitored the engine and other vital systems, and then disconnected the engine’s oil temperature sensor.
Finally, I checked the details provided by the scanner, fixed the problem, turned off the check engine light and erased the error code.
Then I hit the road to see if the scanner could display operating data such as engine speed, timing and coolant temperature. I paid attention to whether the device reported the data as numbers, graphs or auto-style gauges.
Regardless of which OBD2 scanner you use, you’ll need to crack its code. All fault codes have four numbers and a letter prefix:
Powertrain (P)
Body (B)
Chassis (C)
Undefined (U)
Of the roughly 5,000 diagnostic fault codes available, some are generic and apply to all cars, like air temperature and throttle position. For these, the numeric section starts with a 0. Others are specific to individual carmakers and represent either a special piece of hardware or a more in-depth analysis of the problem. These start with a 1.
For instance, if you get a P0098 code, chances are there’s something wrong with the engine’s intake air temperature sensor. By contrast, a Ford that displays a P1112 specialty fault code means that the intake air temperature sensor is reporting values intermittently and should be replaced.
