OTC 3209 OBD-II Review
The OTC 3209 OBD-II scan tool can be purchased online for about $100, depending on the seller. This is a very average price, and helps the tool stay in the same range as similar tools that hold comparable features and capabilities.
Advantages of the OTC 3209 OBD-II
Clear backlighting: One of our favorite features on the OTC 3209 OBD-II scan tool is the clearly lit and readable display. By utilizing a backlit display, you’ll be able to clearly see the information, and you shouldn’t have to worry about sunlight and glare affecting your vision, and you’ll also be able to clearly read the display if you are using the tool in a dimly-lit garage.
Live-data mode: Live data mode is extremely helpful for accurately diagnosing engine problems, and the OTC 3209 OBD-II gives you quick and convenient access to streaming information, straight from the engine. Live data features can give you a lot of points related to engine health and performance. While it may take some learning to fully understand this function, once you know the hows and whys, live data can help you maintain a strong, efficient engine.
Check your anti-lock brakes and airbag lights: If you own a basic code reader and your ABS (anti-lock brakes system) or SRS (airbags, aka Supplemental Restraint System) lights come on, you may be forced to go to a mechanic for a proper diagnosis. The OTC 3209 OBD-II tool, however, can deliver clear information related to the issue. There is a catch that you’ll want to know about before using the ABS and SRS feature, so keep reading and find out why this function may not work for your vehicle.
Code definitions provide enhanced information: Many tools will give you the basic codes but not the information related to the error. The OTC 3209 OBD-II not only gives you the code, it also gives you the definition. For example, other tools will simply read P0300, and you’re on your own to find out what that means. The OTC 3209 OBD-II, however, will tell you it mean a random misfire was detected. Unlike some tools, this one won’t give you possible solutions, but it will point you in the right direction.
Disadvantages of the OTC 3209 OBD-II
ABS and SRS for domestics only: This is pretty common among scan tools, and a regular complaint from online reviewers, but the anti-lock brakes and airbag diagnostics only work on domestic vehicles. If you drive an Asian or European model, you’ll be SOL if you need to diagnose the SRS.
No solutions provided: While the code definitions are very handy, it would be nice to see recommended solutions as well. Many other tools in the same price range not only tell you what is wrong with the vehicle, but give 3 or 4 common fixes. Depending on the issue, some tools can recommend you to clean the MAF sensor, replace the thermostat, or simply make sure the gas cap is secured. The OTC 3209 OBD-II, however, won’t provide you with this direct information.
Final conclusion
Whether you are looking for an advanced scanner or a basic tool for diagnosing and erasing error codes, the OTC 3209 OBD-II scanner will be able to meet your needs.
As long as you’re not hoping to use the ABS and SRS functions on a foreign vehicle, and you don’t mind researching your own solutions, you’ll have a tool that is practical, versatile, and not too pricey.
