Diagnosing Your Vehicle Requires The Right ToolsAutoGuide.comAutoGuide.com Sponsored ContentTue, September 8, 2026 at 5:26 PM UTCAdd us on GooglePhoto by Hrach Hovhannisyan/Shutterstock.comPhoto by Hrach Hovhannisyan/Shutterstock.comAn unavoidable truth applies to just about every vehicle on the road today: the more complex and advanced they get, the more important the diagnostic equipment becomes.That wasn't always the case. Years ago, figuring out what was wrong with a vehicle usually involved a handful of tools, a bunch of time, and knowledge of every system. Cars were simpler, but as the technology evolved, so did the tools. You need the right equipment to figure things out. That's where FOXWELL comes in.AdvertisementAdvertisementSince 2013, FOXWELL has been producing diagnostic equipment designed for the average vehicle owner, while still having what professional mechanics and heavy-duty truck technicians need. Its lineup ranges from simple OBD2 scanners to more advanced all-system diagnostic equipment, along with tools for specialized jobs such as battery testing.FOXWELL NT301: A Straightforward OBD2 Scannerdiagnosing your vehicle requires the right toolsFor many vehicle owners, the first reason to buy a diagnostic scanner is simple – because the check engine light came on. Seeing that light appear on the dash brings with it a sense of dread as you wonder how big the problem is and how much it's going to cost you. The FOXWELL NT301 OBD2 scanner is designed for exactly that kind of situation.You don't have to possess a great deal of automotive repair knowledge to get a lot of value out of the NT301. It's designed to be simple to use for beginners, as it helps you diagnose and solve problems quickly.It gives you the ability to read and clear diagnostic trouble codes, turn off the check engine light, do quick vehicle emissions diagnostics, and generally help you figure out what's going on with common issues your vehicle may be dealing with.AdvertisementAdvertisementIf you are fairly inexperienced when it comes to working on your vehicle and you need a helping hand to figure out why your check engine light is on or whether you can pass your next smog test, the NT301 is exactly what you need.Learn moreFOXWELL NT614 Elite: Moving Beyond Basicsdiagnosing your vehicle requires the right toolsIf you are dealing with a more complicated issue like your brake warning light turning on or a maintenance light that you can't seem to reset, it might be time to level up to FOXWELL's NT614 Elite.This device gives you access to four major vehicle systems: the engine, ABS, SRS, and the transmission. Basic code readers are often limited to the engine computer, but there are other systems that are electronic, too. This is especially true for maintenance that might otherwise require a trip to a repair shop. This includes things like ABS bleeding, EPB reset, oil reset, SAS calibration, and throttle relearn.AdvertisementAdvertisementFor the DIY mechanic, this is exceptionally useful.

Sometimes the battery is just bad. But how do you tell? The FOXWELL BT705 is a battery tester designed to help you find out. It allows you to test the battery, the starting system, and charging system so you can isolate the problem, as well as provide an easy way to test out CCA (cold cranking amps), internal resistance, and voltage.AdvertisementAdvertisementThe BT705 supports 12V batteries, as well as 12V and 24V starting and charging systems like you'd find in trucks and agricultural equipment. This is useful because replacing a battery based solely on a symptom isn't always the right answer. A vehicle that cranks slowly could have a weak battery, but it could also be a charging problem, faults in the battery, starting system, or charging system.The BT705 helps DIY car owners, home mechanics, and even professionals identify the true source of a problem before you start replacing parts, helping you reduce misdiagnoses and saving you money.Learn moreFOXWELL HD301: Diagnostics for Heavy-Duty Trucksdiagnosing your vehicle requires the right toolsBig trucks are a whole other matter and require very specific tools.
