So what is it? An onboard diagnostics (OBD) system helps identify engine problems by connecting directly to your vehicle’s computer through a port located under the dashboard. It then reads the data within the car that you wouldn’t normally have access to otherwise. The second generation of scanners, often referred to as OBD2, made accessing these codes easier than ever before, with all kinds of helpful features like code definitions and generic trouble code lookups.

Clearing codes with an OBD2 scanner only takes a few seconds after you connect the device and turn on your car’s ignition. This is important for a quick diagnosis. With information at their fingertips, technicians are able to quickly identify potential issues, allowing them to troubleshoot more efficiently and get customers back on the road faster!

2. Types of Obd2 Scanners

There are several different kinds of OBD2 scanners. All these devices have the same basic purpose: to detect and diagnose issues with a vehicle’s onboard computer system. But they differ in how they approach this task.

The handheld scanner is the most popular type of scanner for DIY mechanics or auto repair shops. It can read codes from all sorts of vehicles, including cars, trucks, SUVs, and even boats. The handheld device has an LCD screen that allows you to view real-time data and diagnostic trouble codes (DTCs). You can also reset service lights and erase fault codes using this type of scanner.

On-board diagnostics (OBD) readers come in both wired and wireless versions. They connect directly to your car’s OBD port, so you don’t need any additional cables or software updates as with the handheld version. Plus, they’re small enough to be tucked away out of sight when not in use. This makes them ideal for those who want a more permanent solution than a handheld scanner but still want access to their vehicle’s data at all times.

Regardless of which kind you choose, an OBDII scanner will help you maintain your vehicle’s health by providing quick access to important information about its performance and helping identify potential problems before they become major repairs down the road.

An OBD2 scanner is an important tool for any mechanic. It can help detect, diagnose, and resolve issues with a car’s performance quickly and accurately. So what does it do? Let’s take a look:

Firstly, the scanner will read diagnostic trouble codes (DTCs) from your vehicle’s computer system. This gives you an instant indication of where to start looking when diagnosing problems. Here are some things that an OBD2 scanner can tell you about your car:

  • Check engine light code readings
  • Live data stream from sensors
  • Results of the Readiness Test
  • Evaporative emissions monitoring
  • Vehicle speed tracking

The scanner can also reset your check engine light after repairs have been made. Doing this without the right tools could be time-consuming and may not even work properly in some cases. With a scan tool, this process is much simpler and more accurate, which makes it easier for mechanics to get the job done efficiently. Plus, if there’s ever a need for future diagnosis or troubleshooting on the same vehicle, all relevant information is stored on the OBD2 scanner, so it’s easy to retrieve at any time.
