Your Best Helper For Understanding the Health Status of Your Car: OBD2 Devices Modern cars are equipped with complex electronic systems and numerous sensors. Any malfunction that may occur in these systems may adversely affect the performance, safety and emission values of the vehicle. For car owners and automotive professionals, it is of great importance to be able to diagnose these faults quickly and accurately. At this point, OBD2 (On-Board Diagnostics II) fault detection devices are activated. OBD2 devices are connected to the vehicle's self-diagnostic system, allowing you to read fault codes (DTC - Diagnostic Trouble Codes) in various systems such as engine, transmission, ABS, airbag, monitor live data and, in some cases, perform basic testing and adaptation operations. There are a wide variety of OBD2 devices on the market, from a simple fault code reader to professional systems with comprehensive diagnostic and programming capabilities. Choosing the right device depends on the user's needs, budget and technical knowledge. Brands such as Launch, Autel, Topdon and Thinkcar offer OBD2 devices in different levels and specifications for both hobby users and professional workshops. In this comprehensive guide, we will take a comparative look at some of the best and most popular OBD2 fault detection devices on the market. By considering the main features, advantages, disadvantages, target user groups and general price December of these devices, we aim to help you choose the OBD2 device that best suits your needs. As Nitro Bilişim, we also support you in the supply and use of these devices. What is OBD2 and Why Do You Need a Device? OBD2 is an in-car diagnostic system that has become standard on most gasoline-powered and diesel vehicles produced after 1996 and after 2001/2004 (varies by country). It allows the vehicle to transmit failures detected by various electronic control units (ECU) and performance data to the outside via a standard protocol. An OBD2 device (also known as a scanner or fault detection device) accesses this information by plugging into the vehicle's OBD2 port (usually located under the steering wheel). Why Is an OBD2 Device Needed? • Fault Detection and Diagnosis: To find out the cause of a fault lamp (for example, Check Engine Light) burning in your vehicle, to determine the source of the problem by reading the fault codes. * Live Data Monitoring: Monitoring many important parameters such as engine speed, vehicle speed, coolant temperature, oxygen sensor values in real time. * Preparation for Emission Tests: Checking whether the vehicle's emission systems are working properly (I/M Readiness tests). * Basic Maintenance Operations: Some devices can support basic maintenance functions such as service light reset, electronic parking brake (EPB) retraction, battery recording. * Saving Money and Time: Avoiding unnecessary expenses and time loss by diagnosing simple malfunctions yourself or by having an idea about the problem before going to the service. * Used Car Check: When buying a used car, it can be used to detect potential problems or hidden malfunctions.
