What is the Use of OBDii Scan Tool for Vehicle?

1. OBDii scan tool can read throttle data of engine and display it to users. The engine is the "heart" of a car. The carbon deposition of the engine will cause damage to the engine. It will lead to engine acceleration failure, unstable idle speed, cylinder pulling and other faults. So with the help of OBDii scan tool, users can refer to the data to see if the engine is normal. So that can prepare cleaning and maintaining for the engine.

2. The vehicle scan tool can test the battery voltage. The battery is the wake-up device of a car. Only when the battery has electricity, the car can be officially started. So we often worry that the battery will suddenly lose power and can't fire the car. User cannot know this situation until they are in maintenance shop or the car is out of order. With OBD2 scan tool, user can know the voltage value of the ignition moment. With discharge voltage and start voltage, user can know the health of battery. So it is convenient to arrange maintenance in advance.

3. Another important role of OBDii scan tool is to read fault codes. The instrument cluster fault lamp is on during driving, which is generally a signal of potential danger. At this time, we all want to know what the fault is and is it a serious problem? With OBD scan tool, we can read the fault code and understand what the fault is. With different versions of OBDii scan tool and app, we can also learn more about the failure. It can play a very important role in the prevention of minor disease overhaul in the subsequent treatment.
