What Does Obd2 Scanner Do?


The OBD2 scanner is the quickest and reliable vehicle’s diagnostic system. But, what does obd2 scanner do? It is used to detect mechanical and electrical failures in vehicle engines. The failures affect the emissions of polluting gases from the vehicle to the environment. The outcomes of the OBD2 system are much more extensive than other systems.

OBD2 scanners open the door of advanced diagnostics to professionals and amateurs. You can stay alert with the vehicle’s issues in real-time. So, you can fix the issues ASAP to avoid annoying trouble on the road.

What does obd2 scanner do?

OBD2 scanner gives you access to both live and stored data. It can do the following tasks for you with accuracy:

Transmission diagnostics

Most of the common error signals come from the vehicle transmission. You can face overheating problems, low fluid or a malfunction of the control system. An OBD2 scanner perfectly diagnoses the main issues. There are a variety of OBD2 scanners with different functionalities. Among them, Fixd and Hum is the reliable OBD2 card diagnostic tool. They work through the OBD2 port but there is also some difference between fixd and hum which make them different from one another.

ABS / SRS Airbag control

The ABS stores information about wheels, brake fluid, and antilock detection. Systems that control one of the most important functions of your vehicle. The SRS system or airbags, speed monitoring and more data ensures safety in emergency. These systems are vital components for your safety, in which case, an OBD2 scanner can detect if they are faulty or function smoothly.

Tire pressure monitoring system

TPMS is a system whose main job is to inform the driver about the pneumatic pressure inside the wheels. Under normal conditions, the OBD2 system will alert the driver if the pressure in either wheel drops below 25%.

Oil Indicator Light Reset

After checking the oil levels in your vehicle and having completed the proper maintenance, the oil light may remain on. In this situation, an OBD2 scanner is the perfect to reset the lighting alert and know through its interface if all works correctly.

Battery test

Testing the battery is an important part of car maintenance. It avoids unpleasant situations, such as your car being left lying in the middle of nowhere because it won’t start. With an OBD2 diagnostic machine, you will have a detailed and accurate reading about the battery. So, you can replace or recharge the battery before going on a long trip.

In addition, if you are the owner of an automotive workshop, you can diagnose customer’s cars. It gives an important added value to your customers. They will appreciate a reliable solution and undoubtedly come back for more.

Real-time and remote programming

Stay updated with your device wirelessly from anywhere. This will keep your device up to date, which ultimately provides more accurate and reliable reading. If your family is on a trip with your car, you can know if there are any vehicle issues.

ABS, misfire, and live information

With a clear diagnostic readout of the ABS and all engine misfires, you can ensure your car’s good health and prevent failures that can become more complicated later. So, you can escape annoying issues during the trip.

Analyze anti-lock braking system

Your vehicle’s anti-lock system is made up of several important systems. According to the speed of your car, these calculate the braking pressure to stop it in the minimum possible distance and time, but without dangerously blocking the tires. With an advanced OBD2 scanner, you will analyze accurate data in real-time on braking speed and other advanced functions related to these systems.

Shows CEL, RPM, Speed, Pressure, Coolant Temp and Live Map

When an engine misfire occurs, a large number of different parameters may have to be measured. With Freeze Frame technology, an OBD2 scanner includes RPM, speed, coolant temperatures and much more.

Measure fuel consumption

Defining the condition of the oxygen level in combustion is vital to make sure that vehicle is running well. If the O2 sensor fails to work, this can cause engine problems to be read slowly or inaccurately. A scan tool can read the vehicle’s emissions and understand if all the ratios are suitable.

Presents engine performance

An effective OBD2 scanner allows you to test voltage, current, continuity and give you a rough estimate of battery life. It is also a tool capable of jointly verifying the operation of the different systems related to the engine to guarantee good performance. Even if you can’t read the oil temperature when an error code appears, you can quickly assess if it has to do with this variable.
