What is a Car Scanner? Here are its Functions, Uses, and Recommendations

In the era of modern cars like today, car systems are becoming increasingly sophisticated. This can be marked by the emergence of car scanners. So what does this component function as? For more details, please pay attention to the following review.

What is a Car Scanner? 

A car scanner is an electronic device used to read signals of malfunctions in the engine and modern car systems. 

Functions of a Car Scanner 

Here are some important functions of a car scanner that you need to know. 

1. Diagnosing engine problems

As previously explained, the main function of a car scanner is to diagnose problems that occur in the car's engine. When the engine has issues, the sensors within the engine will send error signals to the car scanner. 

2. Monitoring engine RPM

Next, the car scanner also functions as a monitor for the engine's idle RPM. When the RPM is too low or too high, the car scanner will capture signals indicating that there is a problem with the engine.

3. Facilitating MAP sensor inspection

The car scanner also facilitates the inspection process of the MAP (Manifold Absolute Pressure) sensor. As is known, the MAP sensor measures the airflow in the engine's intake manifold, which plays an important role in maintaining the correct fuel-to-air ratio for engine efficiency. If this sensor has issues, fuel consumption will be wasteful. 

4. Monitoring car performance

The car scanner can also function as a real-time monitor of car performance. This way, car owners can see various parameters, from wheel speed, oil pressure, to engine temperature. 

5. Saving time and money

The existence of a car scanner allows car owners to know the health condition of the engine and car systems. This way, car owners can conduct initial inspections and determine whether the car needs repairs or not. This certainly has a significant impact on time and cost efficiency. 

How to Use a Car Scanner

Here is a guide on how to properly use a car scanner.

1. Prepare the car scanner, then connect the scanner connector to the car. Make sure the car is in the ON position during installation.
2. If using a scanner connected to an app on a smartphone, wait for the scanner to connect to the app. Ensure Bluetooth on your smartphone is active.
3. Then select the menu related to checking the car's condition, such as brake system sensors, fuel, and so on. If a malfunction occurs, the DTC code will appear during the scanning process.
4. Then continue the inspection process to improve the car's efficiency.
5. If you are using a car scanner without an app on your smartphone, simply turn the ignition key to the ON position. Then press the red button (scanner power).
6. Next, press the OK button, and select the car manufacturer origin, whether from Europe or Asia. If there is a malfunction, the DTC code will appear during the scanning process.
7. Then continue the inspection so that the DTC codes can be resolved quickly, thus improving the car's efficiency.
