An obd2 scanner might be unknown to many people, however, it is one of the best devices that could help you monitor the health of your car and plan the maintenance accordingly.
While there are people who consider the obd2 scanner worthless and easy to use, these are just wrong assumptions. For most advanced cars, even if you take the car to an expert for maintenance, they could be using an obd2 scanner to check the current health of the car. Based on the result, further maintenance is planned.
With all these facts told, if you are a beginner, then, you should know that, if the obd2 scanner is not used in the right way, it could not help you analyze your car health. This is why you should not neglect any steps listed below.
There might be a small difference in the way you use different obd2 scanners based on their design. However, as mentioned, they are just small differences only.
Step 1: Your car would have a data link connector right under the control panel of your car. You need to plug in your obd2 scanner into this data link connector. Remember, your vehicle engine should not be running while plugging in the obd2 scanner.
Step 2: Once you have connected the obd2 scanner, you need to turn on the engine ignition and start the engine. Then you need to wait for the scanner to boot up. Remember, based on the model of your obd2 scanner, the time for boot-up might differ.
Step 3: After the obd2 scanner boots up successfully, it would prompt the user to input some answers to the questions. You need to enter all the details as requested, this could include the car model, engine type, etc.
Step 4: After you enter all the details as requested, you need to wait for the obd2 to process the details and to analyze and scan the diagnostic system of your car. If the process does not start automatically, you should press the start button, if you can’t find the button, then check the user manual for more information.
Step 5: Once, the scanning is completed, the obd2 scanner would display some codes on the screen, if the process was not successful, an error message would be displayed. No matter what, you need to note down the codes displayed on the screen.
Step 6: Now, you need to pick up the scanner manual that came with the obd2 scanner. Remember, every obd2 scanner will have a manual and this manual would have the codes and their details.
Find out what each code displayed on the obd2 scanner means. If you cannot find any code details, then you should Google it to find out. The codes for different cars might be different and therefore, you should not expect to find all code details in the scanner manual.
Step 7: After you have noted down the codes, you need to turn off the engine first, and then disconnect the obd2 scanner carefully. Remember while connecting and disconnecting the obd2 scanner, you should not be harsh. If you handle it harshly, the connector could break or come off. The obd2 scanner plug has 12 very delicate pins, they are not replicable, if the pins break, then you will have to replace the entire device.
Please note: Not all obd2 scanners are durable, some of them are fragile. Therefore, you should not carelessly place the obd2 scanner on the engine and walk off. Some obd2 scanners might malfunction if they fall, for the price at which obd2 scanners come, carelessness could do more harm. Apart from this, always connect the obd2 scanner first and then start the engine, do not try to connect the obd2 scanner while the engine is running, it could corrupt the obd2 software.
