What is the Bluetooth-enabled OBD2 device?
The Bluetooth scanning device connects the vehicle’s OBD2 Bluetooth system to identify the major issues that have taken place inside the car. Most often, It applies the compatibility checking module to the next level. This solitude of mechanisms is transmitted to the main device, making Bluetooth the major component. The Obdii pin is more or less responsible for connecting the scanning device. OBD diagnostic interface makes sure that the device is connected to the vehicle.
How to Pair OBD2 Bluetooth Device with the vehicle?
You must remember some methods to create an inclusive bond between the Bluetooth device and the car. The module that is named the SMTPS is the most futuristic and amiable version of the Bluetooth OBD-II port. Then you need to scan the scanner by turning on the BlueTooth option in the device. In order to make pairings, always input a harmonious code. A Vehicle Identification Number (VIN) is always required when you are trying to make a connection. Ensure that the car is Bluetooth OBD2 compatible otherwise, it won’t work.
Then Locate the vehicle’s OBD II diagnostic port and plug the scanner in that port as you are trying to connect a Bluetooth obd-ii scanner so you can remotely operate the entire mechanism. The distance should not be more than a few meters; otherwise, the connection will get weaker, and it may trouble the relationship, and the entire scanning function and the process will be nipped in vain. Make sure to activate the ignition key, as both methods work simultaneously. The engine will be off, but this yields incredible power. After attaching the scanner, go to your settings option and then to the wireless & networks option, and gradually you will reach the Bluetooth settings. Then activate the Bluetooth juncture, scan for nearby devices, and try to make a solid pair for the phone. Thus, the process relies on a robust, invisible ray that makes the connection possible.
The complete process of OBD2 Bluetooth Pairing
The pairing of the OBD2 Bluetooth scanner with the vehicle is the most unique and sleek process that can be proved essential in diagnosing the fault codes of the car. Here is the full process of pairing Obd2 Bluetooth,
Check Vehicle Compatibility
The very first stage is to make sure that the vehicle is compatible with the Obd2 Bluetooth pairing. Let me tell you a mind-boggling fact about recognizing the compatibility of the progressive OBD II Bluetooth device with the car. Vehicles that are made after 1996 are mostly prone to be OBD2 compatible cars, and if you want to check the compatibility, then you can see the code under the hood of the main engine. There you will find the OBD2 compatibility measures. In fact, you will be able to find out the ins and outs of the vehicle in that manner.
Connect the device
After you find the car’s compatibility with the OBD2 Bluetooth device, the next step is to connect that device with the vehicle. You can manually connect the device, or you can also make a coil of undisputed and invisible channels that paths through the connection between the device and the car.
It is known to everyone that the Bluetooth device can be connected to a car from a long distance. So now it is time to connect the device manually by following some steps. You need to select the “Settings” option and then go to the “Wireless & Networks.” Option and click on the modified icon. Then choose the option written as the “Bluetooth Settings.” After you have tuned the Bluetooth compatibility, the system will automatically scan for any devices around the multitude of the car.
Get Pairing Code
After finding the clearing region, you will see codes like 1234, 0000, 1111, and 9999. If you visit one of these codes, try connecting the Bluetooth device by using that code. The code will be smooth and resilient, and harmonious with the device. Connect the device and try to find out the faults in the vehicle.
Why does the OBD2 Bluetooth scanner fail to pair?
There are several actual causes for the failure of the Obd2 Bluetooth Device pairing with the car. Eventually, the prospects must be in an obd Bluetooth code reader standard to become a successful operation. Let us acquaint some of the major causes of the failure in the pairing,
- There might be other reflective Bluetooth devices in the path between the OBDII Bluetooth Device and the car, like the speaker, headset, or smartphone, that create a nuisance in connecting the device with the car.
- Always keep in mind that no other app is running in the background. Otherwise, it will impede the connection between the car and the device. So you must close the app before pairing.
- Sometimes the password is not right, and that fails the connection between the scanning device and the car. Try some passwords that have been given in the next section of the article.
- If none of the mechanisms works, try rescanning the device and using another password from the pipeline. The first stage is to alternate the pairing codes and then pair the scanner with a different device. Some faulty cloned code might be yielded during the process. Always avoid those fault codes.
- The failed pairing might occur due to the scanty amount of time the Bluetooth scanner remains unrecognized and discoverable. The elm327 Bluetooth scanners come to the spotlight when you plug them into the OBD2 port,
- If the connecting procedure is performed within one minute of plugging, then the pairing shouldn’t be any issue. If the scanning device is not connected, there must be a fault in the main unit, and that unit must be changed to diagnose the whole system correctly.
Some other OBD2 Bluetooth pairing codes
The elm327 Bluetooth device is incorporated with some of the strict pairing code, and the set of probable and deployable instructions is imperative for building harmony between the car and the scanning device. Suppose you cannot research the pairing code. The most usually applied code in the elm327 device is code number 1234. Some codes are 1234, 0000, 1111, and 9999, which might also be effective in making a bond between them.
Hi, I am Henry, the owner of this website. If you are a DIY car enthusiast like me and are looking for an all-purpose OBD2 scanner, you’ve come to the right place. With 5+ years of experience in the automobile industry, I have in-depth knowledge about most of the OBD2 scanners regarding their software versions, firmware, features, updates, and compatibility. I love reviewing these gadgets after using and testing them personally. As a result, I always try to provide my honest opinion on the overall product quality.
