Bluetooth connected car diagnostic tool

 OBD (on-board diagnostics) is a system in the vehicle that monitors the performance of the vehicle's engine and emissions system. This code readers record real-time data and helps to detect any problems in the vehicle. OBD records the problems detected in the vehicle as DTCs (diagnostic trouble codes). The obd2 scanner diagnostic tool is a second-generation variant of this system.

Please follow the steps below to learn how to use the OBD2 scanner.

Step 1
Locate the DLC. in most cars, this 16-pin connector is located under the steering column near the left side of the driver's instrument panel. If you can't find it, check your owner's manual, which will certainly have details.

Step 2
Next, turn off the car before connecting the bidirectional scan tool to the DLC. Follow the scanner instructions to leave the car in on or idle mode to make the connection. Once a connection is established, you will see a message on the scanner.

Step 3
In some scanners, you will need to enter the Vehicle Identification Number (VIN). In some vehicles, you can find it under the bonnet or on the front of the vehicle. Again, if you can't find it, check the owner's manual or the purchase invoice at the beginning.

Step 4
You will now see the OBD code. Each DTC code starts with a letter, followed by a number. Generally the letters represent the positions as described below.

P (powertrain): engine, gearbox, ignition, emissions and fuel system
B (bodywork): airbags, power steering and seat belts
C (chassis): axles, brake fluid and anti-lock braking system
U (undefined): issues not covered by P, C and B.
Step 5
Write down the exact code displayed on the scanner and unplug the scanner. Check the code to determine if it is a minor or major problem, if it is not clear, check the code scanner literature, I believe it is in 99% of cases. If it turns out to be a major problem that you cannot easily fix, it is recommended that you go to a service station for professional help.
