Unveiling the Mechanics’ Secret Weapon: The Power of Car OBD2 Scanners
To use an OBD2 scanner, you simply plug it into the OBD port in your vehicle. This is the same port a state emissions inspector will use when you get your annual inspection. The location of the port can vary, but it is usually underneath the steering wheel on the driver’s side. The scanner can then read the error codes stored in the car’s onboard computer. These codes typically start with a letter (such as P, B, C, or U) followed by a number. The first number is a manufacturer code and the second indicates what part of the vehicle has an issue.
Most OBD2 scanners are battery-powered and work when they are plugged into the OBD2 port in your vehicle.
