Diagnose your car

In today’s world, new technology is being introduced continuously. So it’s no wonder that today’s drivers are now able to take advantage of advances in OBD2 scanning technology previously only accessible by professional automotive mechanics with expensive diagnostic equipment.

What is an OBD2 Scanner (Dongle) ?

OBD stands for On-Board Diagnostic. It’s the standardized system that allows external electronics to interface with a car’s computer system. So an OBD2 scanner is a tool used to check in real time if a car is working properly. The good news is that from the 2000s, most cars have universal OBD plugs.

Why you should use an OBD2 Scanner ?

If a vehicle's engine experiences a malfunction, the “Check Engine" light comes on. An OBD2 scanner can access the resulting trouble codes within the vehicle's diagnostic computer, or power train control module. This computerized hand held device can only interact with vehicles manufactured in 1996 and later. Using an OBD2 scanner is relatively easy, and accessing trouble codes only takes a few minutes.

What is an OBD Port and where is it ?

The OBD port is an electrical plug that OBD2 scanners, code readers, and other devices can be plugged into to access the OBD2 system. It is also the port that is typically used for state vehicle inspections. This port is typically located near or under the steering wheel column, although it is sometimes located near the center of the dash or center console, or under the glove box. If you’re having trouble finding it, check your owner’s manual.
