Owning a car can be expensive, often bewilderingly expensive. So having some insight into the state of repair of your car is a good thing in general. Even though you may not wish to attempt repairing your car at home. Having a good idea of what problems may be is good information to help you secure a speedy cost-efficient repair.

What is an OBD2 Scanner

OBD2 stands for On-Board Diagnostics, which is a system to detect and store information about problems within the car’s engine systems. A scanner is an interface that allows you to access this information in a useful way. They provide specific fault codes for the different components of the engine. These OBD2 Scanners are now reasonably inexpensive for models that give the basic information required. Most modern cars have an OBD2 socket located somewhere near the steering wheel. Your car’s handbook should show the position. This is often behind a flap or cover. An OBD2 scanner can be plugged in and read off any diagnostic codes that have been stored in the car’s memory.

How Can An OBD2 Scanner Help Me?

After scanning your car, the scanner will show any fault codes present on the vehicle. The codes produced are generic, lists of them are available online or from the manufacturer of your scanner. Checking what the codes stored in your car refer to gives you an idea of what has gone wrong. In some cases, these codes are for simple problems that you can rectify at home.

So whereas these tools were once the preserve of the motor mechanic, with lower costs and the increased use of technology within cars, they are a great addition to a home motoring toolkit.
