3 Functions of the OBD-2 Port

Most modern vehicles have an OBD-2 port that plays many key roles in the use and maintenance of a car. This essential vehicle feature can help you to make the most of your car.

Let’s explore three common functions of the OBD-2 port in your vehicle.

What is an OBD-2 Port?
An OBD-2 port, also commonly known as an OBD-II port, is the computer at work inside of a vehicle. This dedicated system is designed to help monitor the essential components of a car. By doing so, it is able to help the different parts of the vehicle communicate with one another and is also able to help relay relevant information to the driver through a series of icons and lights.
An OBD-2 port is commonly found under the dashboard of the vehicle and can also be used to relay errors and problem information to a trained mechanic. Designed to keep your car operational and made to simplify troubleshooting for mechanics, the OBD-2 port is a staple in most modern vehicles.

3 Common Functions of an OBD-2 Port
These three common uses for an OBD-2 port can have a lasting impact on your vehicle.

• Supporting Emissions Testing

Emissions are a critical consideration for any car on the road. This is why the majority of vehicles require regular emissions testing throughout their lifespans. With emissions testing, experts can detect what is being released from a vehicle and make sure that the vehicle is in compliance. It is a type of testing we do to protect air quality.
In several states, emissions testing has changed to rely on OBD-2 information in more modern vehicles. This has replaced the original tailpipe test. However, tailpipe tests can still apply in some areas. Using a plug-in, experts can ensure that a vehicle is meeting appropriate standards using the OBD-2 port.

• Monitoring Vehicle Basics

Your onboard OBD-2 is designed to take in a lot of information about your vehicle and its habits. A good deal of this information is directly related to the movement and health of your vehicle.
There are several key components that your OBD-2 monitors, including your mileage and speed. This information can share a lot about the behaviors and health of a vehicle, which can be relayed to you or experts who assess your vehicle.
If trouble is detected, the OBD-2 port will illuminate the emergency warning lights on your dashboard.

• Controlling Vehicle Lights

Another amazing benefit of your OBD-2 port is the way it can interact with plug-ins to give you more insights and control. One great option is the Z-Flash Flasher, which is an OBD-2 or BCM plug-in that allows you to take complete control of the vehicles factory lights or emergency vehicle lights in your car.
When you use the plug-and-play technology of the Z-Flash Flasher, you can manage your lights using different patterns to successfully communicate with others. Fitted with a simple control, this allows you to take your lights and what they are capable of to the next level.


Use Your OBD-2 Port to its Full Potential Using the Z-Flash FlasherMany people think that an OBD-2 port is only useful for mechanics, but that isn’t true. You can upgrade your vehicle to make the most of emergency vehicle lights or to take better control of your LED warning lights using the Z-Flash Flasher plug-in.
