The A-Z of Your Car’s OBD (OnBoard Diagnostics)

Cars have always been special especially for true motorheads and car enthusiasts. With people spending loads of time and energy improving and upgrading their cars often, making sure you cover the basics only makes sense.

Features like a ghost immobiliser fitting provided by various companies like BSWC Auto Security upgrade a vehicle for better fuel economy and improved car performance. With so many upgrades on the market, doing whatever you can for your car will make your vehicle all the more better.

This makes features like onboard diagnostics important.

OBD or onboard diagnostics is the car’s self-diagnostic system that monitors the vehicle’s sensors and subsystems to provide real-time data and diagnostic trouble codes for vehicles. In simple terms, it is a computer-like device inside the car that provides information about the vehicle’s performance.

While many car enthusiasts are usually aware of most components of their beloved vehicle, if you’re not familiar with OBD and wish to know more about it, you’ve come to the right place.

We’ve put together a short guide on all you need to know about your car’s onboard diagnostics to fully understand how it works for your vehicle.

So without further ado, let’s take a look!

What Is OBD And How Does It Work?

An OBD is a device fitted in your vehicle that provides a comprehensive report on your car’s performance. Although there are many different types of versions of onboard diagnostics for a vehicle, the basic system includes a central system, sensors, and a monitoring system with standardized complete access and readability of the car’s performance.

The main component of the OBD is the ECU. The ECU collects information from various sensors of the vehicle to control the parts of the vehicle or to monitor issues. Each of the sensors sends the ECU codes which interpret the signal.

In case any of these codes fall out of the normal range the information is saved by the ECU as a code called the Diagnostic Trouble Code or DTC. The DTC then sends a signal to the vehicle’s dashboard to turn on the appropriate lights. These lights are known as Malfunction Indicator Lights to provide an early warning. This determines the condition of your vehicle based on the status of the light.

All the data and codes collected by ECU can be assessed by the Diagnostic Link Connector which acts as the point of access for the car’s OBD.

Advantages And Applications Of OBD

OBD is commonly used in most modern vehicles and is used to diagnose vehicle problems. However, with the development of the different types to provide more 

coverage, there are many applications and advantages of CBD.  

1. Driver Behaviour Monitoring

The automotive industry has increasingly relied on OBD to understand and monitor driver behaviour. Since there are a few car manufacturers that provide reduced premiums for drivers with proof that they practice safe driving.

With this, companies also have the choice to monitor the driver’s adherence to safe driving practices to reduce liability issues during accidents and other events.

2. Tests Emissions

OBD II testing is a common method of testing vehicles in many parts of the world. Since this system closely monitors vehicle emissions, keeping an eye out for emission-related trouble codes becomes easier.

This becomes important as one needs to ensure compliance with Government set rules and regulations around vehicle emissions.

3. Helps Keep An Eye On Metrics

For those who keep a close eye on their vehicle’s specifications, especially performance-related, OBD is a great tool. Since many of these metrics aren’t measured or displayed with a standard vehicle, an OBD system can prove really useful.

With the option of customisation and display tweaks, many people can even get these metrics broadcasted or displayed on their phones.

4. Better Overall Performance

From fast diagnosis to improved compliance with reduced costs, OBD is essential for every car owner to leverage their performance. While many upgrades do bring about great changes in their vehicle, OBD also helps identify potential problems to ensure that the vehicle is in good condition at all times.

While the basic OBD systems do function extremely well, more advanced upgrades let every car reach its full potential. This makes looking for the appropriate car diagnostics and repair company essential.

To Sum Up

While considering your remapping, DPF or a ghost immobiliser from Birmingham or any other place, make sure to take a step back and also look at your vehicle’s OBD. While most cars may come with a basic model, investing in an upper variant will always work in your favour.

After this, keeping yourself informed with the basics of how the system works can ensure that you keep your car in good condition while also helping it reach its full potential. This makes OBD an important component everyone must pay attention to.
