Car Diagnostics

Simplified in 3 Easy Steps

1. What is Car Diagnostics?

A car diagnostics check is a “health check” performed on your vehicle’s various systems and components. This can help you determine if there are any small or severe issues present in your car, and what exactly they are.

Typically, a car diagnostics check is carried out when your vehicle shows you a warning sign on the dashboard. However, as a preventive measure, car diagnostics checks can also be carried out on a periodic basis in order to avoid unexpected and expensive car repairs.

The best part is that you only need a small device — called an OBD2 scanner — which is affordable and let’s you access in-depth insights about your car from your phone! And all of this can be done in just a few minutes.

2. What do you need to run a car diagnostics check?

Equipment for a Diagnostics Check:

Whether you are a car beginner or expert, running a car diagnostics check is extremely easy and insightful. All you need is the right equipment which consists of two simple things.

1. OBD2 scanner

An OBD2 scanner is a small pocket-sized device that can be plugged into your car’s OBD port. This device reads out all of your car’s components and gathers data about your car’s health status.

2. Car Diagnostic app

Accessing your car’s data can be easily done via a car diagnostics app. All you need to do is download the scanner’s mobile app, and you will be able to see in-depth insights about your car.

3. How do you perform a car diagnostics check?

1. Run a Health Check

Running a health check means that the scanner will take a look at all of your car’s ECUs and make a list of any issues found in your car.

These issues will be shown in the form of OBD2 codes which indicate the type of issue present and the location of the issue.

The Carly app will provide you information about any OBD2 codes present.

2. Read out OBD2 Codes

Once the car diagnostics check is completed, the scanner will have read out all the OBD2 codes present in your car.

We recommend you go through all of the codes found to see if there are any critical problems that you need to take care of.

In order to help with this, the Carly app will categorize your car’s OBD2 fault codes depending on their severity.

3. Clear OBD2 Codes

There are two scenarios when you should clear your car’s OBD2 fault codes:

1. After running your first diagnostics check: It is possible that old codes are stored in your vehicle’s memory but are no longer an issue, so it’s best to clear them and see if they come back after a few days of driving.

2. After fixing issues in your car: You should clear all fault codes after repairing issues in your car and run another diagnostics check to ensure they are not present anymore.

What Can an OBD2 Scanner Do?

An OBD2 scanner (also called OBD2 reader) is a small device that can give you access to valuable insights about your car! Once you plug a scanner into your car, you will be able to visualize your car’s real-time health status through a mobile app.

Unlocking your car’s inner data will give you full ownership of your car so you always know what is going on and can prevent unexpected and costly repairs.
