Ensure a Smooth and Safe Driving Experience


Why should everyone do car diagnostics?

Car diagnostics are an essential aspect of vehicle maintenance. Regular diagnostics not only keep your car running smoothly but also help you save money in the long run. Early detection of potential issues through diagnostics can prevent costly repairs and enhance road safety.

In this blog post, we’ll explore three crucial steps to successful car diagnostics to help you keep your vehicle in top shape and enjoy a trouble-free driving experience.

Step 1: Have the gear ready

Before diving into the diagnostic process, gathering the necessary tools and equipment is crucial.

The most essential tool is the software communicating with the vehicle. OBD Auto Doctor, our user-friendly diagnostic software designed to aid in diagnosing emissions and driveability malfunctions, connects to your car’s onboard computer and retrieves the diagnostic information.

Other essentials include a reliable OBD dongle/adapter and a notepad for notes.

Having these tools readily available will streamline the diagnostic process and help you address any issues efficiently.

Step 2: Run vehicle diagnostic software

Modern vehicles come equipped with sophisticated onboard computers that generate error codes whenever an issue arises. Utilizing vehicle diagnostic software, such as OBD Auto Doctor, is a game-changer in identifying and understanding these codes. Here’s how this software can be a valuable asset:

Read and Analyze OBD2 Trouble Codes

OBD2 Trouble Codes provide valuable insights into the specific problems your vehicle may be experiencing. The diagnostic software reads these codes, allowing you to interpret and understand the issues. From engine misfires to faulty sensors, the OBD2 Trouble Codes act as a roadmap to pinpoint potential problems quickly.

Access Other Car Diagnostic Services

In addition to reading trouble codes, advanced diagnostic software can provide access to additional services that provide a comprehensive overview of your vehicle’s health. Such insights enable you to identify irregularities and address them before they escalate.

These other vehicle diagnostic services include, for example:

  • Diagnostic Monitors (advanced diagnostics with specific data)
  • Performance Counters (tracking of event counts)
  • Live data streaming (real-time monitoring of various parameters like temperatures, pressures, fuel efficiency, for example)
  • Readiness Monitors (emission readiness for car inspection)

Performing these car diagnostic checks with OBD Auto Doctor will take less than 5 minutes. However, making it a regular habit can save you a lot of time and money in the future.

Step 3: Identify and repair the issue

Once you’ve gathered information from the diagnostic software, the next step is to identify the root cause, whether you plan to fix the problem yourself or seek professional assistance.

First, identify the issue. The diagnostic trouble code description is typically a good starting point. In best cases, the description will tell you precisely the problem. Next, research the internet with the specific trouble code your car reported. You may find valuable repair advice from car model-specific forums or online communities. You might also discover a typical, well-documented pattern of failure in the automotive community.

Second, visually inspect to find and verify the faulty component or system. Look for cracks in wires, corrosion, burn marks, loose connectors or terminals, and such.

Performing the required repairs may include checking and replacing faulty components, clearing error codes, or performing routine maintenance tasks. Follow manufacturer guidelines and, if needed, seek professional assistance for complex issues.


Car diagnostics play an important role in maintaining the longevity and performance of your vehicle. Following these three essential steps empowers you to address potential problems proactively.

Regular diagnostics not only save you from costly repairs but also contribute significantly to your vehicle’s overall reliability. Make car diagnostics a routine part of your maintenance schedule, and enjoy a worry-free journey on the road.
