Has your car broken down again? Well, that might mean another trip to the mechanic is required. And one thing your mechanic might use is vehicle diagnostic software.

This is software that presents engine and emission control diagnostic details provided by the car’s Onboard Diagnostic (OBD) system in numerical and graphic forms.

Then users can identify mechanical faults and fix them.

Before you invest in car diagnostic software, first check if your vehicle is OBD 2 compatible.

Modern European and U.S. cars have On-board Diagnostic systems that monitor engines and emission-related controls.

To check your car’s compatibility, have a look through its manual. You can usually find OBD 2 slots around the dashboard, gear stick, or handbrake.

If your car is OBD compatible, you’ll need either a USB connector cable or Bluetooth-enabled OBD adapter scan tool for laptops or other devices.

You can use an adapter scan tool that slots into the OBD 2 port if your laptop is Bluetooth enabled.

With a suitable connector cable or scan tool, you can then connect your Windows PC or mobile to the OBD system and make the most of this car diagnostic software.

What is the best OBD software?

TOAD Scanning Tool

Toad is one of the best OBD tools out there. It allows you to run a full and comprehensive check on your vehicle.

TOAD is an affordable diagnostic software that works with both OBD1 and OBD2 automobiles, covering most car models. To get the most out of this life-saving program, however, you should match it with the proper ELM327 adapter.

The good news is that you can get the adaptor from TOAD, saving time from looking elsewhere.

Using customizable graphs, this tool makes it possible for you to understand the state of your car’s systems and helps you solve all the possible problems that may occur.

One of the most powerful features is the possibility to tune and reprogram your car ECU chip data.

Other important features include: diagnosing common problems, optimizing fuel consumption, showing and fixing many problems without a professional mechanic, revealing your car’s CO2 emissions.

Let’s quickly look at its key features:

  • Clear your Check Engine Light
  • Pass Emissions Testing
  • Supports multiple controller modules (ISO-9141, ISO-14230, ISO-15765 CAN and more)
  • Supports multiple OBD protocols (OBD1, OBD2, EOBD, JOBD, ADR, and JDM)
  • Monitors real-time data (including engine temperature, O2 value, RPM, speedometer, battery voltage, ignition angle, etc.)
  • Analyze fault codes and get solutions (extensive OBD2 code analysis from a built-in database of over 15,000 fault code definitions)
  • ECU Chip Tuning, Correction, Remapping
  • ECU Map Editor (contains 14,000+ optimized car ECU map files)

Alternatively, you might save it and perform the analysis later. In any event, TOAD gives you enough time to do an accurate analysis of the real-time data.

The program, however, only retrieves codes from the engine and gearbox systems. So you won’t know whether the fault is in another system, such as ABS or SRS.

In order to answer all your needs, the software comes with a full guide that will help you detect and understand the errors and problems found on your vehicle.

Moreover, it will give you some tips on how to fix these issues in the most effective way.

The EOBD Facile application is based on the OBD2 standard for engine and transmission computers. This specification was enforced on manufacturers, which means that all automobiles, to varying degrees, are compatible.

The downside is that this software is strictly for diagnosis and cannot be used to modify an ECU. Unfortunately, the airbag, ABS, and ESP computers are not covered by the EOBD standard. Only the manufacturer’s kit can perform a diagnosis in this instance.
