ScanMaster Review: Best Free OBD2 Software for Windows 10

If you’re in search of a powerful and user-friendly OBD2 software, look no further than ScanMaster.

In this comprehensive review, I’ll be exploring the features of ScanMaster and giving you my honest verdict on whether it’s the right software for you.

Let’s dive in!

Quick Review

Vehicle Coverage

The software supports all OBD2 vehicles. This includes all OBD2-compliant cars and light trucks.

However, compatibility may vary depending on the specific make and model of the vehicle. 

For example, there are limited specific functions for Asian vehicles such as Nissan and Toyota.

Interface

ScanMaster software is designed to be the best user-friendly scanning program; even inexperienced users can navigate comfortably.

See ScanMaster interface below:

It is simple to find the information you are looking for.

As you can see, the main menu display has options such as:

• trouble codes,
• live data graph,
• actuator,
• vehicle info,
• system status,
• PID config
• and O2 sensors.

Here is the interface of the live data function:

It’s not customizable but it allows you to see 4 parameters at the same time.

However, the software may be challenging for those unfamiliar with diagnostic scanners. 

For example, it will take you time to find certain functions such as DTC search or Dashboard with gauges.

The icons are small; therefore, it’s not easy to spot – see the picture below:

Performance

1. Quick trouble code reading

The software is able to connect to OBD2 devices quickly and read, analyze then clear codes. You can pull stored, pending and permanent codes.

On some occasions, permanent codes are not displayed.

Using the ELM327 Bluetooth adapter, I managed to identify and clear error codes for catalytic converter problems on a 2012 Honda.  

Important note: To clear codes, first fix the issue on your car and turn on the ignition. Ensure that the engine is off.

2. Very useful live data function

Information collected from live data is very important.

It’s helpful in tracing the origin of problems by revealing faulty parts and correcting error codes.

You will save time and money by identifying your vehicle’s problem straight away rather than guessing. This way, you can easily fix your vehicle and avoid unnecessary costs.

3. Impressive actuator tests

With this feature, you get extensive and additional analysis to help you pinpoint your car problems accurately with ease through active tests.

Note that this is only possible on vehicles whose ECU supports mode 8.

At $20, you can buy an ELM327 USB adapter and utilize ScanMaster to narrow down your vehicle’s problems for easy fixation.

4. A little bit slow when starting up

Using Windows 11 operating system, I noticed that the software doesn’t open immediately when you double-click on it.

I have to wait for 10-20 seconds before it responds.

How To Set Up?

Installing ScanMaster can be tricky and time-consuming if you don’t know the right place to download it.
