Diagnosis Software For Cars

Free diagnostic tools may only work with cars sold in one country or another—or even just those made by one manufacturer or another. For example, some brands of cars are compatible with any OBD2 scanner sold outside of their home country (such as Audi in Germany), while others will only work with scanners from within their home country (such as Volkswagen).

In this guide, we review the aspects of Diagnosis Software For Cars, best car diagnostic software for pc, best car diagnostic software for pc, How can I use my laptop to diagnose my car, and What is the best scanning tool for cars?

Diagnosis Software For Cars

For many years mechanics have used a hand-held diagnostic tool to read data from the vehicles computer system, known as the OBDII port. This has been very beneficial in helping them to identify problems with cars and trucks. However this technology has now improved, so that it is possible to connect your laptop or tablet directly into your car’s computer system and perform a diagnosis without the need for any special equipment.

The OBD2 diagnostics can be performed on a vehicle using a hardware device and software.

To perform OBD2 diagnostics on a vehicle, you will need an OBD2 adapter and software that supports the type of vehicle you are working with. This can be done by using a hardware device and software.

OBD2 is a standard for diagnostics in cars, trucks and motorcycles.

Diagnostic software is widely available on the internet, but the quality of this software varies.

Diagnostic software is widely available on the internet, but the quality of this software varies. Some diagnostic tools are free and some are not, so it’s important to consider which one is best for your needs.

Some diagnostic tools are better than others in terms of accuracy, ease of use, reliability and price. If you’re looking for something that is reliable and easy to use, then our car diagnostic scanner tool should be your first choice.

Some companies charge fees for their software and others give away their software for free.

Some companies charge fees for their software and others give away their software for free. Some companies provide free access to their diagnostic system over the internet, while other companies charge for access to their diagnostic system.

Some car manufacturers provide free access to their diagnostic software over the internet.

Some car manufacturers provide free access to their diagnostic software over the internet. This can be especially helpful for newer vehicles that do not come with a diagnostic cable, or if you need to test a vehicle from another manufacturer.

GM, Ford and Toyota all offer free online diagnostics for most vehicles sold in the US. If your vehicle has a warranty you’re still covered under, but be aware that aftermarket parts on your car may void your warranty and make it difficult to get repairs done at a dealership.

Other car manufacturers charge for access to their diagnostic system.

Some manufacturers charge a yearly fee for access to their diagnostic system. Some manufacturers charge a monthly fee for access to their diagnostic system. Some manufacturers charge a per-use fee for access to their diagnostic system. And some manufacturers charge a one-off fee for access to their diagnostic system.

Free diagnostic software is more commonly offered by workshops that want to attract customers and build a database of vehicle information.

Free diagnostic software is more commonly offered by workshops that want to attract customers and build a database of vehicle information. These workshops want to provide their customers with the best service possible, and so it makes sense for them to offer free diagnostic software.

This can work in two ways:

  • If a workshop’s customers use their free diagnostic software on a regular basis, then the workshop can use this information to improve its own service. For example, if most of the workshop’s customers have experienced problems with their cars’ headlights or engine lights coming on at night time, then this could suggest that there might be some kind of fault with the electrical system in certain models of car (e.g., they may not have enough power). In this case, it would make sense for the workshop owner/manager to invest some money into buying new parts so as he can replace things like faulty wiring harnesses and alternators when they break down or stop working properly within 12 months’ time period – instead than waiting until after they’ve broken down completely before fixing them! This way he knows exactly where his money should go because he’ll know what needs fixing first based upon how often people report similar issues across multiple different models; so even if there isn’t an obvious fix right now then at least we’ll know which direction we need go next! It’ll ensure nothing goes unnoticed next time around too!”

Free diagnostic software is often provided by suppliers of replacement parts.

Free diagnostic software is often provided by suppliers of replacement parts.

Suppliers of replacement parts want to sell more parts, so they provide free diagnostic software to help you diagnose the problem so they can then sell you the part you need to fix it.

Free diagnostic software is also provided by tools suppliers as an incentive to buy their tools.

Free diagnostic software is provided by tools suppliers as an incentive to buy their tools. Free diagnostic software is also provided by tools suppliers so that you can test the tools and their functionality.

Most diagnostic software only works with vehicles sold in a particular country.

While diagnostic software is an essential and helpful tool for most mechanics, it’s important to understand that not all diagnostic software is compatible with all vehicles. The best way to ensure that you have the right kind of diagnostic software for your car is by choosing one that is made specifically for your type of vehicle and sold in a country where the car was manufactured (if applicable). Many manufacturers offer different types of diagnostics depending on the region where they’re sold.

Free diagnostic software is widely available, but it may not work with your vehicle if it was sold in another country.

If you’re not sure which software to use, a good place to start is by using the diagnostic software that came with your car. If that doesn’t work, it’s also possible to find free diagnostic software online. This can be more convenient than paying for a subscription-based service, but it’s important to remember that different vehicles might require different tools.

Our Recommendations for OBD2 Software

1. TOAD

When it comes to getting the right OBD2 software for your vehicle, you want something that is as comprehensive as possible.

Since many modern cars have proprietary codes and systems that update with each new model, you have to be sure that you have a program that won’t let you down.

Also, it’s not enough to just have OBD2 scanning capabilities. Many new vehicles have ECU computer systems, which allow you to monitor the performance aspects of your car.

Fortunately, TOAD is the total package, meaning that no matter what make or model you have, you can find the code and diagnostic tool to fix any problem you encounter.On top of that, you can also “hack” your vehicle to perform better, meaning that you can do more with this single system.

Our Rating

Since we’re focusing on OBD2 scan software, most of the programs on this list won’t come with their own scanners. TOAD, however, does.

This makes it much easier to get started because you don’t have to worry about finding a scanner that is compatible with the system.

Also, many generic scanners can be less than high-quality, meaning that you may encounter issues when trying to diagnose a problem.

TOAD not only allows you to connect to your vehicle immediately, but it also has a Bluetooth option for wireless monitoring.

One issue with most OBD2 scanners is that they only work with the top makes and models. Thus, if you have a European or Asian vehicle that isn’t covered, you’re out of luck.

TOAD standard for Total Onboard Auto Diagnostics, and it’s not hyperbole. All cars, trucks, and SUVs around the world are included with this system.

To make it even better, you get free updates for life. Other software programs require annual renewals to stay current with codes, but TOAD has you covered forever. You’ll never miss out with this system.

If your car has an ECU system on board, then you can do even more with TOAD. This software allows you to make adjustments to your vehicle’s performance, all from your laptop.

You can study data in real time and see how your changes make it operate more smoothly. Whether you’re trying to get better gas mileage or you want to extend the life of your car, this capability can help you achieve those goals.

2. Palmer Performance PCMSCAN

As we mentioned, one issue with OBD2 software is that they may require you to buy separate scanning devices that might not be compatible.

Fortunately, if you get the PCMSCAN from Palmer Performance, you can buy a scanner so that you’re already good to go.

Our Rating

One thing that’s nice about this system is that it will work on both your computer or a mobile device. You can download the software onto your Apple or Android phone and diagnose remotely if necessary.

We highly recommend having this service on your computer as well, though, so you can read data and navigate through menus even faster.

If you’re worried about your older vehicle failing emissions tests, then you will love the fact that PCMSCAN allows you to run these tests in the comfort of your own garage.

You can monitor the data and see what’s happening in real time, which can help you make adjustments for a cleaner, more fuel-efficient ride.

With most OBD2 scanners, you have to be plugged in directly to the car to get a reading. With this system, you can access your vehicle remotely.

Best of all, you can buy a scanner that can stay in the vehicle at all times, enabling you to check up on it whenever you like, even while you’re out in the field.

3. OBD Auto Doctor

In this case, you will have to buy a generic OBD2 scanner if you want to use this software. However, once you find something compatible, you can download this program wherever you want it to go, including your computer, tablet, or smartphone.

This is a relatively straightforward system that allows you to monitor many of your vehicle’s components in real time.

Our Rating

Compatible With Mac, PC, and Mobile

We like OBD2 scan software that works across devices, so it’s nice to know that you can deploy the OBD Auto Doctor on any computer or mobile phone.

Downloading and setting it up is a breeze, and as long as you have a scan tool, you should be ready to go in minutes.

For some auto enthusiasts, it’s enough to check the OBD2 codes whenever the check engine light comes on. However, if you want to make sure that your vehicle is operating in pristine condition, you need to run some tests.

OBD Auto Doctor allows you to check a variety of systems so that you can drive at peak performance. Best of all, you can save and compare this information to see how your car handles over time.

The onboard interface for this program is one of the simplest options we’ve found. In some cases, the layout can be a little confusing, particularly if you’ve never done this before.

However, almost anyone of any skill level should be able to get up and running in no time.

4. FORScan

One issue that you may come across when using an OBD2 scanner is that you may not have access to the proprietary codes listed by some auto manufacturers.

While most dtc codes are universal, some companies have their own systems, meaning that you need access to them if you want to be sure that you’re diagnosing the right problem.

If you have a Ford, Mazda, Lincoln or Mercury car, then FORscan is the best option for you. If you don’t, then you want to avoid this system because it won’t help with any other brands.

That being said, if you have one of these vehicles, let’s see how it works.

How can I use my laptop to diagnose my car

With the development of the technology, modern automobiles now are all equipped with an On-board Diagnostics system (OBD). There are two kinds of OBD. One is OBD-I, the other is OBD-II. As you can guess OBD-II is an improvement over OBD-I in both capability and standardization. It is an advanced management system that professionals and backyard mechanics can connect to via the diagnostic port. You can also use a computer or laptop instead of a handheld scanner; however, you will need a kit. Most laptop diagnostic software is more advanced than handheld scanners, offering the ability to monitor engine performance, as well as read trouble codes.
Things You’ll Need:Laptop OBD-II kit
Instructions
1. Purchase a laptop OBD-II interface kit. You can purchase these kits at many automotive parts stores; in addition, they are available online.
2. Insert the software installation disc. Follow the prompts to complete the installation. If the installation does not automatically begin, access ‘My Computer’ and double-click on the disc to start.
3. Connect the components to your laptop. Most kits contain a USB to serial adapter for laptops without serial ports. Once the device is attached to the laptop, connect the OBD-II diagnostic port cable.
4. Start the software program. Double-click on the desktop icon if the program did not automatically start. Get comfortable with the control interface.
5. Bring your laptop to your vehicle. Turn the ignition key to the ‘On’ position, but do not crank the engine. Connect the OBD-II scan cable from the laptop to the diagnostic port on your vehicle, usually located in the driver’s side foot well, below the steering well.
6. Click the ‘Scan’ button on the control interface, if required. View the engine codes and diagnostic information provided by the program.
Tips & Warnings
Not all programs have the same number of features. The basic program will read ‘Check-Engine’ codes. Upgraded programs may offer additional features, such as engine operation monitoring, horsepower and fuel economy. So make sure you get the right problem that you needed.

Best OBD2 Scanner Reviews – Our Top 10

1. TOAD – Total Auto Diagnostics

Image credit : Toad ( Total car diagnostics )

Kicking us off is TOAD, which stands for Total Onboard Auto Diagnostics. This is an all-in-one system that enables you to not only figure out what’s wrong with your car, but how to fix it as well.

Compared to other OBD2 scanners, this is a comprehensive diagnostic scan tool that works well for both professional mechanics and auto enthusiasts alike.

Product Highlights

Compatible With All Makes and Models

With many OBD2 scanners, you have to pay attention to all of the makes and models that are compatible with the software. In many cases, certain vehicle types are omitted, which means that you’ll be out of luck.

With this easy to use TOAD obd2 scanner, however, that’s not an issue. It works with every make and model out there, so you never have to worry about coming up short when trying to diagnose a problem.

Lifetime Updates

Another issue that an OBD2 scanner may face is that it can become obsolete over time. With every new make and model that comes out, auto manufacturers will update and change the codes in the system. Alternatively you can also check our full list of obd2 codes.

Thankfully, TOAD will always be relevant, thanks to the fact that you’ll get lifetime updates and access to new repair manuals. Simply put, you’ll only buy TOAD once, but you’ll use this best obd2 scanner forever.

ECU Adjustment

Modern cars use onboard computers to control all of the internal systems. However, in most cases, all you can do is check to see what the computer says about a particular issue.

With TOAD, though, you can actually fine-tune your vehicle’s performance through the ECU mainframe. Thus, if you want to improve things like fuel efficiency or engine output, you can make these adjustments through the software.

When you compare TOAD to other OBD2 scanners, it really is the Total Onboard Auto Diagnostic tool. It has so many more features than other models out there, and the fact that you get access to professional-grade materials means that it works for everyone.

With modern OBD2 scanners, you can check on multiple vehicle systems, all thanks to the onboard computer. Thus, checking things like brakes, airbags, and oil are not an issue.

Unfortunately, TOAD is limited to the engine, which limits your ability to diagnose or monitor all of your vehicle’s processes. Overall, it’s a great tool, but it’s not as versatile as other scanners.

2. Innova 3160g

For the most part, when looking at various scanners, you’ll notice that they are small, handheld devices. While you can get more intensive software packages like the TOAD above, many casual car enthusiasts prefer models like this one from Innova. Let’s see how well it works.

Product Highlights

Compact Design

If you’re not interested in being a hardcore “car guru,” then it doesn’t make sense to buy a complete OBD2 scanning system. While professional-grade models are helpful, they can be a little overwhelming for many people.

Thus, having a compact and easy to use obd2 scanner like this one can be much more beneficial. It allows you to reset lights and diagnose what’s going on underneath the hood, which is all an OBD2 scanner should do.

Reset Oil, ABS, and Other Lights

When these devices first came out, they were only designed to reset the “check engine” light. Fortunately, modern varieties like this one can go beyond the original intent.

With this obd2 scanner, you can reset all kinds of dashboard lights, from TPMS to airbags. Also, you can diagnose what’s wrong with your vehicle so that you know what your next step should be.

Works With Most Models

Although this obd2 scanner isn’t as comprehensive as TOAD, it should work with your vehicle. We suggest looking at the complete list of compatible makes and models just to be safe, but if you have a top brand, you shouldn’t have to worry.

The simplicity and ease of use of this model are excellent. We think that this scanner will work for most people, especially those who don’t need all of the extra bells and whistles of a professional, mechanic-ready tool.

While checking and clearing dashboard lights is the primary function of an OBD2 scanner, it’s nice when you can go above and beyond. Unfortunately, this scanner doesn’t do much else beyond simple diagnostics and light resets.

PROS

CONS

3. Bluedriver 

Usually, when working with an OBD2 scanner, you have to plug the scan tool into the car every time you want to use it. However, with an easy to use device like this, you can simply check your phone whenever you want to see what’s going on underneath the hood. It’s one of the most convenient devices you can find.

Product Highlights

Wireless Connection

You can connect to this obd2 scanner via Bluetooth. It syncs to your phone using the proprietary app, meaning that you can check on your vehicle whenever you see fit.

Compatible With iPhone and Android

Typically speaking, if an obd2 scanner syncs to your smartphone, it will usually only work with one provider. Fortunately, Bluedriver is compatible with both operating systems, meaning that everyone can enjoy the simplicity and convenience of this device.

Constant Monitoring

One of the primary benefits of this unit is that you can leave it plugged in at all times. Thus, you can check up on your vehicle no matter where you are. Since you already have your phone on you, it’s much more convenient than other models.

The app that comes with this scanner has a lot of diagnostic tools, and the fact that it can stay plugged in is a huge win in our book.

Depending on the age of your battery, you may walk out to a dead car because of this device. If you’re not planning on driving for a couple of days, we suggest that you unplug it. Also, the Bluetooth connection can be spotty in a few cases.

4. Autel Maxisys Elite Diagnostic Scanner

As we’ll see, Autel Maxisys is an excellent maker of high-quality OBD2 scanners. This unit, the Elite Diagnostic Scanner, is a professional-grade device that comes with a lot of added features. If you’re serious about maintaining your car, this is an excellent choice.

Product Highlights

ECU Coding and Programming

As we discussed with TOAD, being able to adjust your vehicle’s performance via the onboard computer is an awesome feature. While you should know what you’re doing before messing with these elements, it’s nice to see that you can improve your car without having to pay for upgrades.

Rugged Tablet

Some scanners are a handheld device, while others sync to your smartphone. Autel bridges the gap by giving you a proprietary tablet instead.

What sets this apart is that it comes with all of the scanning and diagnostic trouble apps pre-installed, meaning that you can start using it immediately. Also, the tablet is built for mechanic workshops, so it’s made to last.

Live Scanning and Data Recall

With many modern scanners, you can monitor your car’s performance in real-time. Using the apps, you can not only check on your vehicle’s systems, but you can track the data and chart it over time so that you can spot potential issues before they become real problems.

The Elite Diagnostic Tool is an excellent choice for anyone who really wants to get the most out of their car. With so many professional-grade features and a rugged system, it will serve you well for years to come.

The operating system for the tablet is not as high-quality as it would be if you bought something from a department store and downloaded the apps yourself. Also, while wireless syncing is possible, it may not always work right.

PROS

CONS

5. Autel Maxisys MS908

Although we would suggest the Elite Diagnostic Scanner, the MS908 is another excellent choice by Autel Maxisys. This company makes some of the best OBD2 scanners, so you can’t go wrong, no matter which one you choose. Let’s see what this unit has to offer.

Product Highlights

Live data Scanning

For the most part, one of the better functions of a modern obd2 code scanner is the ability to monitor your car’s systems in real-time. The reason this is such a useful feature is that it allows you to check on your vehicle and pinpoint any potential problems that may arise in the future.

As with the Elite version, you can track and chart this data over time for even easier monitoring and diagnostic trouble fixes.

Instant Updates

If you’re ever worried about your obd2 scanner becoming obsolete, you can worry no more with the MS908. It will sync to the internet automatically so that it’s always up to date.

80 Makes and Models

With so many brands and cars in its memory banks, you’re sure to find yours without any issues. It includes foreign and domestic makes and models, and it continually updates the codes so that they’re always accurate.

While this system isn’t as comprehensive as the Elite, it’s more than enough for most auto enthusiasts. We like that it’s easy to use and that it comes with a lot of diagnostic tools. It’s an excellent choice for anyone who wants to check their car.

As with other Autel products, the operating system can be a little buggy. Also, connecting wirelessly can have issues, so we highly recommend getting an analog connector as well.

PROS

CONS

6. BAFX Products Bluetooth Diagnostic OBDII Reader

We’ve already seen a wireless OBD2 scanner from Bluedriver, but this model from BAFX works about the same. However, the most significant difference is that it doesn’t come with its own mobile app, so you have to find one that works. However, that can be an advantage in most situations.

Product Highlights

Bluetooth Connection

Overall, being able to diagnose and monitor your car remotely is such a benefit. Thus, rather than having to find your code scanner, plug it in, and then wait for the data to come out, you’re always ready to go with your smartphone.

Compatible With All Makes and Models (Depending on the App You Choose)

Technically speaking, this will work on all OBD2 scanner compliant cars. However, since it doesn’t come with a proprietary app, the codes will be dependent on that. Thus, we suggest finding an app that has your make and model included.

Can Be Plugged In All the Time

Like with the Bluedriver model, you can keep this scanner connected. However, be sure to remove it if you’re not planning on driving for a while, as it will slowly draw power from the battery.

Overall, this is an excellent scan tool if you have a compatible third-party app. We like that it’s simple to set up and that it can stay plugged in at all times.

Syncing your app to this device can be tricky, and not all apps are compatible. Also, since it will slowly drain your battery, you do have to be aware of it and remove it if you’re not going to be driving for a couple of days.
