7 Best GM Scan Tools Review 2021 [Update]

Like many motorists in these difficult times, there is a fair chance that you are searching for ways to cut costs. DIY mechanics enjoy a renaissance thanks to technology improvements, including a vast array of OBD2 Scanners for all enthusiasts.

With almost 3 million new General Motors vehicles sold annually, there is a competitive market for GM specific scanning and diagnostic tools. These cover all Chevrolet, Buick, GMC, and Cadillac models.

Complete beginners, DIY mechanics, hobbyists, technicians, and pro mechanics all have different requirements. GM OBD2 scanners suit every level, and they are generally a compromise between cost and functionality. The trick is only to buy what you need at the best quality for your price range.

These days, almost anyone can save themselves an expensive and inconvenient trip to the mechanic and improve their fuel consumption. Whatever your level of expertise, I will take you on my journey by identifying the best GM scanner for each situation and giving you the benefit of my buying experience.

Buying Guide
Why Do I Need a GM Scanner?

Most GM owners want a combination of the most common OBD2 diagnostic functions. After connecting easily via Bluetooth, WiFi, or an ethernet cable, your device should automatically identify a problem once the check engine light comes on and clear the associated fault.

This tool is a real cost-saver compared to the expense and hassle of trusting your car to a repair shop. Apart from the satisfaction of fixing your vehicle, OBD2 scanning technology puts you back in control.

Most users require essential functions for testing their vehicle’s emissions before it fails a costly smog test. Hobbyists want options for fine-tuning ignition timing, fuel consumption, and overall efficiency. Diagnostics experts and pro mechanics demand a full range of functions, including access to safety systems and advanced real-time diagnostics.

To know which type of buyer you are, ask yourself what functions you require and how much your budget is. It’s best not to pay for a top of the range, pro-GM scan tool if you never use most options. You can always upgrade once your knowledge becomes more advanced.

Best Professional Automotive Diagnostic Scanner Reviews

 

1. What are the differences between Autel Maxisys Elite and Autel Maxisys Pro (MS908P)?

You can see the Maxisys Elite as the upgraded version of the Maxisys Pro. They offer the same functions and vehicle coverage, but the improved components in the Maxisys Elite give it a longer battery life and faster processing speed. The Maxisys Elite is also compatible with USB 3.0 and can operate better in extreme temperatures.

2. What is difference between Launch X431 V and Launch X431 V+?

The X431 V+ has a larger screen that’s easier to read and navigate. It also uses a quad-core processor, compared to the dual-core processor in the Launch X431 V, and has a larger memory capacity, enabling it to perform diagnostic scans more quickly. While both units have on-board Bluetooth support and one-click update, the X431 V+ also has the option for wireless report printing.

3. Does Launch X431 V+ support super car like Ferrari, Maserati, or Lamborghini?

Some super-charged engines are supported, including Ferrari and Maserati. In addition to basic diagnostic functions, it supports service functions like clutch PID, gear learning, and throttle adaptation. Unfortunately, the Launch X431 V+ does not support Lamborghinis.

4. Can Launch X431 V+ relearn crank position and idle?

Yes, for most supported vehicles.

5. Why is the Launch X431 V+ not listed on Launch Tech USA website?

The Launch X431 V+ is sold exclusively in the United States through their authorized Amazon distributor and can’t be purchased directly from the company on their website. This is why you won’t see the product listed on that page.

6. Does the Autel MK808BT diagnose US made vehicles?

Yes, the Autel MK808BT is compatible with over 80 manufacturers, including vehicles made in the United States, Europe, and Asia.

7. Does Autel MK808BT comes with Bluetooth connection? Can it work without WI-FI?

The Autel MK808BT has Bluetooth support built-in. It also has the option of a wired connection so you can use it when there’s no Wi-Fi available.

8. Can Autel MK808BT relearn the idle?

No, the Autel MK808BT does not support that function. If you need the ability to relearn idle, you’ll want to look at the Maxisys Elite reviewed above.

9. What’s the difference between the Foxwell NT624 Elite and the NT614 Elite?

The main difference is that the Foxwell NT614 Elite is a 4-system diagnostic tool, able to read information from the engine, transmission, ABS, and SRS. The Foxwell NT624 Elite is an all-system diagnostic tool. It can read information from all electronic modules, including those listed above as well as things like the climate control.

10. Is theFoxwell NT624 Elite able to turn off a check engine code?

The NT624 Elite can clear the trouble codes that turn on the check engine light. If the check engine light comes back on after you’ve cleared these codes, theirs is likely an ongoing issue in the engine that needs to be fixed.

11. Will the Foxwell NT624 Elite show previous history codes?

Yes. The Foxwell NT624 Elite can read all codes, including permanent codes and previous history codes.

12. Will BlueDriver device display “short term and long term” fuel trim data?

Yes, you can view the fuel trim data under the Live Data section for most vehicles. You can check whether it’s compatible with your vehicle on the BlueDriver website.

13. Do you need an internet connection to use BlueDriver?

You can use many of the diagnostic functions of BlueDriver without an internet connection, including reading and clear codes, reviewing freeze frame data, running smog checks, and viewing live data.

More advanced features do require an internet connection. These include VIN decoding and repair reports, as well as retrieving service bulletins, recalls, and maintenance schedules. You’ll also need an internet connection to update the software or share reports.

14. Is BlueDriver compatible with all phones and tablets?

BlueDriver works with all iOS devices running operating system version 10.2 or later. It’s also compatible with Android devices running version 6.0 or later. Keep in mind you will need a Bluetooth connection to use your device with BlueDriver, something that may not be available on all Android tablets. The BlueDriver app is not currently compatible with Windows devices.

15. Which vehicles are compatible with BlueDriver?

BlueDriver can read engine codes from all consumer vehicles sold in the United States or Canada after 1996. Enhanced codes are available for many popular manufacturers, including BMW (2005 and later), Chrysler, Ford, GM, Honda, Hyundai (2011 and later), Mazda, Mercedes (2005 and later), Mitsubishi (2008 and later), Nissan, Subaru, Toyota, and Volkswagen.

BMW ICOM Next interface – problem

I have the same problem with ISTA-D
When try to connect to the control unit write me error: “The vehicle coult not be identified successfully. Check cehilce interface and ‘PAD active'”

The ICOM NEXT Interface is genuine and recognize 30KL and 15KL when have supply on PIN1 on the OBD connector.

I connect it on the car – the same fault…
I connect it a ECU on the bench – the same fault…

I attach you all pictures with contain important informaiton…

Could you pelase tell me what I can check more to fix this problem. Can I make test only on a controll unit on the bench with ICOM NEXT? How I can sellect manual the control unit or it must be recognized from the program?

Answer:

Direct, local, dhcp or static. Any of these options should work.
Yes, INPA will work with Icom Next. Install ‘standard tools’ from BMW. You have to ‘lock’ ICOM to use with INPA(at least I have to do it).  EasyConnect and EdiabasConfigurator are very helpful.
In my config I did setup static IP for Icom from my home network(10.0.11.x/24). That way I always know what IP it has in case I need to change something, ping if it’s alive etc.
For diagnostic(ISTA, INPA etc) I use direct connection(PC<–>ICOM). I assign IP manually to my PC from the same network as ICOM is in.
In some cases(flashing) you indeed need DHCP. You connect then your PC and ICOM to router. ICOM will keep it’s static IP(in my case something from 10.0.11.x/24), PC and car modules will get IP if needed from DHCP(still in the same network as your ICOM).
