Autel always pushes the latest updates when needed. However, sometimes users miss it because they don’t know how to update the tool. 

So, if you have an Autel diagnostic tool to keep your car in check, this may be the time to update it. But how do you update the tool? 

Previously, we explored the car problems an Autel scan tool can diagnose and discussed the effectiveness of integrating key programming tools with OBD systems. Today, we'll walk you through how to update an Autel diagnostic tool. 

Let us help you with a step-by-step guide to updating Autel scanner software and explain why these updates are important. 

Why Updates Matter

An outdated scan tool is a liability on the shop floor. Automotive diagnostic tools that are not up to date will throw communication errors or miss modules altogether, as manufacturers change protocols every model year. 

Anyone running an OBD2 scanner for car owners or a full-featured vehicle scanner in a workshop knows that staying up to date isn’t optional; it’s what keeps the tool useful.

What Do You Need to Confirm Before Updating the Autel Tool?

A few things to check first:

• Your device has 20% or more battery or is plugged in

• You’re on a good Wi-Fi connection (skip doing big downloads using mobile hotspots)

• You registered the tool using an Autel ID – compulsory for most update routes

• You know if you need a software update or a full Autel diagnostic tool firmware update (firmware updates the operating system, and software updates vehicle coverage and apps)

Step By Step: How to Update An Autel Diagnostic Tool 

There are 2 ways to do it: one via Wi-Fi and the other via a PC. 

Here is how to update using each:

Update Autel Diagnostic Tools Through Wi-fi. 

You can update the Autel MaxiCOM diagnostic tool through the following method:

1. Connect to wifi:

Open Settings > Wi-Fi, select a network, then enter the password. Use home or shop Wi-Fi, not a mobile hotspot – updates can run several gigs, and hotspots time out or throttle.

2. Sign in by Autel ID:

If you haven’t linked one yet, you’ll be asked to link one at this step. If you don’t have it, the Update app won’t pull new packages.

3. Open the Update app; it is a separate icon on the home screen and not one of the diagnostic apps:

You tap, and it checks with Autel’s servers and spits out a list of all available: vehicle software, firmware and any bundled apps.

4. Select what to install:

To grab everything, just tap Update All, or tap into the list and pick out specific vehicle makes or packages if you only want certain coverage and want to save space.

5. Allow it to download and install:

Each package is shown with a progress bar. You need to keep the tool plugged in or at least at 50% battery, and you can’t leave the app or lock your screen. Interrupting a firmware install mid-write can corrupt the firmware and require a factory reset.

6. Restart the tool:

Tap Restart after installation, or power cycle it manually if it doesn't prompt. The software will not load completely until after the reboot.

7. Update confirmed:

Launch the Update app again and confirm the version numbers are what you just installed, or check Settings > About to see the current firmware version.

Updating Through a Computer (Maxi PC Suite)

Use this path if your model doesn't support on-device updates, if a firmware file is too big to pull over Wi-Fi, or if the on-device Update app is stuck.

1. Download Maxi PC Suite: 

Search results can sometimes return outdated or third-party mirrors, and installing from elsewhere risks a corrupted installer.

2. Download it to your computer:

Run the installer and wait for it to complete. No special setup is required for a normal update.

3. Connect the scan tool via USB:

If possible, use the original cable; some third-party USB cables don’t have a strong enough data connection for big transfers, and the update will stall partway through.

4. PC Suite Log in with your Autel ID:

This is the same account you use on the device. Once connected, PC Suite automatically reads the tool's serial number.

5. Check for updates:

PC Suite lists firmware and vehicle software separately, and sometimes shows packages that the on-device app hasn't yet surfaced.

6. Click Update and leave it to run:

Do NOT disconnect the USB cable or close PC Suite while the progress bar is in motion.

7. Disconnect when it hits 100%:

Unplug the tool, turn it on (or restart if it was already on), and wait a minute for it to load the new software before opening any diagnostic app.

Tips for Successful Updates of the Autel Tool 

One can think that once you know the steps, it is all set to go for updates, but it is not. You must think of the following as well: 

1. Firmware vs. Software Updates

It's a common mix-up. Firmware manages the tool's core operating system and its communication with the hardware. On the other hand, software deals with vehicle-specific diagnostic protocols, special functions, and applications like ADAS system calibration modules. To ensure everything works smoothly, you need both to be up to date.

 If you have a tool with the latest firmware but outdated vehicle software, it won't be able to handle the latest models effectively. 

2. Check Compatibility Before Buying Add-ons

Autel diagnostic tool compatibility varies by model and region. For example, the best car diagnostic scan tool in 2026 - a MaxiCOM MK908 operates on different software packages compared to a basic MaxiDiag. Plus, the coverage for the diagnostic scan tool for Australian cars is not the same as that for US or European vehicles. 

So, before you assume that a new update or accessory will be compatible, make sure to check the model number against Autel's coverage list. 

3. Picking the Right Tool for the Job

Not every shop has the same needs when it comes to diagnostic tools. 

• If you are looking for the best Autel diagnostic tool for workshops, the MaxiSYS Ultra or the MS909 are excellent choices, offering full bidirectional control and ADAS capabilities. 

• If you need budget-Friendly OBD2 tools, consider the entry-level MaxiDiag or MaxiCOM models, which are perfect for basic code reading and resets. 

• Independent technicians searching for the top car diagnostic scan tool in 2026 should carefully consider the length of update support in relation to the price. 

Remember, a cheaper tool with limited update coverage can end up costing you more in the long run.

Regular updates help your Autel scan tool deliver accurate car diagnostics, reduce communication issues, and support newer vehicle models. 

Whether you update through Wi-Fi or Maxi PC Suite, following the correct process keeps your scanner operating at its best.
