In previous articles, we explained how to upgrade our Autel scanners and whether to subscribe and update our Autel scanners annually. In addition to updating the Autel scanner, the accompanying Autel VCI also needs to be updated, otherwise VCI connection failures may occur.
Today we will mainly introduce why you need to update Autel VCI and how to update Autel VCI. Let’s take a look!
VCI is the abbreviation of Vehicle Communication Interface, which is the core hardware module for data communication between diagnostic equipment and the car. The VCI acts as a professional "translator" and "communications specialist," responsible for two-way communication between diagnostic equipment and the vehicle's internal network.
It "translates" software commands into protocol signals understood by the vehicle and securely and accurately transmits them to various control units (such as the ECU). It also transmits critical information, such as fault codes and data streams, back to the diagnostic equipment, forming an indispensable bridge for vehicle diagnosis.
The usage method of Autel VCI
Autel scanners vary in their VCI configurations, but the Autel MaxiVCI V200, Autel MaxiVCI Mini, and Autel Maxiflash VCI J2534 all offer the aforementioned features, providing a wider range of protocols and more convenient wireless connectivity for vehicle diagnostics. However, you'll need to regularly update the Autel VCI to keep it up to date.
Automakers release new models and update their electronic control units (ECUs) every year. Updating your VCI firmware ensures your device can communicate with and correctly identify the computers in these new vehicles, avoiding "model not supported" or connection failure issues.
No software or firmware is perfect. Updates often include fixes for known bugs, resolving issues such as tool freezes, communication interruptions, or sudden failures during critical diagnostic programming, significantly improving reliability and success rates.
Upgrade VCI to support the latest communication protocols.
Updates often introduce new diagnostic features, such as specialized testing, pairing, or programming for specific systems (e.g., battery management and advanced driver assistance systems). Existing features (e.g., key pairing and ECU coding) are also optimized to be faster, more stable, and more powerful.
Stable and secure communication is essential when programming or coding a vehicle. VCI firmware updates optimize its communication protocol handling capabilities with vehicle networks, ensuring accurate and secure data transmission and preventing the risk of vehicle "bricking" due to communication errors during ECU flashing.
Simply put, without VCI updates, your Autel diagnostic tool may be unable to diagnose new vehicles, its functionality may be outdated, and the risk of failures during critical tasks may increase. Regular updates are a fundamental investment in maintaining your professional diagnostic capabilities.
An outdated VCI cannot communicate with newer vehicles.
There are many Autel VCI models. The following steps take the upgrade of Autel MaxiVCI V200 as an example. The upgrade steps for other Autel VCIs are basically the same. You can refer to the upgrade steps below.
You'll find a USB port on the VCI. Use the included USB cable to connect the Autel scanner to the VCI firmware. During the update, make sure the Autel scanner is fully charged, either by plugging it in or charging it in advance.
When upgrading Autel VCI, ensure that your WiFi network is properly connected. Go to System Settings, select WiFi, and choose a stable and fast WiFi network to connect to. This will ensure that subsequent upgrades can proceed normally.
Click the VCI icon at the bottom of the Autel scanner, then click VCI Update on the left side of the screen. If an update is available, an Update Now button will appear on the right. Click it to proceed. Be sure to stay in the update screen during the process; it will take approximately 3-5 minutes.
Update Autel VCI now
After the update process is complete, unplug the data cable from the VCI and plug it back in.
Remove the data cable, make sure the VCI is connected to the Autel scanner via Bluetooth, plug the VCI into the car's OBD II port, and check if it shows a normal connection.
You can refer to the video below for operation:
As an important component of the auto diagnostic tool, Autel VCI plays a vital role in vehicle diagnosis. Regularly check if Autel VCI needs to be upgraded, and follow the steps above to complete the upgrade so that it can perform better.
