Why This Matters

Different scanner models have unique update processes and software. Using the wrong update can cause your scanner to malfunction.

Step 2: Visit the Manufacturer’s Official Website or App

Find the Support or Downloads Section

Go to the official website of your scanner’s brand. Look for sections named “Support,” “Downloads,” or “Software Updates.” Many brands now offer mobile apps that can update your scanner directly.

Beware of Third-Party Sites

Only download updates from official sources to avoid malware or corrupted files that could damage your device.

Step 3: Connect Your OBD2 Scanner to a Computer or Smartphone

Using USB Cable

Most scanners update via USB connection to a PC. Use the original cable to avoid connection issues.

Using Bluetooth or Wi-Fi

Some modern scanners update via Bluetooth or Wi-Fi through a smartphone app. Make sure your phone is paired and within range.

Step 4: Download and Install the Update Software

Install Any Required Update Managers

Some brands require you to install a special program on your computer. Follow the instructions carefully.

Download the Latest Firmware

Select your scanner model and download the latest firmware or software update file.

Step 5: Perform the Update

Run the Update Program

Open the update software on your PC or app on your smartphone. Follow on-screen prompts to upload the update to your OBD2 scanner.

Keep the Device Connected

• Close other programs: Free your computer’s resources to avoid slow downloads or crashes.
• Read update notes: Check what changes or fixes the update includes to understand improvements.
• Keep your vehicle off: Updates are done on the scanner, not the car, so keep the ignition off unless otherwise instructed.

Troubleshooting Common Update Issues

Update Fails or Freezes

Try restarting the update process. Make sure your internet connection is stable. If problems persist, use a different USB cable or update via a smartphone app if available.

Scanner Not Recognized by Computer

Check drivers or software required for the scanner. Reinstall drivers or restart your computer, then reconnect the scanner.
