Encountering a “Current Mode Not Supported” error message on your Autel OBD2 code reader can be frustrating when you’re trying to diagnose your vehicle. This guide, brought to you by carparteu.com, will delve into understanding and troubleshooting this common issue, ensuring you get back to diagnosing and fixing your car efficiently. We’ll explore common causes and solutions, drawing upon Autel’s troubleshooting expertise to help you navigate this error.
Understanding the “Current Mode Not Supported” Message
When your Autel OBD2 scanner displays “Current Mode Not Supported,” it generally indicates a communication problem between the scanner and your vehicle’s computer (ECU). This doesn’t always mean your scanner is faulty, but rather there’s a mismatch or incompatibility in the communication process. Let’s break down potential reasons and solutions based on common Autel OBD2 reader issues.
Is Your Vehicle Truly OBD2 Compliant?
Before diving deeper, the first and most crucial check is to confirm your vehicle’s OBD2 compliance. While OBD2 has been a standard in the USA since 1996 and Europe since 2006, adoption timelines vary across regions.
- Europe: OBDII system adopted since 2006.
- U.S.A: OBDII system adopted since 1996.
- Asia: OBDII system adopted since 2009.
If your vehicle falls outside these adoption timelines for your region, it might not be fully OBD2 compliant, leading to the “Current Mode Not Supported” message. Also, be aware that EOBD (European On-Board Diagnostics) and JOBD (Japanese On-Board Diagnostics), while related, are not strictly identical to OBD2 and might cause compatibility issues.
Troubleshooting Step: Try connecting your Autel scanner to another vehicle that you know is OBD2 compliant, preferably a US vehicle like a Ford, GM, or Chrysler. If the scanner works correctly with other vehicles, the issue likely lies with the original vehicle’s OBD2 compliance.
Communication and Connection Issues
A fundamental aspect of OBD2 scanning is a stable and correct physical connection. Communication errors can arise from simple issues like a faulty OBD2 cable or a poor connection.
Troubleshooting Steps:
- Inspect the OBD2 Cable: Check your OBD2 cable for any visible damage, such as frayed wires or bent pins. A damaged cable can disrupt communication.
- Secure Connection: Ensure the OBD2 connector is firmly plugged into your vehicle’s OBD2 port. A loose connection can cause intermittent or failed communication.
- Try Another Cable: If possible, test with a different OBD2 cable to rule out a cable malfunction.
Software Glitches and Authorization Errors
Sometimes, the “Current Mode Not Supported” message might be misleading, masking underlying software or authorization issues within your Autel device.
Troubleshooting Steps Based on Related Autel Errors:
-
“Authorization Check Failed” Errors: Autel scanners require software authorization. Errors like “Authorization Check Failed! Error Code: 1/2/3/4/5/8/9/10” can sometimes manifest as communication problems. If you suspect this, refer to your Autel device’s troubleshooting for authorization errors. This often involves:
- Checking for “authorization.txt” files in your device’s file system (using ES File Explorer if available).
- Renewing your software subscription if it has expired.
- Reinstalling software updates.
- Contacting Autel tech support with your device’s serial number.

-
Software Update Issues: Outdated or corrupted software can lead to various errors, including communication problems.
- Check for Updates: Ensure your Autel software is up to date. Navigate to the update section of your device and check for any pending updates.
- Clear Cache: Sometimes, clearing the app cache can resolve software glitches.
- Android: Long hold the app icon, go to app info > storage > Clear cache.
- iOS: Go to Me > Settings > Clear Cache.
- Reinstall Software: In more severe cases, uninstalling and reinstalling the Autel software might be necessary.
-
“Acquire Failed” Login Errors: If you’re experiencing login issues with messages like “Acquire Failed,” this could indirectly affect scanner functionality and potentially contribute to communication errors. Ensure you are logged in correctly and, if needed, try downloading the MaxiAP200 app to your device as suggested by Autel’s troubleshooting.

Vehicle-Specific Issues
In some instances, the problem might not be with your Autel scanner but with the vehicle itself.
Troubleshooting Steps:
- Check Vehicle’s OBD2 Port: Inspect your vehicle’s OBD2 port for any damage or corrosion.
- Vehicle’s Electrical System: Problems within the vehicle’s electrical system, such as a faulty ECU or wiring issues, can prevent communication with any OBD2 scanner. Consult a qualified mechanic to check for underlying vehicle issues if you suspect this.
- Module Communication Errors: If you are receiving communication errors with specific modules (e.g., engine module, transmission module) but other modules communicate fine, there might be an issue specific to that module or its wiring.
