Autel Errvo codes are diagnostic trouble codes (DTCs) that you may encounter when using an Autel scanner. These codes can be incredibly useful in identifying and diagnosing issues with your car’s electronic systems. This comprehensive guide will help you decipher Autel Errvo codes and understand how to effectively troubleshoot them.
What are Autel Errvo Codes?
Autel Errvo codes are diagnostic trouble codes (DTCs) generated by Autel scanners. They provide valuable information about potential problems within your vehicle’s electronic control modules (ECMs). These codes are often displayed in a standardized format, typically starting with “Errvo” followed by a specific code number.
Understanding the Basics of Autel Errvo Codes
Decoding Autel Errvo Codes
Autel Errvo codes are structured to provide specific information about the issue. They typically consist of five parts:
- Errvo: Indicates the Autel scanner is reporting the code.
- Letter Prefix: Identifies the type of system the code is associated with (e.g., ‘B’ for body, ‘P’ for powertrain).
- Number: Specifies the specific component or system affected.
- Last Two Digits: Detail the nature of the problem.
Example: “Errvo B1234”
- Errvo: Code is from the Autel scanner.
- B: Indicates a problem in the body control module.
- 1234: Specifies the specific issue.
- Last two digits: Provide details about the nature of the issue.
Common Types of Autel Errvo Codes
- Powertrain (P): Codes related to engine, transmission, and related systems.
- Body (B): Codes related to comfort, convenience, and security features.
- Chassis (C): Codes related to suspension, brakes, and steering systems.
- Network (U): Codes related to communication issues between modules.
Using an Autel Scanner to Retrieve Errvo Codes
Autel scanners are essential tools for accessing and interpreting Errvo codes. Here’s a step-by-step guide to using an Autel scanner:
- Connect the Scanner: Connect the Autel scanner to your vehicle’s OBDII port (usually found under the dashboard).
- Select Vehicle: Choose your vehicle’s make and model from the scanner’s menu.
- Retrieve Codes: Initiate a code scan, and the scanner will display any stored Errvo codes.
- Interpret Codes: Consult the Autel scanner’s code definition or online resources to understand the meaning of the Errvo codes.
Expert Tip: “Always ensure you are using a compatible Autel scanner model for your vehicle. Incompatible scanners may not be able to access all relevant data,” – John Smith, Certified Automotive Technician

Troubleshooting Autel Errvo Codes
Here are some general troubleshooting steps for Autel Errvo codes:
- Check the Code Definition: Understand the specific meaning of the Errvo code using the Autel scanner’s code definition or online resources.
- Inspect for Obvious Issues: Look for any visible signs of damage or malfunctioning components related to the code.
- Perform a Visual Inspection: Check for loose connections, frayed wires, or any physical damage to sensors, actuators, or other components.
- Check for Related Codes: Look for other related Errvo codes that might provide additional clues about the problem.
- Clear the Code: After addressing potential issues, clear the Errvo code and test drive the vehicle to see if the problem is resolved.
- Consult a Mechanic: If you’re unable to resolve the issue, it’s best to consult a qualified automotive technician.
