1. Understanding OBD Codes vs. Manufacturer Codes
OBD (On-Board Diagnostics) codes are standardized diagnostic trouble codes (DTCs) used across all vehicle makes and models to indicate general emission-related issues. Manufacturer-specific codes, on the other hand, are enhanced DTCs that provide a more detailed and precise diagnosis of a specific vehicle’s systems and components.
| Feature | OBD Codes | Manufacturer Codes |
|---|---|---|
| Standardization | Standardized across vehicles | Unique to each manufacturer |
| Detail Level | Basic emission issues | Specific system and component issues |
| Data Provided | Limited | Extensive |
| Usefulness | Quick overview | Precise diagnostics |
| Example | P0171 (System Too Lean) | B1000 (Airbag System Fault) |
2. Why Your Autel MaxiSys Might Only Show OBD Codes
Several reasons can cause your Autel MaxiSys to display only OBD codes instead of the more detailed manufacturer-specific codes:
- Incorrect Vehicle Selection: Selecting the wrong vehicle year, make, or model can prevent the scanner from accessing the manufacturer’s diagnostic database.
- Software Issues: Outdated or corrupted software can limit the scanner’s ability to read enhanced codes.
- Communication Problems: Issues with the vehicle’s communication protocols or the scanner’s interface can result in generic code retrieval.
- Limited Diagnostic Support: Some older or lower-end Autel MaxiSys models may have limited support for certain manufacturer-specific codes.
- Subscription Status: An expired software subscription can restrict access to the latest manufacturer updates and diagnostic capabilities.

14. Understanding Diagnostic Trouble Codes (DTCs)
Diagnostic Trouble Codes (DTCs) are codes stored in a vehicle’s computer system when a problem is detected. These codes provide valuable information about the nature and location of the issue, helping technicians diagnose and repair the vehicle effectively. Here’s a breakdown of DTCs:
- Types of DTCs:
- Powertrain Codes (P): Relate to the engine, transmission, and associated components.
- Chassis Codes (C): Relate to the braking system, suspension, and steering.
- Body Codes (B): Relate to the body control systems, such as airbags, lighting, and power windows.
- Network Codes (U): Relate to the communication network between different ECUs.
- Structure of DTCs:
- The first character indicates the system (P, C, B, or U).
- The second character indicates whether the code is generic (0) or manufacturer-specific (1).
- The third character indicates the subsystem (e.g., fuel system, ignition system).
- The fourth and fifth characters provide a specific fault code.
- Reading and Interpreting DTCs:
- Use a diagnostic scanner like the Autel MaxiSys to read the DTCs stored in the vehicle’s computer.
- Consult a service manual or online database to interpret the meaning of each code.
- Follow the diagnostic procedures outlined in the service manual to identify the root cause of the issue.
- Clearing DTCs:
- After repairing the issue, clear the DTCs from the vehicle’s computer using the diagnostic scanner.
