OBD2 codes, those cryptic messages your car throws at you, can be confusing. But with an Autel OBD2 scanner, deciphering these codes becomes a manageable task. This guide dives deep into the world of Autel OBD2 codes, empowering you to understand your car’s health better.
What are Autel OBD2 Codes?
A standardized system across vehicles manufactured since 1996, OBD2 codes, or On-Board Diagnostics codes, are your car’s way of communicating malfunctions. When your car’s computer detects an issue within the engine, transmission, emissions system, or other critical components, it generates a specific code. This code is then stored in the vehicle’s computer and can be retrieved using an OBD2 scanner, like those offered by Autel.
Autel, a leading name in automotive diagnostic tools, provides a range of OBD2 scanners catering to everyone from car enthusiasts to professional mechanics. These scanners act as the bridge between your car’s complex computer system and your understanding, translating those confusing codes into actionable information.
Deciphering the Code: Types of Autel OBD2 Codes
Autel OBD2 codes aren’t random. They follow a specific structure, making it easier to pinpoint the problem area. Understanding this structure can give you a head start in diagnosis:
-
The First Character: This letter indicates the system where the fault originates:
- P: Powertrain (engine, transmission, emissions)
- B: Body (airbags, power seats, etc.)
- C: Chassis (ABS, traction control, etc.)
- U: Network & Communication (modules, wiring, etc.)
-
The Second Character: This number specifies whether the code is generic (applicable to all OBD2 compliant vehicles) or manufacturer-specific:
- 0: Generic (SAE – Society of Automotive Engineers)
- 1: Enhanced (Manufacturer Specific)
-
The Third Character: This number points to the specific system or sub-system affected:
- 1: Fuel and Air Metering
- 2: Fuel and Air Metering (Injector Circuit)
- 3: Ignition System or Misfire
- 4: Auxiliary Emissions Controls
- 5: Vehicle Speed Control and Idle Control System
- 6: Computer Output Circuit
- 7: Transmission
- 8: Transmission
- 9: SAE Reserved
-
The Final Two Characters: These numbers represent the specific fault within the identified system.

Common Autel OBD2 Codes and Their Meanings
While an Autel scanner will provide specific code definitions, here are some commonly encountered codes and their general meanings:
- P0411: This code indicates a problem with the secondary air injection system, which reduces emissions during cold starts.
- P0171: This code suggests the engine is running lean, meaning there’s too much air or not enough fuel in the air-fuel mixture.
- P0300: This code points to random misfires in one or more cylinders, often caused by faulty spark plugs, ignition coils, or fuel injectors.
- P0420: This code indicates a problem with the catalytic converter’s efficiency, suggesting it’s not effectively converting harmful exhaust gases.
- U0100: This code signifies a loss of communication with the Engine Control Module (ECM), potentially due to wiring issues or a faulty ECM.

Beyond Code Reading: Troubleshooting with Autel
Autel scanners equip you with more than just code interpretations. They empower you to delve deeper into the issues:
- Live Data Stream: Access real-time information from various sensors in your car, like engine RPM, coolant temperature, oxygen sensor readings, and more. This data can help pinpoint the root cause of a problem.
- Freeze Frame Data: When a fault occurs, the car’s computer stores a snapshot of various parameters at that specific moment. This “freeze frame” data can be invaluable in diagnosing intermittent issues.
- Component Activation: Some Autel scanners allow you to activate specific components, like fuel injectors or solenoids, to test their functionality directly.
