Diagnostic Trouble Codes (DTCs) are alphanumeric codes generated by a vehicle’s onboard computer system to indicate malfunctions or issues within various systems. According to the Society of Automotive Engineers (SAE), these codes are standardized across all OBD2-compliant vehicles, ensuring consistent diagnostic information. DTCs help identify the source of a problem, whether it’s related to the engine, transmission, emissions, or other systems. Each code consists of a letter followed by four numbers, providing specific details about the nature and location of the fault. By reading and interpreting DTCs, car owners and technicians can quickly diagnose issues and perform the necessary repairs.
2.2. Structure of an Actron OBD2 Pocket Scanner Code
An Actron OBD2 Pocket Scanner code, like all standard DTCs, follows a specific structure:
- First Character (Letter):
- P: Powertrain (engine, transmission)
- C: Chassis (braking, suspension)
- B: Body (interior, exterior)
- U: Network (communication)
- Second Character (Number):
- 0: Standard (SAE) code
- 1, 2, 3: Manufacturer-specific code
- Third Character (Number): Indicates the specific system or subsystem related to the fault.
- Fourth and Fifth Characters (Numbers): Provide further detail about the specific fault within the identified system.
For example, a code like P0300 indicates a standard powertrain code (P0) related to a random or multiple cylinder misfire (300).
2.3. Categories of OBD2 Codes
OBD2 codes are categorized into four main groups:
- Powertrain (P Codes): These codes relate to the engine and transmission systems. Examples include P0300 (Random Misfire Detected) and P0171 (System Too Lean, Bank 1).
- Chassis (C Codes): Chassis codes pertain to issues with the vehicle’s chassis and related components, such as braking and suspension systems. Examples include C0031 (Right Front Wheel Speed Sensor Circuit Range/Performance) and C0265 (ABS Activation Relay Circuit).
- Body (B Codes): Body codes involve problems with various interior and exterior components, such as airbags and climate control systems. Examples include B1001 (Electronic Control Unit (ECU) Internal Failure) and B0090 (Seat Weight Sensor Calibration Fault).
- Network (U Codes): Network codes indicate communication issues between different vehicle systems. Examples include U0100 (Lost Communication with ECM/PCM) and U0155 (Lost Communication with Instrument Panel Cluster (IPC) Control Module).
