1.1. What Are Auto Scan Codes?

Auto scan codes, technically known as Diagnostic Trouble Codes (DTCs), are alphanumeric codes generated by a vehicle’s onboard computer system to indicate a malfunction or issue. These codes are standardized across the automotive industry, ensuring consistency and ease of interpretation for mechanics and technicians. According to the Society of Automotive Engineers (SAE), the standardization of DTCs began with the implementation of OBD-II (On-Board Diagnostics II) in the mid-1990s, making vehicle diagnostics more accessible and efficient.

1.2. How Do Auto Scan Codes Work?

Auto scan codes are generated when the vehicle’s computer detects a problem with one of its systems or components. This detection is made possible by a network of sensors that constantly monitor various parameters, such as engine performance, emissions, and safety systems. When a sensor reading falls outside the normal range, the computer stores a corresponding DTC in its memory.

For instance, if the oxygen sensor in the exhaust system detects an abnormal level of oxygen, it will trigger a DTC related to the oxygen sensor circuit. Similarly, if the anti-lock braking system (ABS) detects a malfunction in one of the wheel speed sensors, it will generate a DTC specific to that sensor.
