Car scanning and diagnostics is the process of using specialized equipment to diagnose and troubleshoot problems with a vehicle’s electronic systems. This can include anything from the engine control unit (ECU) to the transmission control module (TCM) and even the body control module (BCM). The process begins by connecting a diagnostic scanner to the vehicle’s onboard diagnostic (OBD) port, which is usually located under the dashboard.
Once connected, the scanner can read and display diagnostic trouble codes (DTCs) that indicate what system or component is malfunctioning. These codes can be used to pinpoint the specific problem and guide the technician in making repairs. In addition to reading codes, the scanner can also perform a variety of other tests, such as live data streaming, which allows the technician to see how different systems and components are performing in real-time. Car scanning and diagnostics can save time and money by helping to quickly and accurately identify problems with a vehicle, allowing for faster and more efficient repairs.
