OBD (On-Board Diagnostics)

On-Board Diagnostics (OBD) is a system in vehicles that monitors their engine and other vital components for proper functioning. It detects issues or malfunctions and records error codes that mechanics can read to identify problems accurately. OBD helps ensure vehicles run efficiently, meet emissions standards, and maintain safety. Modern systems can also provide real-time data and alerts to drivers via a diagnostic scanner or even smartphone apps. Overall, OBD acts as the vehicle's health monitor, promoting easier diagnostics and timely repairs.
