On-Board Diagnostics II
Definition
OBD-II is a standardised vehicle self-diagnostics port that exposes engine and system data, RPM, coolant temperature, fault codes, and more. Plug-and-play OBD devices read this data for tracking and diagnostics without hard-wiring.
OBD data turns a vehicle’s own sensors into a predictive-maintenance feed, letting fleets catch engine faults before they cause a roadside breakdown.
