What does the on board diagnostic system do?
On-board diagnostics (OBD) refers to the automotive electronic system that provides vehicle self-diagnosis and reporting capabilities for repair technicians. An OBD gives technicians access to subsystem information for the purpose of performance monitoring and analyzing repair needs.
What is the difference between on board diagnostics and off board diagnostics?
While on-board vehicle diagnostics protocols like OBD/OBD2 are tasked primarily with emission related diagnosis, off-board vehicle diagnostics (UDS, KWP etc.) handle the diagnostics related to every other vehicle ECU (Electronic Control Unit).
How do I get my OBD monitor ready?
To determine if readiness OBD II monitors are complete:
- Turn the ignition key to the “on” position for 15 seconds without cranking the engine.
- If the “Service Engine Soon” light blinks eight times, one or more readiness monitors are incomplete.
