Do all vehicles have on-board diagnostic systems?
All vehicles manufactured after January 1, 1996 are required to have OBD-II systems; although some manufacturers implemented OBD-II as early as 1994. OBD-II standards were originally developed by SAE and later adopted by the EPA and CARB (California Air Resources Board).
What is on-board and off board diagnostics?
How Vehicle Diagnostics Works? 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).
What type of OBD is my car?
The standard OBD2 interface is a 16-pin connector. OBD2 interfaces are the same, so if the interface has 16-pin connector, so your car is OBD2. If it looks different, your car is OBD1. The OBD interface is usually located somewhere on the dashboard of the car.
Where do you plug in a diagnostic tool?

How do I run a diagnostic test on my car?
Plug your car code reader into the diagnostic link connector under the dash (engine off). Then start the vehicle and follow the auto code reading procedure in the instruction manual. Nothing can knock your day off track faster than a “Check Engine” light popping up on your dash.
What is meant by on-board diagnostics?

What does a diagnostic test on a car tell you?
