Is OBDII consistent across the world?
Any vehicle sold in North America particularly in the United States must conform exactly to all OBDII rules.
What about vehicles that are sold in the US but also sold abroad? For instance imports such as BMW or Mercedes or US made cars that are exported. Do these vehicles continue to conform to OBDII outside of the US and north america?
What about vehicles that were never sold in north america such as Skoda or Citroen? Do these cars also conform to the exact letter of OBDII or is it a more loose implementation of OBDII or do they not use OBDII at all?
