OBDII U Code Definitions

Be sure to double check the codes.
Codes from U0000 to U1000 and U3000 to U4000 are Generic, defined by ISO/SAE.
Codes between U1000 and U3000 are Manufacturer specific and may not match the ones listed here. Check specific manufacturer pages on the site, as some of them, we list the OBD2 codes on those pages for those specific vehicles.
