25 distinct codes across 28 real Hyundai diagnostics.
25 distinct codes across 28 real diagnostics on Hyundai, including the Hyundai-specific ones no generic code list can decode.
Hyundai-specific codes
These are manufacturer-specific, which means the same code on another marque is a different fault. That is exactly why they have no page of their own and no entry in any generic code list. Scoped to Hyundai and ranked by how often we have actually seen them, they are a claim we can stand behind.
