Pending, confirmed and permanent codes
A pending code can reflect an initial failed monitor; a confirmed code has met the module's confirmation criteria. Where supported, permanent emissions codes normally clear after the vehicle's monitor verifies the repair, not simply with an erase command. Conditions differ by vehicle and jurisdiction. A stored code alone does not prove the fault is active now.
