IV. Background
In recent months, Toyota has received reports that some customers may experience a Malfunction Indicator Light (check engine light) "ON" condition
(P0420 or P0430). Toyota has investigated these concerns and discovered an issue with the program logic in the Engine Control Module (ECM). New
program logic has been developed to correct this condition.
