This TSB was released by General Motors, covering most of their large SUV’s and vans that have been produced from 2002 and up. The related DTCs that a technician may find are P0420, Catalyst Efficiency Below Threshold, and/or P0430, which is the same thing, Catalyst Efficiency Below Threshold, just for bank 2. Technicians are seeing these codes on low mileage vehicles, or vehicles that have recently had the catalytic converter replaced.
