A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

This SSC covers certain 2012 ? 2014 MY Tundra and Sequoia vehicles. This SSC will cover approximately 39,000 Sequoia and 247,000 Tundra vehicles equipped with a 5.7 liter gasoline or 5.7 Liter\-Flex Fuel engines. In certain 2012 ? 2014 Model Year Toyota Tundra and Sequoia vehicles equipped with a 5.7 Liter gasoline or 5.7 Liter\-Flex Fuel engines, the Engine Control Module \(ECM\) may set a Diagnostic Trouble Code \(DTC\) if debris/ice becomes lodged in the air switching valve. If this occurs, the Malfunction Indicator \(Check Engine\) Light could illuminate and the vehicle could enter a ?Fail\-Safe? Mode \(also known as ?Limp\-Home? Mode\). If this occurs the vehicle?s power and speed will be reduced, which could inconvenience you and require immediate repair.

TT: Greenhouse Gas Logic \(GHC\) has been implemented on Toyota A/C Systems to reduce tailpipe emissions. The federal government issues café \(Corporate Average Fuel Economy\) credits to vehicle manufacturers that implement new technologies that reduce the carbon footprint of the vehicles they produce. GHC Logic technology works by automatically operating the HVAC system in REC mode when certain operating conditions are met, improving the A/C systems cooling efficiency and reducing the vehicle's C02 emissions.
