Warranty Enhancement Letter D0E Subject: Limited Service Campaign (LSC) D0E Certain 2012 – 2013 Model Year Tundra and Sequoia Vehicles ECM Software Update In our continuing efforts to ensure the best in customer satisfaction, Toyota is launching a Limited Service Campaign (LSC) on certain 2012 – 2013 MY Tundra and Sequoia vehicles. This LSC will cover approximately 19,000 Sequoia and 103,000 Tundra vehicles equipped with a 5.7 liter gasoline or 5.7 Liter-Flex Fuel engines. Background: In the vehicles covered by this LSC, the Engine Control Module (ECM) calibration may cause an emissions control component called an Air Injection Pump to fail in certain environmental conditions. If this occurs, the vehicle could enter a “Fail-Safe” Mode (also known as “Limp-Home” Mode). This mode reduces the vehicle’s power and speed, which could inconvenience an owner and require immediate repair. The Check Engine Light may come on with codes P0418 and/or P2445 set in the ECU. Limited Service Campaign (LSC) Remedy The ECM calibration has been updated to reduce the possibility of this condition occurring. Authorized Toyota dealer are requested to verify the vehicle’s ECM calibration and, if necessary, update the calibration software at NO CHARGE to the vehicle owner. If an Air Pump Assembly has failed, it will be replaced at NO CHARGE. This LSC will be available until May 31, 2016, and will only be available at an authorized Toyota Dealer.
