In late 2012 ? early 2013 Toyota announced a Limited Service Campaign (LSC C0D) for certain 2001 ? 2004 model year Toyota Sequoia vehicles currently registered in specific cold climate areas with high road salts usage (Cold Climate States*). Toyota is now announcing LSC CSD to also support owners of vehicles that are not registered in Cold Climate States that believe their vehicle has been or will be operated in cold climate regions where high road salt is frequently used and/or customers with concerns that their vehicle?s frame has more-than-normal corrosion.
