Service bulletin context
Toyota service bulletin T-SB-0170-09, released June 4, 2009, lists 30CA5200 as an updated calibration within its 2008–2009 Sequoia scope. A later record, T-TCI-3308, released November 13, 2009, also lists it as updated within a scope covering the 2008–2009 Sequoia and Tundra.
Those model lists describe the bulletins’ coverage, not confirmed fitment for every vehicle in that coverage. The records do not include the bulletin topics or the preceding calibration identifiers, so they do not establish a specific symptom, improvement or revision history for this file.
