Highlander service record context
Toyota bulletin T-TCI-2656 lists 899834810300 as an updated calibration for the 2006 Highlander Hybrid. Later records, including EG030-07, list it as a previous calibration in bulletins covering the 2006 and 2007 Highlander Hybrid. That means a later revision was discussed in those bulletins, not that this calibration itself introduced the later change.
A separate T-TCI-2777 record lists the same full calibration as previous in a bulletin covering 2006 and 2007 Highlander models. Bulletin vehicle lists describe their scope and do not establish exact fitment for every calibration listed.
