Service-record context
Toyota service bulletin EG030-07 lists 899834809100 as a previous calibration within its 2006–2007 Highlander HV scope. T-TCI-2656 also lists it as a previous calibration in a 2006 Highlander HV record. T-TCI-2777 lists the same full identifier in a 2006–2007 Highlander record.
These entries establish a Highlander service association for the calibration.
