Malfunction indicator light and P261093
Toyota service bulletin T-SB-0013-19 lists 896650820000 as an updated calibration in a bulletin concerning the malfunction indicator light and diagnostic trouble code P261093. That code relates to the ECM’s internal engine-off timer performance. In practice, the warning light alerts the driver that the control system has detected a fault, while the stored code gives a technician a starting point for diagnosis.
The bulletin establishes this ID as an updated calibration for the documented issue. It does not establish that the calibration changes the engine’s normal power output or adds a driving feature.
Application in Toyota service records
Toyota also lists the calibration as an updated ECM calibration in T-SB-0001-18. That bulletin covers certain 2017–2018 Highlander and Sienna models. T-SB-0013-19 has a broader scope covering several Toyota models and model years. Those bulletin model lists describe the scope of each document, not confirmed compatibility between this calibration and every vehicle named.
The full identifier matters when distinguishing this record from other Toyota calibrations. A vehicle’s existing ECM identification and applicable service information are needed to establish whether a particular calibration applies.
