Toyota 30CD0100.cuw Firmware: Sequoia and Tundra Calibration
A catalog reference for Toyota calibration 30CD0100.cuw and its appearance as an updated calibration in two service bulletins.
30CD0100.cuw is a Toyota calibration file identified as an updated calibration in two 2009 service records. The records connect calibration ID 30CD0100 with the 2008–2009 Toyota Sequoia and, in one bulletin, the 2008–2009 Tundra.
Service bulletin context
Toyota bulletin T-SB-0170-09 lists 30CD0100 as an updated calibration within a bulletin covering the 2008 and 2009 Sequoia. Canadian bulletin T-TCI-3308 also lists it as an updated calibration and covers the 2008 and 2009 Sequoia and Tundra. Those vehicle lists describe the scope of each bulletin rather than confirming that the calibration applies to every listed vehicle.
The available records do not identify the controller or the condition addressed by either bulletin. The exact vehicle system and operational change associated with this calibration therefore cannot be established from the catalog and bulletin details alone.
