Toyota and Lexus Firmware 89983-30201
A catalog reference for Toyota and Lexus calibration identifier 89983-30201 and its control module family.
89983-30201 is a Toyota or Lexus electronic control calibration identifier in the 89983 part-number family. That family is associated with electronic control unit software, but the identifier alone does not reliably establish the exact controller or vehicle system for this entry.
It should be treated as a calibration reference rather than a confirmed vehicle fitment or a description of a particular software change. The complete identifier can help distinguish this record from other calibrations with similar number prefixes.
