Toyota and Lexus Firmware 342F9000.mod

342F9000.mod is a Toyota or Lexus automotive firmware catalog identifier. The available identifier alone does not reliably establish which control module it belongs to or what vehicle function its software controls.

The .mod filename identifies a cataloged file, but it does not by itself establish a particular modification, vehicle application, or software revision history. A matching calibration record or service bulletin is needed to identify its application.
