What the filename identifies
The base catalog entry is 89663-60C03. The suffix MOD_E2 identifies this file as a modified variant, but it does not establish what was changed or what “E2” means in this record. It should not be interpreted as a specific emissions or drivability modification without supporting documentation.
An engine control module generally manages functions such as fuel delivery and ignition timing using sensor inputs. That general role does not establish the behavior of this particular file or its compatibility with a specific Toyota or Lexus vehicle.
