A catalog reference for Toyota and Lexus firmware identifier M-1374-A637A5A1AEED17DD9.tun.MOD and its modified-file label.
M-1374-A637A5A1AEED17DD9.tun.MOD is a modified firmware file identifier associated with a Toyota or Lexus catalog entry. The complete identifier does not reliably establish which control module or vehicle system it belongs to, or what the software controls.
Understanding the filename
The .tun.MOD ending labels this file as a modified variant. It does not, by itself, identify the changes made or establish how they affect vehicle operation. The identifier also does not establish a specific model, stock calibration or compatible replacement.
