Its exact vehicle application and the functions affected by this file are not established by the catalog identifiers alone.
What the filename identifies
The filename carries the full calibration-family identifier followed by A_MOD_E2. The MOD label indicates a modified variant, while E2 distinguishes it within the filename. Those labels do not establish what was changed or identify a specific emissions, engine or driving feature.
An engine control module generally uses sensor inputs to manage functions such as fuel delivery and ignition. That describes the controller family’s role, not a verified change made by this particular file.
