Notes
Sheet field is Software ANC / Software ESE/EV-ESE (in-cabin sound). Forum users conflated it with the PowerBoost <20 mph exterior sound; that exterior pedestrian alert is a separate, legally required system and is NOT this mod. Changing this nibble may also affect active noise cancellation.
How to apply it
- Back up every module's As-Built data and keep the files somewhere safe.
- Connect FORScan with a battery maintainer on, ignition ON and engine OFF.
- Open Configuration and Programming, choose the ACM module, open As-Built Format and edit only the digit described by the source.
- Write, follow any module reset prompt, cycle the ignition, then confirm the feature and check for new trouble codes.
