Notes
Edits the power-steering module (safety-critical). Reported unreliable / not working on 2024-2026 by multiple owners; one 2026 owner's IPC change held only days. Fuel-economy strategy change; dealer updates may revert. Many owners prefer a plug-in eliminator.
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 PSCM 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.
