Panic Alarm - Lights & Horn (2021+) is a lower-risk, convenience-oriented change for 2021–2026 Ford F-150 trucks, applied with FORScan over an OBD-II adapter. Sets the key-fob panic alarm to sound the horn as well as flash the lights. It is fully reversible and typically takes about 5 minutes to write once your worksheet is in hand.
The change touches the Body Control Module (BCM), and your F-Config worksheet lists all 2 as-built code rows with the module, address, and target value. Each row includes a blank for your original value so you can back up before writing changes and roll back later. Panic button gets attention instead of only flashing.
