DRL - Turn Signals Only (Halogen/Aftermarket) is a lower-risk, convenience-oriented change for 2015–2020 Ford F-150 trucks, applied with FORScan over an OBD-II adapter. Sets daytime running lights to turn signals for halogen or aftermarket 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. Provides turn-signal DRL behavior for non-stock-LED lighting setups.
