Hi everyone, I accidentally messed up my BCMii configuration in FORScan while attempting to enable cornering lights using text mode. My driver-side DRL (“eyebrow” LED strip) stopped working on ignition. \*\*Current Symptoms:\*\*Left DRL strip is completely OFF when ignition is ON or engine is running. Left DRL strip lights up/dims correctly during welcome lights when unlocking (so the LED unit itself is physically fine). DTC **B1087:00-C8** (LIN Bus A communication / configuration fault) present in FORScan._“Check Adaptive Headlamps”_ error message displayed on the IPC. Unfortunately, I didn’t save a backup beforehand, and I cannot download the As-Built file directly from Motorcraft due to account restrictions. **Vehicle Specs:Model:** 2017 Ford Mondeo Mk5 2.0 TDCi (EU) **Headlights:** Ford Dynamic LED **VIN:** WF0FXXWPCFGK54259 Could anyone with PTS / UCDS access please download and share the factory As-Built file (`.ab` / `.abt`) for my VIN? Alternatively, if you know the exact As-Built hex lines in BCMii/HCM needed to fix the LIN communication mask and restore the LED DRL configuration, I’d greatly appreciate your assistance! Thanks in advance! ---

You dont need the file. You can type it in manually. ---

> [@xxxdomin](#): > > but idk a fabric code You dont need this, has nothing to do with copying AB values. The hex code at the end is automaticlly calculated by Forscan. ---
