U0276Lost Communication With Lighting Driver Control Module D
- Generic OBD-II code · Network
- How the car detects it
- U0276 closes the four-letter block: the controlling module has lost contact with lighting driver control module D. Lincoln names an LDCMD on the 2025 Navigator and updated it in the same over-the-air package as A to C; nothing more about its location is public, and no manufacturer documents U0276. Why a silent driver must not leave the driver in the dark follows from the US lighting standard FMVSS 108: a failure of automatic beam control may not take away manual low and high beam, and an adaptive driving beam must detect its own malfunctions and fall back to manual operation. A fault in module D should therefore cost comfort functions, not basic headlamp light. No MIL.
