U0275Lost Communication With Lighting Driver Control Module C
- Generic OBD-II code · Network
- How the car detects it
- Driver module C is the third LED driver unit a lamp controller can address. Three or more of them appear where each headlamp has several separately driven zones, as on the 2025 Lincoln Navigator, whose release notes name LDCMC alongside A, B and D. U0275 means the controller no longer receives C's messages; the reason may be the bus, the supply or the module. Driver controllers such as TI's TPS92682-Q1 have a limp-home pin that, when raised, makes them run on a separate set of preset values, so a lamp section can keep working without network commands. Neither U0275 nor the lamp section behind letter C is described in any public service text. Expect a lighting warning and lost adaptive features.
