U0576 Invalid Data Received From Lighting Driver Control Module C

Lighting driver control module C is sending data that the receiver discards. The US standard FMVSS 108 explains why this matters for an adaptive driving beam: the system must recognise malfunctions, including a blocked sensor, switch to manual beam control until the fault is gone and show the driver a warning. Driver chips like TI's TPS92664 keep failsafe default settings in internal memory, so a lamp still lights without fresh commands. Lincoln fits its 2025 Navigator headlamps with four such driver modules, lettered A to D. U0576 and partner U0275 appear in no public service text, and which lamp C serves is unknown. Expect a lighting warning and manual beam switching; no MIL.

Likely causes

Driver module C software fault, curable by an update
Unstable supply or ground at the headlamp
Lighting driver control module C internally faulty

Symptoms

  • Lighting system warning in the instrument cluster
  • Automatic high beam replaced by manual switching
