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
Symptoms
- Lighting system warning in the instrument cluster
- Automatic high beam replaced by manual switching
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
