U0576 code meaning
Invalid Data Received From Lighting Driver Control Module C
What U0576 means
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.

Symptoms of U0576
- Lighting system warning in the instrument cluster
- Automatic high beam replaced by manual switching
Common causes of U0576
- PossibleDriver module C software fault, curable by an update
- PossibleUnstable supply or ground at the headlamp
- Less likelyLighting driver control module C internally faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0576 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 76 | The exact fault in that area. |
What to do next
- Note U0576 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0576
What does U0576 mean?
U0576 means "Invalid Data Received From Lighting Driver Control Module C". Lighting driver control module C is sending data that the receiver discards. It is a generic code, so it means the same on every make.
Is it safe to drive with U0576?
U0576 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0576 fail an emissions test?
U0576 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0576 to fix?
Difficulty: medium. A typical repair takes 0.3 to 3 hours of work. This is a job for a workshop.
Will U0576 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
