U0574Invalid Data Received From Lighting Driver Control Module A
- Generic OBD-II code · Network
- How the car detects it
- Lighting driver control modules switch and dim individual LEDs or LED segments in modern headlamps. Lincoln's 2025 Navigator has four of them, labelled A to D, and an over-the-air release (25.10.08) for all four adjusted headlamp colour and brightness at start-up; NHTSA's summary adds an intermittent resistance fault that dropped the lamps to their lowest setting. U0574 is set when a receiver gets module A's frames but rejects the data. No maker publishes U0574 itself or partner U0273. LED matrix drivers such as TI's TPS92662 report open or shorted LEDs over a serial line, so a corrupt status message can stop adaptive light although the lamp still works. U0542 concerns headlamp control module A. No MIL.
