U0577Invalid Data Received From Lighting Driver Control Module D
- Generic OBD-II code · Network
- How the car detects it
- U0577 is the code for invalid messages from lighting driver control module D, the last of the four-letter block; U0276 is its lost-communication partner. LED matrix drivers can be chained: TI's TPS92662 addresses up to 31 devices over one multi-drop UART line, can use CAN transceivers for a sturdier physical layer, and also drives sequential turn signals and animated daytime lights. Lincoln documents four driver modules, A to D, for the headlamps of the 2025 Navigator without saying where each one sits. No manufacturer publishes U0577. Corrupt status from module D may disable dynamic functions it handles, while the lamp can keep burning in its default mode. No MIL.
