U05BDInvalid Data Received From Localization and Mapping Module
- Generic OBD-II code · Network
- How the car detects it
- Hands-free and highly automated driving needs to know the car's position to lane level and the road ahead from a detailed map. GM handles this in a separate map module (K179) for Super Cruise: it holds a LiDAR-surveyed map that decides where the system may be engaged and receives map and GPS correction data over the air while driving. Bulletin PIT6000 (2021-2023 Escalade, Tahoe, Silverado and others) traces a Service Driver Assist message with B2BA1 to a map that stayed outdated after mostly short trips; on the 2022 Bolt EUV map files were updated by USB (N222360520). Bosch combines satellite positioning with correction data, inertial and wheel-speed signals. No manufacturer documents U05BD; it would flag invalid position or map data, U02BC a missing module.
