U0560Invalid Data Received From Electronic Brake Booster Control Module B
- Generic OBD-II code · Network
- Can trigger limp mode
- How the car detects it
- A second brake booster unit mainly appears in architectures built for automated driving, where a single electronic brake must not be a single point of failure. Bosch, for example, pairs its integrated power brake with a separate redundant brake unit that can stop the car if the primary unit fails. U0560 reports that the module labelled B sends data the receiver cannot use, for instance a status that contradicts the A unit or a frame with a wrong counter or checksum. No manufacturer documents U0560 publicly, and which physical unit carries the B label depends on the maker. U025F is the lost-communication counterpart. Losing redundancy usually triggers a warning and can disable assisted or automated driving functions.
