U0560 indicates that the vehicle's control module received invalid data from the electronic brake booster control module B. This typically points to a communication problem between the brake booster module and the rest of the vehicle network.
The brake booster control module can develop internal faults that transmit erroneous data on the CAN network.
Corroded, broken, or loose wiring and connectors between the module and the vehicle network can cause data errors.
A fault on the CAN bus affecting multiple nodes can corrupt messages from the brake booster module.
PCM failures are uncommon; they usually only cause the code when the module misinterprets valid data.
In most cases, no; the issue is usually with the brake booster module, its wiring, or the CAN network, not the PCM.
Driving is generally safe for short distances, but reduced brake assist may affect stopping performance, so the problem should be addressed promptly.
A dedicated CAN bus analyzer can help identify network faults, but a standard OBD‑II scanner with live data often suffices for initial checks.
Typical replacement time is 1–2 hours, depending on vehicle design and access to the component.
