Q: What does code U042D mean?

Invalid Data Received From Active Vibration Control Module. U042D means the module that coordinates the vehicle's active vibration control system sent data that other modules on the network judged invalid or implausible. The fault is set by a module that receives the corrupted or missing message, not necessarily by the vibration control module itself, so the root cause can be network communication, power supply, or the module's internal processing.
