Lost Communication With Door Window Motor A
What it means
U0222 means the car has lost communication with door window motor A — the networked module that drives that power window. That window may stop working or lose its one-touch and anti-pinch features. It's a comfort fault and doesn't affect how the engine or brakes work.
Can I keep driving? Yes — only the affected power window is impacted; the car runs and drives normally.
