U0413
Invalid Data Received from Wheel Speed Sensor (Rear, Driver Side)
ABS receives implausible rear-driver wheel speed data. ESP and traction control are deactivated. Wheel-speed signals feed ABS, ESC, traction control, transmission and odometer — a single dropped signal disables all of these safety functions until repaired.
