Cadillac Buick GM Reverse Radar Sensor 84903584 Parking Sensor

If your Cadillac or Buick experiences continuous beeping, no warning indicators, or rear radar false alarms (e.g., alerts with no obstacle behind), this usually indicates aging or damaged factory-rear parking radar probes. When functioning normally, they emit and receive ultrasonic signals to detect rear obstacles and provide proximity warnings to assist parking. Compatible GM-platform models include Cadillac ATS-L, XTS, CT6, and Buick Regal, LaCrosse, Enclave, and other GM vehicles. OEM number is 84903584. Installation requires disconnecting the vehicle battery first, ensure correct probe orientation (arrow marking up), and check that the wiring harness is clean and free of oxidation to prevent false alerts.
