通用PDC停车传感器 84575219 别克凯迪拉克雪佛兰GMC倒车雷达原厂替换

When your vehicle reverses and the radar system frequently misreports, has no response, or emits a continuous long alarm, this typically indicates the PDC parking sensor is aging or internal components are damaged. Under normal operation the sensor uses ultrasonic waves to accurately detect rear obstacles and raises graded alarm prompts to assist safe parking. This product is a genuine replacement; fits OEM numbers 84575219 and 0263063129 and is compatible with Buick, Cadillac, Chevrolet, GMC and various general models. During installation, ensure sensor interface is clean and free of rust, and strictly align with the vehicle’s wiring harness to avoid reverse insertion causing signal anomalies.
