Park assist sensors are part of the park assist system, just one of many advanced driver assistance systems (ADAS) found on vehicles today. Damaged sensors are typically replaced and may require painting to match the vehicle. Vehicle makers often provide information on the painting of new sensors. Some vehicle makers do not recommend refinishing sensors with minor finish damage because excessive paint thickness may adversely affect the operation of the park assist system. However, other vehicle makers allow refinishing and provide guidelines. Let’s see what Subaru has to say.
Subaru offers Reverse Automatic Braking (RAB) on some models. This feature utilizes sonar sensors that are mounted in the rear bumper. Subaru states in the Technician Reference Booklet Vehicle Dynamics and Driver Assist Systems:
"On some models, the Sonar Sensors are painted to match the body color. In those instances, replacement sensors are ordered pre-painted to match the vehicle."
Subaru states within vehicle-specific service manuals under: Body & Electrical/Wiring system ➤Reverse Automatic Braking ➤ Sensor and Harness ➤ Removal:
"Caution: When reusing the sensor, make sure to align the mark on the sensor and the bumper face ? rear or others, and surely return each sensor to the original position before removed."
It is important to always follow OEM procedures for repairs. Finding this information quickly and efficiently contribute to a complete, safe, and quality repair.
