Parking distance control (PDC) ultrasonic sensors use a 3-pin connector for power, ground, and a combined signal line that carries both the trigger pulse and the echo return to the PDC control module.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | VCC | 12V supply | PWR |
| 2 | Signal | Combined trigger and echo signal | BUS |
