Code B0959 Pontiac Description

The parking assist sensors are 3-wire ultrasonic sensors that are used to determine the distance between the vehicle and an object. The Parking Assist Control Module supplies 12 V to the parking assist sensors via the 12 V reference circuit and provides ground via the low reference circuit. The Parking Assist Control Module triggers the sensors in a sequential loop. After each sensor transmits, the Parking Assist Control Module uses the sensor echo received through the signal circuit to calculate the distance and position of an object. The Diagnostic Trouble Code (DTC) will be set when the Parking Aid Rear Sensor signal to the Parking Assist Control Module is out of specification.
