Code B0955 2015 GMC Sierra Description

The object sensors are 3-wire sensors that are used to determine the distance between the vehicle and an object of interest. The Parking Assist Control Module supplies 8 V to the object sensors via the 8 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 Front Sensor signal to the Parking Assist Control Module is out of specification.
