Your BMW is equipped with both front and rear parking sensors called Park Distance Control, or PDC. The upsweeping rear window line can be problematic when reversing, although rear parking sensors are standard on all models.
Q. Where is the backup sensor?
Back up sensors install in the rear bumper and have a speaker that changes beeps as your close in on an obstruction. Backup sensors are motion activated detectors that alert drivers and/or pedestrians, by beeping/chirping when objects are too close behind a particular vehicle in reverse.

The reverse sensing system (RSS) sounds a tone to warn the driver of obstacles near the rear bumper when R (Reverse) is selected and the vehicle is moving at speeds less than 3 mph (5 km/h). The system is not effective at speeds above 3 mph (5 km/h) and may not detect certain angular or moving objects.
Q. How do you check car sensors?
How to Test Automotive Oxygen Sensors
- Remove the sensor and check it for bad connections or exposed wires.
- Re-install the sensor and turn on the engine.
- Set the digital volt ohm meter to read millivolts.
- Switch the engine on again and observe the meter reading.
- Locate the vacuum port and open it to create a vacuum leak.
Q. Why are my car sensors not working?
There may be dirt and debris trapped on them or they may be oily or dusty. Make sure that you have it completely cleaned off before you put it back in. Then, turn on your car and see if there are any more issues arising after this has been done.
Q. How do I test a PDC module?
“You can check the sensors by engaging the PDC, and then passing your hand across in front of each sensor. They should click audibly. If no clicks from any of them, then its likely they are not being driven at all.” To check power at the module, its pin 7 on connector X300.
Q. What is a PDC module?
For some years now the PDC (Park Distance Control) system has been a standard feature of a car. When reversing sensors recognize obstacles behind the car, the board computer gives the driver an optical and/or acoustic signal. The PDC should really go haywire and permanently give warning signals.
Q. What is PDC in BMW?
Your BMW is equipped with both front and rear parking sensors called Park Distance Control, or PDC. The sensors monitor the areas at the front and rear of the car and issue an audio and visual alert to potential obstacles.
