Do you wish you had a pair of extra eyes to help you avoid obstacles and collisions when parking your vehicle?
Parking sensors are devices that use electromagnetic or ultrasonic waves to detect the distance and location of objects around your car and alert you with audible beeps or visual displays.
However, parking sensors may sometimes malfunction or need to be reset for various reasons, such as:
- The sensors are dirty, damaged, or misaligned.
- The sensors are affected by external interference, such as weather, noise, or other vehicles.
- The sensors are not compatible with the vehicle’s electrical system or software.
- The sensors have been disconnected or replaced.
In this article, we will show you how to reset parking sensors in three common scenarios: after cleaning or replacing them, after changing settings or modes, and after interference from other devices.
How to Reset Parking Sensors?
Scenario 1: Resetting Parking Sensors After Cleaning or Replacing Them
One of the most common causes of parking sensor issues is dirt or debris blocking the sensor surface.
This can reduce the sensitivity and accuracy of the sensors, or even make them stop working altogether.
To fix this, you need to clean the sensors regularly with a soft cloth and mild detergent and avoid using abrasive materials or chemicals that may damage the sensors.
If cleaning the sensors does not solve the problem, you may need to replace them with new ones. This can happen if the sensors are cracked, dented, or corroded due to wear and tear or impact.
To replace the sensors, you need to remove the old ones from the bumper, disconnect the wiring harness, and install the new ones in the same position and orientation.
You may need to use a hole saw or a drill to make holes for the new sensors if they are not compatible with the existing ones.
After cleaning or replacing the sensors, you may need to reset them to make sure they work correctly.
The exact procedure for resetting parking sensors may vary depending on the make and model of your vehicle and the type of parking sensor system you have.
However, a general method that works for most vehicles is as follows:
1. Turn off the ignition and remove the key from the ignition switch.
2. Disconnect the negative terminal of the battery with a wrench or a socket.
3. Wait for about 15 minutes to allow the system to reset.
4. Reconnect the negative terminal of the battery and tighten it securely.
5. Turn on the ignition and start the engine.
6. Check if the parking sensor system is working normally by engaging the reverse gear and approaching an object behind the vehicle. You should hear beeps or see indicators on the display as you get closer to the object.
7. If the parking sensor system is still not working properly, you may need to consult a professional mechanic or refer to your vehicle’s manual for further instructions.
Scenario 2: Resetting Parking Sensors After Changing Settings or Modes
Another reason why parking sensors may need to be reset is that you have changed some settings or modes that affect their operation.
For example, some vehicles have different modes for parking sensors, such as on/off, front/rear, audible/visual, or sensitivity levels.
You may have accidentally turned off the parking sensors, switched them to a different mode, or adjusted their sensitivity to too high or too low.
To fix this, you need to restore the parking sensor settings or modes to their default values or to your preferred options.
The exact procedure for changing parking sensor settings or modes may vary depending on the make and model of your vehicle and the type of parking sensor system you have.
However, a general method that works for most vehicles is as follows:
1. Locate the parking sensor button or switch on your dashboard, console, or steering wheel.
It may have a symbol of a car with waves around it, or a letter P with waves around it.
2. Press the button or switch repeatedly until you see or hear a confirmation that the parking sensor system is on and in your desired mode. You may also see a light indicator on the button or switch itself.
3. Check if the parking sensor system is working normally by engaging the reverse gear and approaching an object behind the vehicle.
You should hear beeps or see indicators on the display as you get closer to the object.
4. If the parking sensor system is still not working properly, you may need to consult a professional mechanic or refer to your vehicle’s manual for further instructions.
Scenario 3: Resetting Parking Sensors After Interference from Other Devices
A third cause of parking sensor problems is interference from other devices that emit electromagnetic or ultrasonic waves.
These devices can include radio transmitters, cell phones, radar detectors, power lines, metal detectors, or other vehicles with similar parking sensor systems.
Interference can cause false readings, reduced sensitivity, or erratic behavior of the parking sensors.
To fix this, you need to eliminate or reduce the source of interference as much as possible.
The exact procedure for doing this may vary depending on the type and location of the interfering device.
However, a general method that works for most situations is as follows:
1. Turn off or move away from the interfering device if possible.
For example, if you have a cell phone or a radar detector in your car, turn it off or put it in airplane mode, or place it in a different location away from the parking sensors.
2. Check if the parking sensor system is working normally by engaging the reverse gear and approaching an object behind the vehicle.
You should hear beeps or see indicators on the display as you get closer to the object.
3. If the parking sensor system is still not working properly, you may need to reset it using the method described in scenario 1 above.
4. If the parking sensor system is still not working properly after resetting it, you may need to consult a professional mechanic or refer to your vehicle’s manual for further instructions.
