Park Pilot, also known as Assistive Parking, is a system designed to make the parking experience as smooth as possible. It also aims to improve the safety of those in and around the car by preventing collisions during parking.
The system uses sensors mounted around the car to detect obstacles and helps guide your car into the parking space with ease. However, like most technologies, Park Pilot is occasionally prone to errors and malfunctions.
In this article, we will discuss the causes of Park Pilot malfunction, how to fix it, and how to prevent it from happening in the future.
What is a Park Pilot Malfunction?
A Park Pilot malfunction occurs when something has gone wrong with the system that prevents it from working. This means that you won’t be able to use Park Pilot and its many helpful features until the cause of the malfunction has been addressed.
Park Pilot malfunctions can manifest as error messages on your dashboard, such as “Park Pilot malfunction Service Required” or “Parking pilot malfunction.”
Causes of Park Pilot Malfunction
There are several reasons that can lead to a Park Pilot malfunction. In most cases, the problem has to do with the parking sensors that the car uses to detect its environment.
Because of their location on the outside of the car, these sensors are exposed to the elements and other hazards that can affect their operation. The following are some common causes of Park Pilot malfunction:
Blocked by Dirt
One of the most common causes of Park Pilot malfunction is the external sensors being blocked by dirt or debris. This can happen after driving through muddy or wet roads.
The tires can throw up mud, water, or snow that sticks to the sensors and blocks them. This interferes with their ability to detect obstacles and can result in a malfunction.
Sensor Contains Water
The parking sensors are located on the outside of the car, usually on the front and rear bumpers. This exposes them to water, especially in rainy conditions and on wet roads. Water entering the sensors can affect their operation and cause a malfunction.
Damaged or Broken Sensor
The parking sensors are located on the bumpers of your car, which exposes them to bumps and collisions. They are sensitive equipment, and even a minor collision or impact is enough to stop them from working. A single damaged sensor is enough to cause the Park Pilot malfunction warning to appear.
Faulty Control Module
In some cases, the problem may not be with the sensors themselves but with the control module that manages the Park Pilot system. A faulty control module can cause the system to malfunction and display error messages on your dashboard.
Low Battery Voltage
If the battery voltage in your car is low, it can cause the modules controlling the Park Pilot system to behave unexpectedly, leading to a malfunction.
This is more likely to occur if your car has been sitting idle for an extended period or if the battery is not functioning optimally.
How to Diagnose a Park Pilot Malfunction
Before attempting to fix a Park Pilot malfunction, it is essential to diagnose the cause of the problem. The following steps can help you identify the cause of the malfunction:
- Visual Inspection: Check the rear and front bumpers for the parking sensors. They are typically located on the corners and center of the bumpers. Look for any visible mud, dirt, snow, or debris on the sensors. If you notice any obstructions, clean the sensors and see if the malfunction warning disappears.
- Listen for Sensor Ticking: You can manually check whether the sensors are working by using a cardboard tube or simply by placing your ear close to each sensor. With the car in reverse, the ignition on, and the engine off, listen for a ticking noise from each sensor. Sensors that are not ticking may be faulty.
- Check for Error Codes: Some vehicles allow you to access error codes related to the Park Pilot system using an OBD-II scanner or diagnostic tool. These codes can provide more information about the specific issue causing the malfunction.
- Battery Voltage: Check the battery voltage using a multimeter or by accessing the battery information through your car’s dashboard, if available. If the battery voltage is low, consider charging the battery before attempting any further troubleshooting.
How to Fix a Park Pilot Malfunction
Once you’ve identified the cause of the malfunction, you can often fix it within minutes. The following solutions can help you resolve a Park Pilot malfunction:
Clean the Sensors
If your sensors are dirty, simply wiping them clean with a damp microfiber cloth can resolve the malfunction. Make sure to dry the sensor afterward to prevent water from getting into it. Don’t use anything sharp or abrasive to scrape debris or mud off the sensor, as this could damage the sensor’s surface.
Remove Water from Sensors
If your sensors are filled with water, you can fix them easily without needing to open them. You can drive the water out by spraying the sensor with WD40 or any other oil-based lubricant.
After spraying the parking sensor, wipe it down with a rag to remove the excess oil and water.
Alternatively, you can use a can of compressed air to force water out of the sensor. Aim the nozzle at the creases surrounding the sensor, where it joins the bumper, and give it a few bursts of compressed air. The high-pressure air should force out any water in the sensor.
Replace Damaged or Broken Sensors
If cleaning the sensors hasn’t resolved the malfunction warning, you may need to replace a damaged parking sensor.
You can find a replacement sensor online, making sure to purchase one that is compatible with your car’s make and model. To replace the sensor, you’ll need a panel remover and a wrench, as well as the replacement sensor itself.
Follow these steps to replace a damaged sensor:
- Use the wrench to remove the bolts that hold the bumper to the car. Some of the bolts may be covered by panels or push pins, which can be removed with the panel remover.
- Locate the faulty sensor and remove it from the plastic sensor bracket.
- Remove the sensor from the wiring harness.
- Push the new sensor through the hole in the bumper.
- Slide the sensor bracket onto the new parking sensor to secure it in place.
- Plug the wiring harness into the sensor.
- Reinstall the bumper on the car.
After replacing the sensor, test the Park Pilot system to ensure it is functioning correctly.
Reset the System
In some cases, a simple system reset may resolve the malfunction. Disconnect the battery for a few minutes or pull the fuse for the parking module, if accessible, to force a reboot of the system. Reconnect the battery or replace the fuse and test the Park Pilot system to see if the malfunction has been resolved.
