What Is Parksense?

Before resolving the ParkSense Unavailable Service Required issue, let’s understand what ParkSense is. 

ParkSense is a combination of intelligent parking assistance systems developed by Jeep. These systems can include rear park assist, front park assist, and blind spot monitoring. It’s a safety feature that helps you avoid minor parking incidents by simplifying and enhancing your parking experience. 

Your Jeep has a network of sensors integrated into its front, rear bumper and other places like the side-view mirror. ParkSense helps you navigate parking spaces using the information gathered from those sensors.

ParkSense activates when you go into reverse gear, and your speed remains under 7-8 miles per hour. Its sensors constantly scan the area around your vehicle. Its scanning zone extends approximately 12 to 79 inches horizontally.

By scanning meticulously, ParkSense can detect objects, whether they’re moving or not, like humans, stationary posts, other vehicles, or any obstacle that may come in your path.

The moment ParkSense detects an obstacle, it immediately alerts you. An audible chime alerts you to the presence of the obstacle so that you don’t miss it. At the same time, your dashboard displays warning lights to indicate the relative distance and direction of the obstacle. The alert tone chimes faster as you get closer to the object. 

You have the option to turn the ParkSense system on or off. If you don’t want to use it, you can turn it off by pushing the button on the center console.

It seems to be a solid system. So, what does it mean when you see a ParkSense Unavailable Service Required warning? Let’s find out.

What Does the Parksense Unavailable Service Required Warning Mean?

When the ParkSense Unavailable Service Required warning message shows up on your dashboard, it tells you something’s wrong with your ParkSense system.

It means that the ParkSense system that uses sensors and intelligent software to help you park can’t operate normally because of an issue like a software glitch or something outside, like snow or dirt, messing with the sensors. Whatever the problem, the message tells us that the system can’t work and we need to fix it.

In simple terms, When you see this message, it means that your Jeep’s ParkSense system has failed, and it wants you to look into the problem and fix it.

In different cases, you may see additional warnings. If you see ParkSense Unavailable Wipe Rear Sensors or ParkSense Unavailable Service Required when you start your Jeep and listen to a single chime per ignition cycle, then the ParkSense Rear Park Assist System has an issue and stopped working. 

If you notice ParkSense Unavailable Wipe Rear Sensors or ParkSense Unavailable Service Required when you go into reverse and the message remains as long as you stay in reverse, then also the ParkSense Rear Park Assist System has an issue and stopped working. 

You may also see the ParkSense Unavailable message when you start your Jeep if you have a Jeep Renegade or Jeep Wrangler High Altitude. The warning comes when the ParkSense system can’t activate at the start-up.

Even though the ParkSense Unavailable Service Required warning is sometimes quite persistent and annoying, it occurs for specific reasons, which I have listed below. If you go through it, with some effort, you’ll arrive at the root cause of your problem.

Parksense Unavailable Service Required: What Are the Reasons?

ParkSense Unavailable Service Required clearly indicates that there is a problem that’s making ParkSense temporarily available. Several reasons can cause this issue. They are- 

Sensor Blocked Due to Dirt, Debris, or Snow

Over time, the sensors that detect obstacles around your Jeep can accumulate dirt, snow, or debris. These can obstruct the sensors, stop them from accurately measuring distances, and provide reliable readings. ParkSense may misinterpret this obstruction as a malfunction and produce the ParkSense Unavailable Service Required warning.

Sensor Malfunction 

ParkSense sensors integrated into your Jeep are sensitive and susceptible to wear and tear. Moisture and corrosion can also stop them from working correctly. When these sensors slowly deteriorate, they produce inaccurate readings or sometimes fail to detect anything at all. Then ParkSense signals to you that you need to check on the issue.

Sensor Misalignment 

If your ParkSense sensors are incorrectly positioned or aligned, it can trigger the ParkSense Unavailable Service Required message. When you replace your bumpers after accidents or other reasons, you can incorrectly position or align the sensors without knowing it and disrupt their accurate readings.

Electrical Short or Damage 

The sensors are connected through many wires and connectors. They ensure seamless communication. These wires can be physically damaged. Electrical shorts can also happen. It can stop communication, and the system will signal the occurrence of a malfunction.

TPMS Interference 

The Tire Pressure Monitoring System (TPMS) of your Jeep monitors the tire pressure all the time through the TPMS sensors so that the tire pressure remains optimal and alerts you when the pressure gets too low. These TPMS sensors are also in your spare tire. The proximity of these sensors to the parking sensors can result in signal interference. The ParkSense system analyzes this interference as an anomaly and triggers the warning message.

Environmental Factors

External conditions like condensation can impact sensor performance and contribute to sensor malfunctions. In cold weather, the condensation from the exhaust triggers the warning, and it disappears when the engine temperature reaches an optimal level or when the weather gets warmer.

Aftermarket Modifications 

You need to correctly position sensors according to their original orientation to get accurate readings. If you make modifications to your Jeep, it can impact sensor position, alignment, and direction. This can lead to distorted feedback and the warning message.

These problems typically make ParkSense temporarily unavailable and produce the ParkSense Unavailable Service Required error. So, how do you resolve this issue? Let’s find out.

Parksense Unavailable Service Required: How Do You Fix It?

Let’s go through the solutions one by one and get into the details:

1. Clean and Clear the Sensors

Before taking any other actions, wash your Jeep and thoroughly wipe the front and rear bumpers. Make sure that there is no dirt, dust, or debris blocking the sensors.

If your ParkSense sensors are blocked by dirt or snow:

  •   Wash the entire car. Pay attention to the front and rear bumpers.
  •   Gently clean the sensors. Use a soft cloth dampened with water and car wash soap.
  •   Dry the sensors using a dry cloth. Don’t use rough or abrasive cloths, as they can damage the sensor surface.
  •   Don’t apply excessive pressure, as this can harm the sensors.

If you use a washing station, quickly clean the sensors using a vapour jet or high-pressure washing nozzles. Keep the nozzles at least 4 inches (10 cm) away from the sensors to prevent scratching or poking.

2. Realign and reposition the Sensors

Proper alignment of sensors is crucial for accurate functioning. If you make any modifications or get into an accident, the alignment and the position of the sensors can become incorrect. First, make sure that the sensors are correctly positioned. Then carefully realign the sensors. This will ensure optimal sensor performance and accurate obstacle detection.
