To begin, it's valuable to understand that the Jeep Grand Cherokee's Parksense feature will not function unless the key is turned to the ON position – trying to use it in accessory mode will not yield results. While this seems like a basic and common-sense point, it's surprising how many drivers misunderstand the system's operation. If you are experiencing issues with the system, the most frequent problem is likely a faulty or damaged sensor. Start by cleaning the sensors as thoroughly as possible, then examine the wiring as this is a common vulnerability in the Parksense system. Finally, you can use a digital multimeter to check a sensor's resistance and determine if it is operating correctly.
If the parking sensor of the Jeep Grand Cherokee is malfunctioning, it will be unable to spot nearby objects, making it unsafe to depend on.
