Today, I started my truck and my LI started beeping as if there was an object in front of it. My truck is parked in the go position so there is nothing in front of the LI. After about a minute or two, the LI announces parking aid is deactivated and the beeping stops. What could be the cause of this problem? If the parking aid portion of the LI is messed up, does this mean the jamming portion is messed up as well?
