How to Fix a Fallen Reverse Radar?
3 Answers
First, determine if the radar can be directly secured from the outside. If possible, this is the best solution. If external fixing isn't feasible, check if you can reach through the lower gap to secure it by hand or perform a simple disassembly for fixing. If neither method works or the fixing isn't sturdy, you'll need to remove the rear bumper for proper installation. Then reinstall the rear bumper to complete the radar installation.
Last time I noticed one of the parking sensor probes was missing, which gave me quite a scare. I immediately checked and found the mounting clip had come loose. I felt around with my hand and the position was still there. I looked for the toolkit in the trunk, took out a small screwdriver to clean the mounting point, then aligned and snapped it back in. After testing, the reverse signal returned to normal without spending a single penny. I recommend making it a habit to check the sensor fixation after parking, especially after going over many speed bumps where vibrations can easily loosen them. It's quite simple to DIY, saving a trip to the repair shop while improving safety awareness. Just test it several times during the process to ensure it's secure for peace of mind.
Common causes for reversing radar probe detachment are vibration or adhesive failure, which I've encountered twice before. DIY repair is straightforward: first clean the contact surfaces on both the car body and probe with a damp cloth, then secure firmly using heavy-duty double-sided tape. Be careful not to misposition it, as this could affect blind spot monitoring. If the probe is damaged, replacement units are affordable at just a few dozen yuan. I recommend checking probe looseness during monthly car washes by gently pushing them to confirm stability. Good prevention avoids accidents while reversing – safety comes first. These tips can extend your radar's lifespan.
