Why is the Elysion reversing radar not beeping?
3 Answers
Elysion reversing radar not beeping reasons are as follows: 1. Obstacle is too low: When the obstacle is too low, the reversing radar may fail to detect its presence. 2. Obstacle is too thin: When encountering slender poles, the reversing radar may also fail to detect the obstacle. 3. Reversing radar switch is off: There is usually a control switch for the reversing radar on the central control panel inside the car. If it is turned off, the reversing radar will not work. 4. Reversing radar wiring fault: When the reversing radar wiring is aged or broken, the reversing radar will not function properly. 5. Reversing radar damage: After excluding all the above possibilities, it is highly likely that components such as the reversing radar, controller, or alarm are damaged.
I've been driving for over a decade and seen many cases of reversing radar malfunctions. If the radar on your Elysian isn't beeping, there's an 80% chance the sensors are covered in mud. Remember to clean the sensors after driving on muddy roads in the rain. It could also be that the system was accidentally turned off - look for the button with a 'P' on the dashboard and try pressing it to turn it back on. If there's no response at all, there's an 80% chance it's because the trunk is open affecting system startup, or a fuse has blown in that small box in the engine compartment. Loose wiring connections can also cause this issue - the plugs under the rear bumper are prone to water splashing and oxidation. The most troublesome scenario is a faulty control module, which would require a diagnostic computer to read the error codes. A non-functioning reversing radar is extremely dangerous - get it checked at a repair shop immediately, don't try to save those few hundred bucks.
I just encountered this situation last week - the radar on my Elysion suddenly went silent while reversing. Don't panic yet, first open the trunk to check if too many items are blocking the sensors. I recommend putting the car in reverse gear while the engine is warm, then get out and feel each sensor one by one - functioning ones will have a slight vibration. If you find one that's ice cold, that sensor is likely dead. A few days ago, my radar connector got wet during car wash and worked again after drying. By the way, aftermarket reverse cameras can easily interfere with the factory radar - check if any wires are exposed. Replacing sensors yourself isn't hard - you can buy the same model online for about a hundred bucks, but be careful with the clips when removing the rear bumper. If it still doesn't work, have the dealership check the main unit - the system might have crashed.
