1. I found thatreverse buzzer did not sound. First check whether the hosting power line is connected and whether there is a current; then check whether the radar host line is loose. If neither of the two, the problem may be on the radar itself.

2. If the problem is determined that the problem is reverse buzzer, the first thing to consider is that the beeurger is broken. At this point, you need to buy a beeurger and install it; in addition, consider whether your car is available recently. Modified. If this is done, the wire of the beeurgeer during the modification may be damaged.

3. When the reverse buzzer is not sounded, first check whether the line connection of the bumper is intact, and then check whether the reversing light is on when the reversing stall is lit. The connection switch of the lights is damaged. Then you can check whether the computer displays the fault code, and there is no problem with these items, and then check whether there is a problem with the reversing beeurist itself.

The above is the corresponding inspection steps of reverse buzzer, and several possible solutions. I hope you will not be caught off guard when you encounter this situation. The most important thing is to solve the problem in a timely manner to avoid greater disaster.
