What is the fault when the Cruze reversing radar does not sound?

[ZoeDella]

Cruze reversing radar does not sound troubleshooting specific reasons are as follows: 1. Specific reasons: Check whether the reversing radar wiring at the rear bumper is properly connected, check whether the reversing light is on when reversing, if not, check the reversing light switch, check the continuity of the radar wires, open the fuse box, use a multimeter to check the continuity of the reversing radar related fuses, the reversing radar module or buzzer is damaged and needs to be replaced. 2. Obstacles: Too low obstacles, generally obstacles below 10~15cm below the center of the probe may be ignored by the probe, and the closer the obstacle is to the parking space, the lower this height value will be, and the greater the danger. Too thin obstacles, because the sound wave signal emitted by the radar probe is narrow, there is a large blind spot when detecting thin obstacles, some isolation piles used to block vehicles on the road, and the diagonal steel cables on the utility poles are dangerous items. The radar is used to detect obstacles, and there are ditches behind the car, the radar will never respond.
