Why is the reversing radar of GAC Trumpchi GS5 not making a sound?
2 Answers
The reversing radar of GAC Trumpchi GS5 does not make a sound due to loose or disconnected wiring at the rear bumper; the reversing light switch is not turned on; the fuse of the reversing radar is loose or disconnected; the reversing radar module or buzzer is damaged; or the obstacle behind the car is too low or too short. Solutions: If the reversing radar does not make a sound, first check whether the power cord of the main unit is properly connected and whether there is current; then check whether the radar main unit wiring is loose. If neither of these is the problem, the issue may lie with the radar itself. If the problem is confirmed to be with the reversing radar, the first possibility to consider is a faulty buzzer. In this case, you need to purchase and install a new buzzer. Additionally, recall whether the vehicle has undergone any recent modifications. If so, the wiring of the reversing radar may have been damaged during the modification process, requiring the car to be taken back to the original workshop or a 4S store for inspection. When the reversing radar does not make a sound, you can also check whether the wiring connection at the bumper is intact, then check whether the reversing light turns on when the reverse gear is engaged. If it does not, check whether the reversing light connection switch is faulty. You can also check whether the computer displays any fault codes. If none of these are the issue, then check whether the reversing radar itself is malfunctioning. Introduction to reversing radar: The reversing radar is a safety assist device for parking or reversing the car. It can inform the driver of surrounding obstacles through sound or more intuitive displays, relieving the driver's troubles caused by looking around when parking, reversing, or starting the vehicle, and helping the driver eliminate blind spots and unclear vision defects.
When I was driving the GAC Trumpchi GS5, the reverse radar suddenly stopped beeping, which was really unsettling. There could be several reasons: the radar sensor might be covered with mud or dust, preventing it from detecting obstacles; a fuse might have blown—check the fuse related to the reverse radar in the fuse box; wiring issues like a loose plug or a short circuit, which can happen easily in humid weather; a faulty control module or a broken speaker; or it could be a system setting error, like the volume being accidentally turned down to the minimum. I’ll start by cleaning the sensor and checking the fuse. If it still doesn’t work, I’ll take it to the 4S shop immediately because this feature is crucial for parking. Cleaning the sensor regularly during car washes can prevent blockages and extend its lifespan.
