Why is the Bora's reversing radar not beeping?
2 Answers
The reasons why the Bora's reversing radar is not beeping include whether the radar host line is loose; the buzzer is damaged; or the wiring at the bumper is damaged. Here are the specific details: 1. Whether the radar host line is loose: If the reversing radar is not beeping, first check whether the power cord of the host is properly connected and whether there is current; then check if the radar host line is loose. If neither of these is the issue, the problem may lie with the radar itself. 2. The buzzer is damaged: If the problem is confirmed to be with the reversing radar, the first possibility to consider is that the buzzer is damaged. In this case, you need to purchase and install a new buzzer. Also, recall whether your car has undergone any recent modifications. If so, it's possible that the reversing radar's wiring was damaged during the modification process. This requires taking the car to the original repair shop or a 4S store for inspection. 3. The wiring at the bumper is damaged: When the reversing radar is not beeping, 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 doesn't, check whether the connection switch of the reversing light is broken. You can also see if the computer displays any fault codes. If none of these issues are present, then check whether the reversing radar itself has a problem.
I've been driving a Bora for several years. When encountering a situation where the reversing radar doesn't beep, the first thing that comes to mind is that the sensors might be covered by mud or bugs, as this is quite common when driving frequently or during rainy days. Wiping the areas around the rear probes with a clean cloth sometimes solves the problem. If it still doesn't beep, check the fuse box for the fuse related to the reversing radar to see if it's blown, and try replacing it with an inexpensive one. If the issue persists, it might be due to loose wiring or a faulty radar module, in which case you should visit a 4S shop to check the wiring connections or replace the module. Don't ignore small issues; if the radar fails while parking, it's easy to scrape other cars, which is too dangerous. Make it a habit to clean the probes during regular car washes to prevent problems. Last time, I spent a few hundred fixing the module, but safety is the top priority.
