What Causes the Car Radar to Not Sound?
1 Answers
Here are the reasons why the car radar does not sound: 1. Poor connection: The power interface of the radar is not properly connected or the wiring is damaged. 2. Buzzer failure: The buzzer may be faulty, causing the radar not to sound. 3. Wiring issue: There may be a wiring fault at the bumper, leading to the radar not sounding. Below is additional information on the causes of car radar system failures: 1. No alarm from the reverse radar system: The symptom is that the reverse radar system does not respond when shifting into reverse or pressing the radar switch. The diagnosis is that the working power or ground circuit of the reverse radar system is not functioning. 2. Reverse radar system not activated: A common cause is that the parking assist conditions are not met, such as the vehicle being in parking mode or trailer mode. The solution may involve replacing the reverse radar or reactivating it. 3. Radar system indicates a fault: The symptom is that the radar system shows a fault when using the parking function. The diagnosis may point to a faulty sensor or an abnormal connection between the sensor and the controller. Replacing the controller or sensor may be necessary. 4. False alarms from the reverse radar system: The symptom is that the radar alarms even when there are no obstacles while using the parking function. The diagnosis may indicate a faulty sensor or a dirty sensor surface. Common issues include damaged sensors or water droplets/mud on the sensor surface; cleaning the dirt may resolve the issue.
