This could fix your problem fairly quickly. Some techniques to fix a backup radar problem on Bmw X4?īefore making any repair on your Bmw X4, we advise you to start by nettoyer the bumper of your car because it is possible that dirt is blocking the transmission of ultrasound. may take the time to check, using the booklet of your Bmw X4, but be aware that this is quite rare. In this case, the reverse lights will not come on either.įinally, given that it is an electrical circuit, it is always possible that the fuse reversing radar blown. In other words the mechanisms do not engage when you put the reverse gear. Then you will have the continuous audible signal as soon as you engage reverse gear.Īnother possibility, even if it is less frequent, is that you have a concern on the rear contactor. which do not allow the diffusion of ultrasound. If this is your case, the reversing radar is likely no longer emit sound because a sensor is damaged or you have an irregular sound signal.Īnother possibility is that the sensors are clogged with impurities like mud, plants. Indeed when you had little ones shock in the back of your car, it is possible that this has moved the sensors, thus distorting the analysis of the radar. Attention, a reversing radar should not replace the controls in the mirrors.Īs stated above, the reversing radar works thanks to sensors located at the rear of your vehicle, so most often breakdowns will be related to them.

The central will receive the data and transmit an audible signal to the driver to allow him to estimate the distance he has behind the vehicle. Then they will transmit this information to a electronic control unit through electrical connections. The sensors therefore go time the reception time of the ultrasound echo in order to calculate the distance. To calculate this the catches project ultrasonic (ultrasonic waves) which when they reach the object will send back an echo. These sensors will calculate the distance between your car and an outside element, such as a wall or other vehicle. Note that generally the sensors are placed at a height of 50 cm from the ground on the bumper, in order to be able to assess the appropriate distance to ring. It works using sensors, usually 4, located on the rear bumper of your car. In this way the audible signal starts approximately at 1 meters from your vehicle and will become continuous at 5 cm. Usually intensity The signal accelerates as the distance decreases to intensify the alert. The latter goes ring as soon as you approach something behind your car. The reversing radar engages as soon as you engage the reverse of your Bmw X4.
