Rear view camera does not work

The rear view camera can be installed in several places. on the trunk handle, in the license plate frame, on the bumper or inside the passenger compartment.

The units installed in the passenger compartment are less susceptible to impacts and other factors, therefore they work more stably. Most often, malfunctions of outdoor gadgets are caused by moisture ingress of the internal device, which can cause image defects or a complete failure of the electronics. Consider the main types of malfunctions, why the rear view camera does not work and how to solve problems.

Rear View Camera Shows In Mirror Image: How To Fix

Many drivers face problems when the rear view camera shows the image upside down, flips or flips the image. The reasons for such malfunctions can be associated with improper setup and installation of the device, choosing the wrong monitor. To reverse the picture and remove specularity, you need to change the settings in the MMS. To do this, go to the menu and disable the Mirror option. In some cases, you need to open the case and turn the eyepiece 180 °.

If these manipulations do not allow and the monitor continues to work in a mirror image, then it will make changes to the control scheme. The elements involved in changing the orientation of the picture usually have special markings. The option labeled FLP makes it possible to rotate the picture in the opposite direction in the vertical direction, and MIR helps to get rid of mirroring. To obtain a normal image of the picture, you must disconnect the corresponding jumpers.

Common mistakes when connecting a rear view camera

  • Meals are taken from different locations. In most cases, “” is taken from the reversing lamp, and “-” from the body. We strongly ask you not to do this, we even insist. In such cases, such a phenomenon arises as a potential difference, and at different points the voltage may differ and constantly change. This phenomenon affects the electronics of the connected devices and leads to destabilization and poor or unstable picture quality. ALWAYS take plus and minus from the same place. For example, from a monitor or head unit.
  • The power supply is connected to a pulsating signal from the reversing lamps. In many cars, especially German ones, the signal on the reversing lights is pulsating. This is done specifically to diagnose the health of the light bulb in the headlights. So, if you have just such a signal, you need to align it and install a filter, which, in turn, must be separated from the system by an LED. If you put a capacitor to smooth the signal, but do not separate it from the standard system, then the smoothed signal will go to the reversing lamp, and the on-board computer (the unit that processes this lamp) will receive incorrect data. (see video).
  • Camera connection according to the principle of continuous operation without using a voltage converter. Then there is a very high probability that your camera will simply burn out. And by the way, this happens repeatedly.
  • Mismatch between the video signal standard of the camera and the car multimedia system.

Connecting the power of the rear view camera in the car.

Connecting the rear view camera power is an important and much more time-consuming process than it might seem at first glance. Incorrect power supply can lead to damage to the device itself, damage to the wiring of the car, incorrect operation of the camera, or poor or unstable picture quality.

First of all, “” and “-” of all connected devices must be taken from the same place. It is an axiom and a cornerstone of connecting electronics in a car.

Secondly, study the logic of the installed equipment. As a result, the connected camera should not stand out from the overall picture. What does this mean in practice:

If, according to the logic of the already installed equipment, all the electronics are turned on when the power is supplied to the head unit / monitor, then the camera must be connected accordingly. In many cars, the standard reversing camera (even if it is not there) is designed to turn on simultaneously with the ignition of the car. This approach provides an already warmed-up matrix and excellent image quality, especially in the dark, and also, in some cars, activates the video input for the camera.

  • If you want to connect the camera in this way, you need to study the minimum power threshold of the camera and use a voltage converter. This is a small block that, from the input 7-30 V, outputs the voltage required for the camera at the output. It must be selected depending on the battery of the camera itself. For example, in our range for this purpose there are voltage converters for 5, 6 and 7.5 V, respectively.
  • If the rear-view camera (note, not the image from the camera, but the camera) is activated when the reverse gear is turned on, you can connect the power to the reversing headlights. If there is a “clean” plus and minus, feel free to connect. If the signal is pulsating (PWM ripple), then to equalize the signal, you must use a filter, for example, a capacitor.

This, in fact, is all the steps that you need to perform to configure the devices. Now when you turn it on, yellow lines will start to appear to make parking easier. Remember that any subsequent disassembly may require subsequent reconfiguration of the device.

Blinking rear view camera

Flickering and blinking of the screen may be due to poor signal quality. To eliminate the problem, it is necessary to check all the contacts of the wires, make sure that the cable connections are intact and that there are no insulation faults. In the presence of more complex breakdowns, if the camera has completely failed, you will have to check all the electrical equipment. The process consists in dismantling and disassembling equipment, cleaning contacts and boards.

If your camera stops working, you can find and fix the breakdown yourself. Repairs are made according to the following scheme:

  • before dismantling the equipment, check the power supply of the device using a special tester, the voltage should be 12 volts;
  • disconnect the power cable;
  • unscrew the fastening elements and remove the equipment;
  • clean the gadget with a soft cloth, remove traces of rust and oxidation from the power connectors;
  • remove the body, check the condition of the gaskets and, if necessary, replace them;
  • inspect and clean all parts from dust;
  • check the working board for swollen capacitors and damaged elements, replace the failed parts by soldering;
  • assemble the gadget in reverse order.

After installing the electronics in place, it is very important to correctly adjust all settings and check the equipment operation. If, after all the above manipulations, the device still does not work, it is better to seek qualified assistance at the service center.

Briefly about the technical device

Why does the rear view camera not work when reverse gear is engaged?

Many drivers become anxious when they notice that the rear view camera is not working. But if you take the right measures and start a system recovery, the problem can be fixed in a short time.

Typical rear-view camera malfunctions

Most often, this device is located in the car in three places. This is either the trunk lock (handle), or the frame for the license plate illumination, or it can be installed in the cabin (in station wagons).

As practice shows, cameras that are decided to be installed directly in the cabin suffer least of all from any problems. After all, they are not exposed to aggressive environmental influences. This effect primarily refers to moisture entering the device.

The ingress of water into the device can lead not only to its complete failure to work. Defects in the image may occur. Often, car owners complain that the camera does not show the image or the picture looks cloudy. Most likely, the reason for this is precisely the ingress of moisture into the rear view camera.

How to fix: removing the camera and repairing it yourself

If the rear view camera constantly or periodically does not work, the repair is carried out as follows:

  • Before starting repairs, it is necessary to check the voltage supply to the device. After the user has connected the cable, the multimeter is taken and the power supply of the wire is checked. The red plug of the tester is inserted into the cable itself, and the black plug is connected to its metal part to provide ground. If the connection showed 12 volts of voltage, then the power is supplied to the device, respectively, the camera is further dismantled.
  • The power cable is disconnected from the camera.
  • With a screwdriver or wrench, the trim is removed (it all depends on the design features of the car). First, the rear tailgate trim is removed, then the nuts securing the device are unscrewed. Usually the camera is attached using two self-tapping screws, which are unscrewed with a screwdriver.
  • Clean the camera with a clean, dry cloth. Rust traces on the surface of the device must be removed, oxidation from the power connector is also removed.
  • Then the screws are unscrewed, which fix the component parts of the case. These elements are susceptible to oxidation, so you need to be careful when unscrewing them.
  • If moisture gets on the body, it is dried.
  • In case of wear or damage, the seals are replaced. The devices use two rubber bands (gaskets). One of them is located on the lens of the gadget, the second is at the junction between the plastic elements and the body.
  • The internal elements of the device are visually inspected. If swollen capacitors or other damaged elements are visible on the working board, they must be replaced by soldering. Before making repairs, clean and remove all traces of debris and dust.
  • The camera is assembled in reverse order. To ensure high tightness, it is recommended to treat the joints with silicone.

According to the instructions, the main task when setting up is to adjust the parking lines that the camera should show first.

  • A standard block of wood is taken. It is desirable that the length of the product is 2 meters, and its width is 2-3 cm.
  • The workpiece is placed at a distance of about 1 meter from the central part of the rear bumper. It is important that the edges of the wooden beam extend beyond the sides of the vehicle by approximately the same distance.
  • Then the driver gets into the cabin and enters the camera settings service menu. In some cars, you will have to perform additional actions, for example, activate and deactivate the side lights.
  • The brand of the vehicle is selected.
  • After turning on the device, the steering wheel is twisted: first all the way to the right, and then to the left.
  • The button “Next” is pressed, an automatic rectangular contour will appear on the screen of the device. The buttons are used to move the bar image to the center of the screen. Then the selected action should be confirmed.

In the absence of a wooden block, you can do this:

  • You will have to use three points, which are measured from the top edge of the rear bumper. Each of the elements has a step of 10 cm, respectively, the first point is 10 cm, the second is 20 cm, the third is 30 cm.
  • From each point, you need to set the camera’s visibility range with a step of 30 cm.
  • As a result, the first point has a range of 30 cm, the second. 60 cm, and the third. 90 cm.Taking into account this scale, you can correctly calculate the distance to the obstacle.

Reasons why the rear view camera does not work and troubleshooting instructions

If the rear view camera does not work, first of all, it is necessary to carry out a visual diagnosis of the device, and then make sure that there is power and the integrity of the wires. In the event of a breakdown due to poor contact or improper installation, the problem can be solved independently by reinstalling the gadget or replacing the electrics. If this does not help, the camera will have to be dismantled in order to repair or replace damaged elements, for example, a burnt board or swollen capacitors.
