Do you own a vehicle that has a rear vision system or, in better terms, a camera to help you while backing up? If you do, you may have seen the ‘service rear vision system’ warning message on your infotainment screen. It may occur on a black, grey or blue screen. The message appears when you engage the reverse gear. It’s quite annoying, considering the convenience of the system.

But why does it appear? Why will your vehicle display the ‘service rear vision system‘ warning message? Typically, it is a way to inform you there is a problem with your backing-up camera system. But remember, this system has a series of components involved to give you the rear view when reversing. So, an issue with any of them might cause the rear vision system to fail and display the message. The vehicle computer will alert the system, an error code will be triggered, and you will receive the message on the screen every time you want to reverse.

Common problems that may trigger the ‘service rear vision system’ warning include the following:

  • No rear camera was detected: It’s the most common reason we’ve come across. A disconnected component in the system will cause an alert and error signal to be sent to the computer. It could be a disconnected camera, a loose connection, or a blown rear vision system fuse. The video processing module may also be offline due to a system error or another issue in the car computer, causing it to act up.
  • Inadequate image quality: The computer may also detect compromised rear vision system clarity. It could be a broken camera lens, camera vision blocking or something that prevents the camera from getting a clear image.

It’s a common issue with GMC vehicles, mostly the Silverado trucks. If your car or truck displays this message, you may want to get yourself an OBD-II Scanner to retrieve the error codes triggering the message. Keep in mind some vehicles may have a complex computer system, and the cheap scanners might not work.

Once you know where the rear vision system is, inspect it and fix it appropriately (refer to the section below.) You can also avoid the hassle and get repaired by a professional technician as soon as possible. Getting it serviced will prevent potential safety hazards from arising due to the rearview camera not operating correctly when reversing. Addressing the issue is important to ensure confident and careful driving when navigating in reverse.

How to Fix ‘Service Rear Vision System’

If you’re car is showing the ‘service rear vision system’ message, there are a few things that could have happened to cause the problem. Here are some of the most common causes that can trigger the alert and how you can fix them:

Blown Fuse

The rear vision camera system requires power to function properly. A dedicated fuse provides electricity to components like the camera unit and wiring. Over time, especially with older vehicles, this fuse can become overstressed and blow out. When this occurs, it cuts power to the entire system, resulting in an error message. Tracking down and replacing a blown fuse is often a simple solution.


  • Inspect the fuse box for a blown fuse related to the rear camera.
  • Check the car manual or the fuse box cover for the fuse position and number. 
  • If blown, replace the fuse with the correct amperage fuse.

Faulty Wiring or Connections

All electrical components in the rear vision system rely on intact wiring and robust connections to transmit camera footage and signals. Regular vibration from driving and environmental factors like heat, cold, and moisture can cause the wiring to deteriorate or break over time. Connectors may also loosen or corrode. Any interruption to the circuit between the camera and display triggers the fault notification.


  • Check the rear vision wiring camera system wiring for damage, cracks, or loose connections.
  • Retighten or replace damaged connections.

Dirty or Damaged Rear Camera

As the sole visual sensor, the rear camera lens must stay clean and clear to capture an unobstructed view. Dirt, dust, water spots, or physical dents can all obstruct the field of view. Over prolonged sun exposure, cameras may fade or stop working entirely. Any issue with light reception or sensing triggers the system fault message.


  • Clean the rearview camera lens with a mild cleaner.
  • Inspect the camera for damage or visible obstructions.
  • Replace the camera if damaged or visibility is still obstructed.

Failed Video Processing Module

This electronic control unit is the central mediator between the camera and the display. It processes raw footage, adds elements like guidelines, and transmits the final image. If the module malfunctions or can no longer communicate properly, the display will be unable to show the rearview, thus triggering the error notification.


  • Update module software if applicable
  • Have the module tested by a professional
  • Replace the module if found to be faulty

Water Intrusion

Rain, wash water, or other moisture sources can seep into the rear camera housing or wiring connections if seals are damaged or faulty. Even minor water intrusion introduces a corrosion risk that leads to electrical faults over time. Camera housings that are purposely sealed need repair if breached.


  • Inspect the camera unit for water intrusion or corrosion.
  • Replace damaged seals and refit the rear vision camera unit.

Software Issues

The rear vision system functions largely through software programming and codes on newer vehicles. Glitches, bugs or outright failures in this coding can interfere with normal camera processing and display control. Software issues may only be rectified through module re-flashing by a dealer technician.


  • Update the rear vision camera software if applicable.
  • Consult dealer for latest software/firmware versions.
  • Re-flash modules if necessary.

Obstructions Blocking Camera View

If fitted incorrectly, temporary fixings like bike racks or cargo can unintentionally block the camera lens. Stowed luggage pressing on the camera is another potential visual obstruction that impedes the system. Ensuring a clear line of sight minimizes fault chances.


  • Inspect the rear vision camera path for temporary blockages.
  • Adjust or remove interfering attachments.
  • Move stored items away from the rear vision camera range.
