Fixing the Rearview Camera Not Working on a 2015-2020 Kia Sorento

Symptoms

1. Camera Display Black or Blank: The screen remains black when the vehicle is in reverse.
2. Error Message: You may see a message such as "Camera Unavailable" on the display.
3. No Image: The camera does not provide an image, even when the vehicle is in reverse.
4. Intermittent Function: The camera works sporadically, displaying images at times and failing at others.

Diagnostic Steps

1. Check the Gear Shift Position:

   • Ensure the vehicle is in reverse gear. The camera should activate automatically when in reverse.

2. Inspect the Display:

   • Verify that the infotainment system is functioning correctly by checking other features (radio, navigation, etc.).

3. Examine the Camera Lens:

   • Inspect the rearview camera lens for dirt, ice, or obstructions that could be affecting visibility.

4. Check for Fault Codes:

   • Use an OBD-II scanner to check for any fault codes related to the camera or rear parking assist system.

5. Inspect Fuses:

   • Check the fuse associated with the rearview camera in the fuse box. Refer to the owner's manual for the specific fuse location.

Tools Required

• OBD-II Scanner
• Multimeter
• Screwdrivers (Phillips and flathead)
• Socket set
• Trim removal tool
• Electrical tape
• Replacement camera (if needed)

Repair Instructions

Step 1: Verify Camera Activation

1. Start the vehicle and shift into reverse.
2. Observe if the rearview camera activates. If it does not, proceed to the next steps.

Step 2: Check the Fuses

1. Locate the Fuse Box:

   • The fuse box is usually located under the dashboard on the driver's side or in the engine compartment.

2. Inspect the Relevant Fuse:

   • Refer to your owner's manual to find the specific fuse for the rearview camera (usually labeled as 'Camera' or 'Backup').
   • Remove the fuse using a fuse puller or pliers and inspect it. If the filament is broken, replace it with a new fuse of the same amperage.

Step 3: Inspect the Camera Connection

1. Remove the Camera Housing:

   • Use a trim removal tool or screwdriver to gently pry off the cover of the rearview camera, located above the license plate.

2. Check the Wiring:

   • Inspect the wiring harness for any signs of damage, such as fraying or corrosion.
   • Disconnect the camera connector and use a multimeter to check for continuity in the wires.
   • If the wiring is damaged, repair it using electrical tape or replace the affected section.

Step 4: Test the Camera

1. Reconnect the Camera:

   • Reconnect the wiring harness if it was disconnected.

2. Test the Camera Again:

   • Start the vehicle and shift into reverse to see if the camera now activates.

Step 5: Replace the Camera (if necessary)

1. Remove the Old Camera:

   • If the camera is still not working, it may need replacement. Carefully unscrew or unclip the camera from its mount.

2. Install the New Camera:

   • Follow the manufacturer’s instructions to install the new camera, ensuring all connectors are secure.

3. Reassemble the Housing:

   • Reattach the camera housing cover.

Step 6: Final Testing

1. Start the Vehicle:
   • Shift into reverse and check if the rearview camera displays an image.
2. Check for Error Messages:
   • Ensure that no error messages appear on the display.

Conclusion

If after following these steps the rearview camera still does not function, it may require professional diagnosis at a Kia dealership or certified repair shop, as there may be an issue with the infotainment system or more complex wiring issues.
