U0568Invalid Data Received From Image Processing Sensor C

U0568 means the module that receives data from the image processing sensor C, typically a camera used for driver assistance features, has detected invalid or corrupted messages from that sensor over the vehicle's communication network. The computer is not seeing a complete loss of signal but rather data that fails its internal plausibility or checksum checks, so it flags the sensor as sending unusable information.

Symptoms you may notice

  • A warning light or message for the driver assistance system, such as lane keeping or forward collision alert, appears on the dashboard.
  • The affected camera-based feature stops working or becomes intermittently unavailable.
  • A chime or text warning tells the driver that the sensor is blocked or unavailable.
  • Often no symptoms besides the warning light, especially if the vehicle does not rely on that camera for a primary function.
  • Other driver assistance features that share the same camera or network may also be disabled.
  • In some cases the vehicle may default to a reduced level of automation or disable adaptive cruise control.

Common causes, most likely first

  1. A poor or corroded electrical connection at the image processing sensor, often from water intrusion or a loose connector.
  2. A failing image processing sensor that is internally corrupting its data output.
  3. Damage to the communication network wiring between the sensor and the receiving module, such as a chafed or pinched harness.
  4. A software or calibration issue in the sensor or receiving module that causes data to be rejected as invalid.
  5. Low system voltage or a weak battery that causes intermittent communication faults across the network.
  6. A faulty receiving module that misinterprets valid data from the sensor.

How to diagnose and fix it

  1. Inspect the image processing sensor connector and harness for corrosion, water intrusion, or loose pins, and clean or reseat as needed.
  2. Check the vehicle battery and charging system to rule out low voltage as a cause of intermittent network faults.
  3. Use a scan tool to read all codes in all modules and check for related communication or voltage codes that point to a shared circuit.
  4. Verify the sensor's software and calibration status with a factory-level scan tool, and perform any available updates or recalibration procedures.
  5. Perform a wiggle test on the sensor harness while monitoring live data to catch intermittent wiring faults.
  6. If wiring and power are confirmed good, substitute a known-good image processing sensor to see if the invalid data fault clears.
  7. As a last step, diagnose or replace the receiving module only after all sensor-side and wiring causes have been ruled out.

What the code does not always mean

  • U0568 does not automatically mean the image processing sensor has failed; a dirty or obstructed camera lens can cause the sensor to output data that the receiving module rejects as invalid.
  • A weak or failing battery is a common hidden cause of U-codes because low voltage can corrupt network messages without setting a battery-specific code.
  • After replacing or disconnecting the image processing sensor, many vehicles require a calibration drive or a static calibration procedure, and skipping it can leave the code stored or set a new one.
  • Water intrusion into the camera housing or connector is a frequent culprit on vehicles with cameras mounted in mirrors, bumpers, or windshield brackets, and the damage may not be visible without removing trim.
  • The receiving module may store U0568 even when the sensor is working correctly if a software mismatch exists between modules after a repair or update.

Can I keep driving with U0568?

The vehicle remains safe to drive in most cases because the fault affects a driver assistance feature rather than core engine or braking control, but you should not rely on the affected camera-based system and should have it diagnosed promptly to avoid losing safety features.
