Causes

Blown fuse or removed power to the image processing sensor
Poor or disconnected power/ground at the sensor
Damaged, corroded, or disconnected sensor connector or wiring harness
Broken or shorted network wiring (CAN, LVDS, Automotive Ethernet or proprietary link)
Faulty image processing sensor (internal electronics or firmware failure)
Control module or gateway fault preventing network messages

Symptoms

Diagnostic scanner reports U0267 and possibly related U-codes
Camera image missing or blank on cluster/infotainment screen
Loss or degradation of ADAS functions that use the sensor (lane assist, collision mitigation, surround view, etc.)
Warning or indicator lamp/message related to camera system
Intermittent operation of camera features or message appears only at times

What to check

Scan for U0267 and any other network or camera-related DTCs; note freeze frame data
Attempt to communicate with the image processing sensor using a diagnostic tool (module present/ID)
Visually inspect the camera/module, mount, and lens for damage or water ingress
Inspect and reseat the sensor connector; check for bent pins, corrosion, or contamination
Check related fuses and power/ground circuits for correct voltage and continuity
Inspect the network bus wiring (CAN or Ethernet) for chafing, breaks, or recent bodywork/repairs that could have damaged the harness

Signal parameters

Expected network response: module should appear on the vehicle network and reply to diagnostic requests (presence/ID)
CAN bus: typical bus bit rates include 250 kb/s or 500 kb/s; idle voltages typically near the vehicle-specific nominal (refer to manufacturer spec) — CANH/CANL around mid-rail when idle (~2.5 V) with correct differential signaling
Automotive Ethernet: link/activity indicators or link detection should show up if the vehicle uses Ethernet for the camera
Power supply: camera/module battery feed should show stable battery voltage (approx. 12 V) with ignition on; ground should be low resistance to chassis
If available, oscilloscope waveform should show valid network frames without excessive noise or distortion

Diagnostic algorithm

Read and record all codes and freeze frame data. Note whether the U0267 is active or historic and if other modules report camera losses.
Confirm whether the sensor appears on the network using a capable diagnostic tool (module list/node discovery). If the node is absent, proceed with wiring and power checks.
Inspect camera connector and harness for corrosion, water, damage, or disconnected pins. Reseat connector and secure latch.
Check fuses and measure power and ground at the sensor connector with ignition on. Repair any open circuits or poor grounds.
Verify network continuity: check for proper termination/resistance and measure CANH/CANL or Ethernet signals at the sensor connector and at the gateway. Look for short to battery or short to ground.
Perform wiggle tests and monitor communication while moving the harness to identify intermittent faults.
If wiring and power are good but no communication exists, attempt to communicate with the sensor from the gateway end. Swap or isolate segments if multiple cameras share a bus.
If possible, connect a known-good camera or replacement module to confirm whether the sensor or the vehicle network is faulty.
Check for and install any module software updates or reflash/reconfigure modules if required by the manufacturer procedure.
After repairs or replacement, clear codes and road-test to verify the U0267 does not return and that camera functions are restored.
If problem persists, consult detailed wiring diagrams and consider gateway/module replacement per manufacturer guidance.

Likely causes

Loose/disconnected connector at the camera/module
Power or ground fault at the sensor (blown fuse, open circuit)
Damaged network cable between the camera and gateway/ECU
Failed image processing sensor module
Gateway or network termination problem on the vehicle bus

Fault status

⚠️ Status

Lost Communication With Image Processing Sensor C — the sensor did not respond to network requests or is not present on the vehicle communications bus. Intermittent or no messages detected from that module.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1.0-2.5 hours
