Invalid Data Received From Image Processing Sensor I
AI status

Completed
100%
Causes
- Faulty image processing sensor (camera) or its internal electronics
- Damaged, corroded, or loose connector or wiring harness to the sensor
- Intermittent or low power supply or poor ground at the sensor
- Bus communication errors (CAN/CAN-FD, Ethernet, or other in-vehicle network) or high error rate
- Software/firmware mismatch or corrupted calibration data in sensor or control module
- Electromagnetic interference or bus termination issues
Symptoms
- Malfunction indicator lamp (MIL) or warning message for camera/ADAS on dash
- Reduced or disabled driver assistance features (e.g., lane keep, automatic braking, adaptive cruise)
- Camera image warning or blank/garbled camera feed in infotainment/diagnostic view
- Intermittent faults that may clear then return
- Stored freeze-frame data showing vehicle conditions when fault set
What to check
- Retrieve full freeze-frame and event data with a capable scan tool; note related U-/P- codes and conditions
- Visually inspect camera and harness connectors for corrosion, damage, moisture ingress, or bent pins
- Check power supply and ground at the sensor connector with a multimeter (key on) following manufacturer voltage/ground reference
- Use a diagnostic tool to monitor bus traffic and confirm the sensor is sending frames and messages (packet rate, message IDs, CRC status)
- Scan network for other communication errors or nodes reporting faults (CAN error counters, bus-off nodes)
- Inspect for aftermarket devices or recent repairs that may affect wiring or bus termination
Signal parameters
- Image data messages should be present on the vehicle network when the camera is active (continuous frame or packet stream)
- Expected message frequency depends on system design — typically regular frame/packet bursts when camera powered (consult OEM specs)
- Messages should pass integrity checks (CRC/checksum) and include valid timestamps and expected payload ranges
- Power feed at sensor: stable reference voltage as specified by manufacturer (verify with a meter/scan tool)
- No excessive CAN bus error frames or repeated retransmissions during normal operation
Diagnostic algorithm
- Read and record all related DTCs, freeze frame, and live data with a manufacturer-level scan tool. Note when and how the fault set.
- Visually inspect the sensor assembly, connector, and harness routing. Repair damaged insulation, pins, or connectors as needed.
- Verify sensor power and ground at the connector with the ignition in the correct state. Repair any supply or ground issues.
- With a diagnostic tool or oscilloscope, monitor the vehicle network to confirm the sensor is transmitting and that message integrity (CRC, timestamps) is valid. Look for high error rates or bus-off conditions.
- Wiggle-test wiring while monitoring live data to reproduce intermittent faults; repair or replace faulty wiring or connector as required.
- Check for and apply any required software or firmware updates, and confirm calibration status. Reprogram or recalibrate the sensor following OEM procedure if indicated.
- If wiring, power, and software are verified good and the error persists, replace the image processing sensor and clear codes. Re-test and verify correct operation of affected systems.
- After repairs, perform any required relearn/calibration procedures and road-test to confirm the fault does not return.
- Note: Follow OEM safety and diagnostic procedures when working on ADAS cameras and vehicle networks.
Likely causes
- Connector contact corrosion or bent pins at the camera
- Broken or chafed wiring in harness near hinges or door/hood areas
- Sensor hardware failure (image processor or lens/wiring failure)
- High CAN bus error counters or missing expected message frames
- Outdated or mismatched firmware between sensor and master module
Fault status
Status
Invalid data received from Image Processing Sensor I — communication or data integrity error detected. Camera data not trusted; associated ADAS functions may be disabled.
