Page language: EN

Causes

  • Corrupted or malformed CAN/LIN message from Image Processing Module A
  • Faulty image processing module (software or hardware)
  • Intermittent or permanent wiring/connectors fault between module and network
  • Low or unstable power supply or poor ground to the image processing module
  • ECU software mismatch, calibration or codec/configuration error
  • Network interference, excessive bus errors or missing termination

Symptoms

  • One or more driver-assist/vision features disabled or degraded (lane keep, automatic braking, adaptive cruise, etc.)
  • Warning or caution lamp for camera/ADAS systems
  • Stored related U-codes or image-module specific fault codes present
  • Possible intermittent operation of camera-based features
  • Reduced or no camera image available to other modules or displays

What to check

  • Connect a capable scan tool and read all DTCs from all modules; record freeze frame and occurrence counters
  • Check for additional network U-codes (U0100, U0121, etc.) that indicate other module communications issues
  • Visually inspect connectors and wiring at Image Processing Module A for corrosion, damage, or water intrusion
  • Verify module power and ground voltages at the module connector with key on; compare to specification
  • Perform CAN/LIN bus diagnostics: check bus voltage idle, termination, and error counters
  • Check for recent software updates, incorrect module coding, or partial reflash attempts

Signal parameters

  • Presence and frequency of image-module CAN/LIN messages (message ID and expected Hz)
  • Message payload validity: CRC/checksum, message counter rollover, timestamp consistency
  • Key diagnostic signals: camera/module status flags, error codes, frame sequence number
  • Bus physical layer: CAN high/low voltages at idle (~2.5V), dominant/recessive transitions, and bus error counters
  • Module supply rails (e.g., 5V/12V) and ground voltage at connector
  • Receive error counts on gateway/receiving module (rx error frames, frame loss)

Diagnostic algorithm

  1. Retrieve and document U053B and all other DTCs and freeze frame data from all modules. Note occurrence pattern (ignition cycles, temperature, events).
  2. Review service information for TSBs, required calibrations, or required reflash files for Image Processing Module A.
  3. With scan tool, monitor the image-module CAN/LIN messages: verify message IDs are present, frequency is stable, and payloads include valid sequence counters and checksums.
  4. Inspect connectors and harness for the image module. Unplug and inspect pins for corrosion, bent pins, or moisture. Repair as needed.
  5. Measure module supply and ground at the module connector with key ON. Repair any supply or ground issues. Verify termination resistors on CAN bus if applicable.
  6. If bus messages are missing or corrupted, perform a bus-capture during the event and analyze for collisions, bus-off conditions, or a particular node flooding the bus.
  7. If wiring and bus are good, attempt reprogramming or software update of Image Processing Module A per manufacturer procedure; ensure correct calibration and coding.
  8. If the fault persists after wiring and software verification, isolate by replacing the image processing module or camera assembly and re-test.
  9. Clear codes and perform drive/functional tests to confirm repair. If intermittent, perform road test under conditions that reproduced the fault and recheck logs.

Likely causes

  • CAN/LIN wiring open, short to battery/ground, or corroded connector to Image Processing Module A
  • Image Processing Module A software fault or failed reflash/calibration
  • Intermittent power/ground to the module causing corrupted messages
  • High bus error count or other modules flooding the network causing corrupted frames
  • Module misconfiguration after replacement or incorrect firmware

Fault status

⚠️ Status
Invalid data received from Image Processing Module A — messages failed validation (corrupt/malformed or unexpected format).
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1-4 hours
