Causes

  • Intermittent or failed CAN/LIN network communication
  • Damaged wiring or poor connector/terminal connection to Side Obstacle Detection Module C
  • Loss of module power or poor ground
  • Failed side obstacle detection sensor (radar/ultrasonic/lidar) or sensor harness
  • Corrupted firmware/configuration or software mismatch after service or update
  • Module internal fault (processor, memory, or I/O failure)

Symptoms

  • Side obstacle detection / blind spot alerts disabled or unavailable
  • Driver information message or warning lamp related to side obstacle detection or ADAS
  • Intermittent or constant DTC U054F stored in memory
  • Reduced or degraded ADAS functionality on that side of the vehicle
  • Possible chimes or error messages at startup

What to check

  • Use a scan tool to read all stored U-codes, freeze frame, and module network status
  • Check presence and update rate of the Side Obstacle Detection Module C messages on the vehicle bus
  • Inspect harness and connectors at the module and sensors for corrosion, bent pins, or damage
  • Verify module supply voltage (battery voltage with ignition on) and ground integrity
  • Check for other communication or data integrity DTCs on related modules
  • Perform wiggle test on wiring while monitoring live data for dropouts

Signal parameters

  • Module presence / Node ID on network (module should respond to diagnostics)
  • Message update rate (expected frequency; e.g., 5–20 Hz depending on OEM spec) — check for missing or irregular intervals
  • Data fields such as SideObstacle_Status (OK/INVALID), ObstacleDistance (within expected range), SensorHealth flags
  • Checksum/CRC field validity where used by the protocol
  • Supply voltage at module: typically ~11–14 V with ignition on
  • CAN bus idle voltages and recessive/dominant levels per OEM (use scope or multimeter to check differential bus activity)

Diagnostic algorithm

  1. Read and record all U-codes and related codes from all control modules; note freeze frame and occurrence conditions.
  2. Attempt to clear the code. If the code returns immediately, proceed with network and power checks.
  3. Inspect visually: connectors, pins, harness routing, signs of water ingress, and physical damage at module and sensors.
  4. Verify module power and ground with a DVOM at the module connector; repair any low voltage or poor ground.
  5. Using a scan tool or CAN/LIN sniffer, confirm the module is present on the bus and check message IDs and update rates; capture several seconds to look for data corruption or missing messages.
  6. Perform a wiggle test and load test on wiring while monitoring live data to identify intermittent faults.
  7. If bus errors are present, isolate by disconnecting other nodes or sensors per OEM procedures to find the faulty device or segment.
  8. If wiring and network are good but the module sends invalid data, check for available software updates or reflash the module per OEM instructions.
  9. If reflashing does not correct the issue, substitute a known-good module or sensor (if available) and retest.
  10. After repair or replacement, clear DTCs and verify normal operation through road test and live data confirmation.

Likely causes

  • Faulty or loose connector at the Side Obstacle Detection Module C
  • CAN bus line fault (short to battery/ground/other node) or missing termination
  • Module not powered or poor ground connection
  • Sensor upstream of the module producing invalid readings (hardware failure)
  • Software/parameter mismatch after an incomplete reflash or module replacement

Fault status

⚠️ Status
Invalid data received from Side Obstacle Detection Control Module C. Communication or data integrity error detected — check module connection, power/ground, bus messages, and module software.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1.5-3.0 hours
