Diagnostic Steps

  1. Verify code presence with OEM-level diagnostic tool
    Expected: B000B code present in body control module or other module reporting
    Interpretation: Confirms code retrieval and module origin
  2. Check for other related body codes or freeze frame data
    Expected: Presence or absence of additional codes
    Interpretation: Additional codes may indicate subsystem context (e.g., seat sensors, airbags)
  3. Inspect wiring and connectors in body/safety systems if applicable
    Expected: No shorts, corrosion, or disconnected connectors
    Interpretation: Wiring issues can often trigger undefined or reserved codes
