Identify which ADAS features on a specific vehicle rely on a windshield-mounted camera (lane-keeping, forward collision warning, adaptive cruise control) before authorizing a windshield replacement, using NHTSA's vPIC VIN decoder.

Steps

  1. Call GET https://vpic.nhtsa.dot.gov/api/vehicles/DecodeVinExtended/{VIN}?format=json&modelyear={YEAR} (model year optional but recommended for correct decoding).
  2. In the Results array, read the Value field for camera/ADAS-relevant variables: Lane Departure Warning (LDW, VariableId 102), Lane Keeping Assistance (LKA, 103), Adaptive Cruise Control (ACC, 81), Forward Collision Warning (FCW, 101), Crash Imminent Braking (CIB, 87), Pedestrian Automatic Emergency Braking (171), and Lane Centering Assistance (194).
  3. Treat a null/blank Value as 'NHTSA has no data on this field', not as 'feature absent' — this is stated explicitly in the API's own response Message text.
  4. For batch screening of shop work orders, use DecodeVINValuesBatch (max 50 VINs per call) instead of one call per vehicle.
  5. Cross-check any positive/blank result against the OEM build sheet or a windshield-camera calibration target list before deciding calibration is unnecessary.
