  1. Verify OBD-II readiness monitors are complete (not recently cleared) using a full protocol scan.
  2. Compare dashboard mileage to ECU-stored odometer modules where accessible.
  3. Pull permanent and pending DTCs — not only stored codes visible on the dash.
  4. Run a MotoMetrics on-site scan for Kia Niro before signing the bill of sale.
