The best way to prove a repair was done is to show a Diagnostic Trouble Code (DTC) removal. You will need to give this documentation with your waiver application:

  1. Vehicle Inspection Report from the failed pre-repair emissions inspection that lists DTCs and other emissions inspection failures.
  2. Any diagnostic documentation supporting that repairs were necessary to fix the DTCs reported on the pre-repair Vehicle Inspection Report.
  3. Itemized repair invoices or parts receipts that prove the cost of the qualified repairs is more than the amount needed to get a waiver (cost of 'Shop Supplies' and 'Diagnostics' are not applicable).
  4. Post repair Vehicle Inspection Reporting showing:
  • DTC removed for repairs claimed.
  • "Pass" for:
    • Readiness Result
    • MIL-KOEO
    • DLC
    • OBD Communications
  • DTC Result: Fail during the post-repair inspection.
Estimate Based Waivers
  1. Most recent GVIP Vehicle Inspection Report recording a single DTC and a "Pass" for:
    • Readiness Result
    • MIL-KOEO
    • DLC
    • OBD Communications
  2. Documentation of DTC diagnosis (following manufacturer diagnostics) from a shop using a Missouri Recognized Repair Technician or one that specializes in the cause of failure (example: transmission shop).
