How should the technician proceed if a vehicle fails the Crankcase Visible Smoke Test?

• A. Enter F for defective, provide documentation, and complete a Visible Smoke Test failure consumer information sheet
• B. Retest immediately
• C. Skip documentation
• D. Inform owner only

Answer: (A)

When a vehicle fails the Crankcase Visible Smoke Test, the important action is to formally document the failure and inform the owner with the proper information. The technician should mark the vehicle as defective in the data system, ensure all required documentation is completed, and provide the Visible Smoke Test failure consumer information sheet to the owner. This sheet explains what the failure means, what the next steps are, and how to proceed with repairs and potential retesting. Retesting after repairs is appropriate, but the immediate step after a failure is clear documentation and informing the owner. Skipping documentation or only informing the owner does not satisfy the proper procedure.
