appropriate. When performing corrective actions:
• Perform the corrective actions in the order listed (if applicable)
until the problem is resolved.
• Before replacing a part, slave in a replacement part to verify that
it corrects the problem. If so, verify that the problem recurs with
the original part installed, then replace the part and confirm that
the problem is corrected.
