Verifying Customer Complaint

COMPLAINT VERIFICATION
- Whenever Possible, The Technician Should Personally Verify The Complaint.
- Having Experienced The Malfunction, You Will Be Less Likely To Attempt To Repair A Non-Existent Fault.

MALFUNCTION VERIFICATION
- Automotive Control Systems Are Easily Misunderstood, Leading To Repairs That Attempt To Force A System To Perform In A Way It Was Never Intended To.
- Always Compare System Operation To Normal System Operation As Described In Either The Owners Manual Or DESCRIPTION AND OPERATION. When Possible Compare Vehicle Operation With That Of A Known Good Vehicle.

PREVIOUS REPAIRS
- The Vehicle Repair History Can Provide Explanations To Unusual Complaints Which Elude Normal Troubleshooting Attempts. Incorrect Components Or Unapproved Repairs Can Have Subtle Influences On Seemingly Unrelated Systems.
- Always Attempt To Get The "whole Story" From The Customer.
- When Possible, Check The System Or Component Which Was Last Repaired.
