PRELIMINARY INSPECTION
The following items must be checked before proceeding:

KNOW AND UNDERSTAND THE CONCERN
In order to properly diagnose a concern you must first understand the customer complaint or condition. Customer contact may be required in order for the technician to begin to verify the concern. You must understand the conditions as to when the concern occurs. For example:
- Hot or cold vehicle temperature.
- Hot or cold ambient temperature.
- Vehicle driving conditions.

After understanding when and how the concern occurs then proceed to verifying the concern.
