How to Use Pinpoint Tests

Do not perform any of the pinpoint tests unless instructed to so by the Quick Test. Each pinpoint test assumes that a fault (malfunction) has been detected in the system with direction to enter a specific repair routine. Conducting any pinpoint test without direction from the Quick Test procedures may produce incorrect results and replacement of satisfactory components. Correct test results for Quick Test are dependent on the proper operation of related components/systems.

When performing the Pinpoint Tests, refer to wiring diagrams to locate wire circuits indicated in the test procedures.
