Pinpoint Tests
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The pinpoint tests are divided by component or system. Electrical pinpoint tests consist of a series of circuit checks to verify the integrity of the wiring harness between the PCM/ TCM and the solenoid or sensor. Mechanical pinpoint tests consist of a series of component tests and inspections to determine the root cause of the concern.
