Pinpoint Tests Purpose

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2019 Ford Expedition, 2018 Lincoln MKZ, 2018 Ford Transit-350 HD, 2018 Ford Transit-350, and 2018 Ford Transit-250. However, it is still accessible from the selected car via links, so may be relevant.

To verify the PSCM wiring harness and connectors are OK. This test checks the connectors and wiring from the PSCM 3-pin connector at the steering gear to the in-line connector in the engine compartment. If these circuits are working correctly, the test then directs to check the PCM and wiring harness.
