Pinpoint Tests Purpose

WARNING: This page is about a different car, the 2020 Ford Fusion. 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 connector at the electronic steering actuator to the in-line connector in the engine compartment. If these circuits are working correctly, the test then directs to check the TCCM and wiring harness.
