Pinpoint Test Purpose

WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2022 Lincoln Navigator, 2022 Lincoln Nautilus, 2022 Lincoln Corsair, 2022 Lincoln Aviator, and 2022 Ford Transit-350 HD. 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 VDM and wiring harness.
