DTC U2016: Control Module Main Software: Description

WARNING: This page is about a different car, the 2018 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.

When the battery voltage to the PSCM is greater than 6 volts with the ignition ON and there are no DTCs present, the PSCM runs a self-test of the system software. If an error is detected, a DTC is set and the EPAS enters into a limited operation mode.

DTC U2016:47 (Control Module Main Software: Watchdog/Safety Micro-controller Failure) - Sets due to an internal failure in the PSCM software.
DTC U2016:48 (Control Module Main Software: Supervision Software Failure) - Sets due to an internal failure in the PSCM software.
