DTC U2016: Control Module Main Software: Description

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.
