Power Steering Control Module (PSCM) Power Down

WARNING: This page is about a different car, the 2013 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.

The internal circuitry of the PSCM enables the PSCM to remain powered for 90 seconds after the ignition state has been switched to OFF. When carrying out diagnostic procedures that require DTCs to be cleared and a new ignition cycle to be started, make sure the ignition state remains OFF for a minimum of 90 seconds before switching to ON. This allows the PSCM to shut down completely and a new ignition cycle to be entered.
