This may be due to a calibration mismatch in the PSCM which has been resolved in the Ford database. If DTC C1110:56 is stored in a replacement PSCM after completing programmable module installation (PMI), start a new session using the latest software version of the Ford Diagnosis and Repair System (FDRS) scan tool then run the \"PSCM - Programmable Module Installation (PMI)\" application again. When FDRS asks if the original module is installed, select \"No\". If DTC C1110:56 is stored in the original PSCM after performing the PSCM configuration, start a new session using the latest software version of the FDRS scan tool, then download and run the \"PSCM - Power Steering Control Module (PSCM) Software Update\" application.
