Some 2016-2017 Focus RS vehicles built on or before 02-Aug-2017 may exhibit an Unable to Change Drive Mode message in the instrument panel cluster (IPC) and/or an illuminated malfunction indicator lamp (MIL) with DTC P26FE stored in the powertrain control module (PCM) memory. Reprogram the PCM to the latest calibration using Integrated Diagnostic System (IDS) or Ford J2534 Diagnostic Software (FJDS) release 106.04 or higher.
