Another Focus glitch
Some 2012-2014 Ford Focus vehicles equipped with reverse park aid sensors and built on or before 8-16-2013 may exhibit the IPC message center display indicating Rear Park Aid On/Off while driving forward after shifting from reverse.
1. Reprogram the IPC to the latest calibration using IDS release 87.02 and higher. Calibration files may be obtained at www.motorcraft.com.
2. Set the clock to current time, as it may have lost time during the programming procedure.
