Some 2015-2017 Ford Mustang vehicles equipped with a manual transmission and built on or before June 15, 2016 may exhibit a no-crank condition due to the CPP (clutch pedal position) switch being damaged.
If the CPP switch is damaged, install a new CPP switch and bracket, P/N HR3Z-11A152-A. The new switch includes a plastic bracket rotating the connector 90-degrees.
