Starting System - without Push Button Start: Overview: Notes
WARNING: This page is about a different car, the 2016 Ford Special Service Police Sedan and 2016 Ford Police Interceptor Sedan. However, it is still accessible from the selected car via links, so may be relevant.
The starter system controls the cranking of the engine. The starter motor is enabled by the starter relay when the relay is activated by the PCM. The PCM receives inputs from the ignition switch, BCM Run/start relay and TR sensor before activating the starter relay to crank the engine.
