Push Button Start System: Notes

WARNING: This page is about a different car, the 2012 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.

The Remote Function Actuator (RFA) module applies battery voltage to the same circuits that a conventional ignition switch uses to achieve 3 of the 4 standard ignition states (OFF, ON and START). Unlike a conventional ignition switch system, this push button start system does not have a driver accessible ACC mode. The RFA module automatically cycles through the ACC mode when the driver cycles the vehicle to the ON mode. The RFA module receives input from the following:

Clutch Pedal Position (CPP) switch (manual transaxle)
Cruise control deactivator switch (automatic transaxle)
Intelligent Access (IA) key (wireless input)
Park detect switch (automatic transaxle)
Start/stop switch

The RFA module uses input from the IA key to authorize use of the vehicle. The RFA module uses input from the start/stop switch, the park detect switch (automatic transaxle), the cruise control deactivator switch (automatic transaxle) and/or the CPP switch (manual transaxle) to transition between ignition modes.
