Start-Stop Switch

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

The start/stop switch is a momentary contact switch that is hardwired to the RFA  module, BCM-B  , and the PCM  . The start/stop switch is connected to both the RFA  module and BCM-B  as a backup in case of a switch or circuit failure. In the event of a switch failure or a circuit failure between the switch and one of the modules, the module that receives the start/stop switch request transmits the request over the MS-CAN  to the other module to enable ignition system operation.

The start/stop switch also has 2 LEDs  , one is used for switch illumination and the other to indicate ignition mode. The ignition mode LED  only illuminates when the vehicle is in RUN or START mode, it does not illuminate in ACC mode.
