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  , and PCM  . When the switch is pressed, it signals the RFA  module, BCM  and PCM  that there is a request to either switch the ignition on or start the engine. The start/stop switch is connected to both modules as a backup in case of a failure. If there is a circuit failure to either module from the start/stop switch, the modules communicate the start/stop switch request to each other over the MS-CAN  .
