Conventional Ignition Switch Overview
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The conventional ignition switch is controlled by the ignition lock cylinder and key. The ignition lock cylinder and ignition switch are connected mechanically. Turning the ignition lock cylinder places the ignition switch into the desired position. The available ignition switch positions are:
- OFF
- ACC
- ON
- START
When placed in ACC or ON, the ignition switch provides voltage inputs to the BCM.
When placed in START, the ignition switch provides voltage inputs to the BCM and PCM.
