B1142 LINCOLN MeaningOn vehicles equipped with a conventional ignition switch, fused battery voltage is sent to the ignition switch from Battery. This voltage is then sent to the Body Control Module (BCM) along one of 3 circuits, depending on ignition switch position.
On vehicles equipped with a start/stop switch, fused battery voltage is sent to one set of contacts in the start/stop switch from Battery. When the switch is pressed, this voltage is then sent to the Body Control Module (BCM), the Remote Function Actuator (RFA) module and the PCM. The other set of contacts in the start/stop switch connects the BCM to ground. When the switch is pressed, the BCM detects this ground signal and takes appropriate action.
