Lincoln Nautilus: Cruise Control / Cruise Control - Overview. Description and Operation
Overview
The cruise control system is controlled by the PCM .
The
cruise control mode is selected from the steering wheel mounted
switches which are integrated into the steering wheel. Refer to Owners
Literature for additional information.
The
cruise control system maintains a selected vehicle speed between 32 kmh
(20 mph) or 30 kmh (18 mph) (metric cluster) and the maximum limited
vehicle speed. When a MyKey® restricted key is in use and maximum speed
limiter is turned on, vehicle speed is limited to 129 kmh (80 mph).
During
normal driving, the vehicle speed can vary slightly from the set speed
due to road conditions. The vehicle speed can fluctuate when driving up
and down a steep hill. If the vehicle speed decreases more than 16 kmh
(10 mph) below the set speed, the cruise control disengages.

System Operation
Body Control Module (BCM)
The BCM controls various systems by monitoring inputs from switches,
sensors and network messages from other modules on the HS-CAN1 and from
the GWM . Based on the inputs received, the BCM activates outputs. For
example, the BCM monitors the headlamp switch position. Based on this
input, the BCM may provide voltage to the exterior lamps.
