Steering Wheel Switch Function

WARNING: This page is about a different car, the 2015 Ford C-Max. However, it is still accessible from the selected car via links, so may be relevant.

Cruise control switch inputs are received by the SASM and sent to the BCM on the Medium Speed Controller Area Network (MS-CAN). The BCM then sends the switch information to the PCM through the gateway module.

Pressing and releasing the ON/OFF switch turns the cruise control system on. Pressing up (SET+) or down (SET-) on the SET switch while the vehicle is traveling at the desired speed activates the cruise control system.

While the cruise control system is active, applying the brake pedal or pressing the CAN/RES switch puts the cruise control system into standby mode. Pressing the CAN/RES switch when the cruise control system is in standby mode causes the vehicle to accelerate to the last set speed. Resume does not function if the ON/OFF switch is pressed, the ignition is cycled OFF, or if the current vehicle speed is below the minimum operational speed.

Pressing the SET switch up or down while in the active mode increases or decreases the maintained vehicle speed by 1.6 km/h (1 mph) per press. If the respective switch is pressed and held, the vehicle speed continues to accelerate or decelerate until the switch is released.

Pressing and releasing the ON/OFF switch while the cruise control is active, or the ignition is cycled OFF, turns the cruise control system off.
