Ford Fusion: Steering Wheel and Column Electrical Components / Steering Wheel and Column Electrical Components - Overview. Description and Operation
Steering Column Switches Overview
The
steering column switches are located on and around the steering column.
This enables the driver to control various vehicle functions and remain
focused on driving. Depending on vehicle options, the steering column
switches consist of:
-
Multifunction switch - mounted on the left side of the SCCM and can be serviced separately. The SCCM is a module that requires Programmable Module Installation (PMI).
-
Steering wheel switches - mounted on the front of the
steering wheel and can be serviced separately from the steering wheel.
-
Wiper and washer switch - mounted on the right side of the SCCM and can be serviced separately.
The steering column switches interface with other modules and components on the vehicle through the SCCM, which communicates on the High Speed Controller Area Network 2 (HS2-CAN).
Push Button Start Ignition System Overview
The push button start ignition system uses the following components:
-
Ignition switch (push button start)
-
BCM
-
Stoplamp switch
-
Front PATS antenna
-
Passive key
-
RTM
-
PCM
The available push button start modes are:
To
achieve any ignition mode other than OFF, the passive key must be
present inside the vehicle. The driver does not need to perform any
actions on or with the passive key to operate the push button start
system. Pressing the ignition switch causes the BCM to activate the front PATS antenna. The front PATS
antenna then sends out a Radio Frequency (RF) signal to the passive
key. The passive key responds by transmitting a Radio Frequency (RF)
signal to the RTM. The RTM then sends a CAN message to the BCM that the passive key has responded. Based on the ignition switch and stoplamp switch inputs, the BCM activates the appropriate ignition mode.
Push Button Start System Message Center Messages
The
message center provides instruction for operating the push button start
system. These messages pertain to the push button start system:
-
Press brake to start — Momentarily displays when the
ignition switch is pressed without the brake pedal being applied.
-
Key not detected — Displays if the passive key is not detected by the RTM
while attempting to start the vehicle or enter ON mode. If this message
is observed with the passive key located inside the vehicle,
Refer to: Passive Anti-Theft System (PATS) (419-01 Passive Anti-Theft System (PATS) - Vehicles With: Push Button Start)
.
Heated Steering Wheel Overview
The heated steering wheel system consists of the following components:
-
Steering wheel heater elements (part of steering wheel)
-
Steering wheel temperature sensor (part of steering wheel
-
HSWM
-
FDIM
