Traction Control Switch
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Unlike conventional ABS, the traction control portion of the AdvanceTrac® can be deactivated by the driver through the use of the traction control switch. The switch is hardwired to the IPC. When pressed, the switch sends a ground signal to the IPC. The IPC then sends a message over the HS-CAN bus indicating that the driver has requested that the system be deactivated and illuminates the sliding-car OFF icon. Once disabled, the system remains in that state until the driver presses the switch again or the ignition key is cycled.
