C1011 FORD Description

The brake pedal feel simulator cut-off solenoid valve and brake pedal feel simulator cut-off pressure sensor are located within the brake pedal feel simulator, which is attached to the brake pedal assembly. The ABS module will apply a Pulse Width Modulated (PWM) ground signal to the brake pedal feel simulator cut-off solenoid valve to increase the resistance felt when the driver applies the brake pedal. The ABS module uses input from the brake pedal feel simulator cut-off valve pressure sensor to verify that the brake pedal feel simulator cut-off solenoid valve is functioning properly. If the ABS module detects a fault with a brake system component that would adversely affect brake-by-wire operation, the module will remove power from the brake pedal feel simulator cut-off valve solenoid, relieving simulator fluid pressure. The ABS module provides the brake pedal feel simulator cut-off pressure sensor a 5-volt reference voltage. The brake pedal feel simulator provides a signal voltage proportional to the fluid pressure in the brake pedal feel simulator cut-off device to the ABS module. The ABS module provides a signal return for brake pedal feel simulator cut-off pressure sensor.
