Normal Operation

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.

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 applies 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 removes power from the brake pedal feel simulator cut-off valve solenoid, relieving simulator fluid pressure.

The ABS module provides power to the brake pedal feel simulator cut-off valve solenoid.

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.

Both the brake pedal feel simulator cut-off solenoid valve and brake pedal feel simulator cut-off pressure sensor are internal to the brake pedal feel simulator and cannot be serviced separately. If a new brake pedal feel simulator is needed, a new brake pedal assembly must be installed.

DTC DESCRIPTION TABLE

DTC Description Fault Trigger Conditions
  • C1011:1C - Brake Pedal Feel Simulator Cut-Off Pressure Sensor: Circuit Voltage Out of Range
 If the brake pedal feel simulator cut-off pressure sensor circuits are intermittently shorted to ground, shorted to voltage or have high resistance, this DTC sets.
  • C1011:1F - Brake Pedal Feel Simulator Cut-Off Pressure Sensor: Circuit Intermittent
 If the brake pedal feel simulator cut-off pressure sensor circuits are shorted to ground, shorted to voltage or have high resistance, this DTC sets.
  • C1011:67 - Brake Pedal Feel Simulator Cut-Off Pressure Sensor: Signal Incorrect After Event
 If the test signal produced by the brake pedal feel simulator cut-off pressure sensor is incorrect, this DTC sets.
  • C1012:01 - Brake Pedal Feel Simulator Cut-Off Valve Solenoid: General Electrical Failure
 If the brake pedal feel simulator cut-off valve solenoid circuits are shorted to ground, shorted to power or have high resistance or if the brake pedal feel simulator cut-off valve solenoid is shorted internally, this DTC sets.

This pinpoint test is intended to diagnose the following:
