DESCRIPTION AND OPERATION

Adjustable Pedals

Overview

The adjustable pedal feature uses an electrical motor to adjust the brake and accelerator pedal positions forward and rearward to increase driver comfort. Two adjustable pedal systems are available; one that is connected to the memory feature option and one that is not connected to the memory feature option.

 Module Network Input Messages: Adjustable Pedals

Adjustable Pedal System

The adjustable pedal motor directly controls the accelerator pedal through the use of a pinion and worm gear set. The other end of the motor is attached to a cable inside a sleeve, which is connected to another worm gear set on the brake pedal for the adjustment of the brake pedal. When the motor rotates, the worm gear set on the accelerator pedal and the worm gear set on the brake pedal both rotate simultaneously. The motor direction of rotation determines the direction of pedal movement, forward or rearward.

Adjustable Pedals without Memory Feature

The adjustable pedals without memory feature are controlled by the SCCM and the adjustable pedals control switch.

Adjustable Pedals with Memory Feature

The adjustable pedals with memory feature are controlled by the SCCM, BCM and DSM. The pedals can be adjusted in 3 different ways:

• Using the adjustable pedals control switch.
• Using the memory set switch, when associated with the seat/mirror/pedal position programmed into the memory that is recalled using the memory set switch.
• Using the RKE feature, when associated with a memory setting, will recall the seat/mirror/pedal positions associated with that setting

The SCCM monitors the adjustable pedal motor and circuits for concerns. If a concern is detected, the SCCM is capable of setting DTCs.

Operating with Adjustable Pedals Control Switch

The pedals can be adjusted using the adjustable pedals control switch with the ignition in OFF, ON, ACC or RUN, regardless of the gear selector position. When the adjustable pedals control switch is pressed, a signal is sent to the SCCM which then sends voltage to the adjustable pedal motor. The motor then drives the pedals either forward or rearward (depending on which direction the switch was pressed) until the switch is released.

Operating with Memory Set Switch

The pedals can be adjusted using the memory SET switch with the ignition in OFF, ON, ACC or RUN; but the gear selector must be in the PARK position. When one of the memory set positions is recalled by pressing the memory set switch, the DSM senses continuity to ground through the memory set switch circuit and sends a message to the BCM over the MS-CAN. The BCM acts as a gateway module and transmits the message to the SCCM over the HS-CAN. The SCCM then provides voltage to the adjustable pedal motor to move the pedals.

The SCCM monitors the Hall-effect sensor in the adjustable pedal motor and stops sending voltage to the motor when the required pedal position is reached. If the SCCM receives a pedal position input from the adjustable pedals control switch during a memory position recall, the module stops the memory recall and responds to the new pedal position input.

For information on setting and recalling a memory pedal position, refer to Memory Position Programming in Section 501-10.

Operating with Remote Keyless Entry (RKE)

The pedals can be adjusted using the RKE transmitter with the ignition in OFF, ON, ACC or RUN; but the gear selector must be in the PARK position. When the RKE button is pressed on the IA key, the transmitted signal is received by the TPM module. The TPM module sends a message to the RFA along a hard wired LIN. The RFA then sends the message to the BCM over the MS-CAN. The BCM acts as a gateway module and transmits the message over the HS-CAN to the SCCM. The SCCM then provides voltage to the adjustable pedal motor to move the pedals to the position programmed into the IA key.

The SCCM monitors the Hall-effect sensor in the adjustable pedal motor and stops sending voltage to the motor when the required pedal position is reached. If the SCCM receives a pedal position input from the adjustable pedals control switch during a memory position recall, the module stops the memory recall and responds to the new pedal position input.

Diagnostic Routines

Pinpoint Test A: The Adjustable Pedals Only Move in 1-Second Intervals

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 127, Adjustable Pedals for schematic and connector information.

Normal Operation and Fault Conditions

The SCCM uses a Hall-effect sensor integral to the motor to identify the current pedal position. The SCCM sends a reference voltage along the sensor feed circuit, through the Hall-effect sensor and back to the SCCM along the signal return circuit.

When one or more of the following DTCs set, the adjustable pedals enter a "jog mode". The memory system recall will not function from either the memory set switch or the RKE transmitter while the pedals are in jog mode. The motor moves the pedals for only one second regardless of the length of time the adjustable pedals control switch is actually pressed.

DTC Fault Trigger Conditions

PINPOINT TEST A: THE ADJUSTABLE PEDALS ONLY MOVE IN 1-SECOND INTERVALS

Pinpoint Test B: The Adjustable Pedals are Inoperative or Do Not Operate Correctly - Using the Adjustable Pedals Control Switch

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 127, Adjustable Pedals for schematic and connector information.

Normal Operation and Fault Conditions

The SCCM receives fused battery voltage from the BCM.

Pressing the adjustable pedals control switch causes the SCCM to send current along one circuit to the adjustable pedal motor. The current returns to the SCCM along another circuit and is grounded through the SCCM, this moves the pedals in the desired direction. Pressing the adjustable pedals control switch in the opposite direction reverses the current flow through the circuits and moves the pedals in the opposite direction.

DTC Fault Trigger Conditions

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 127, Adjustable Pedals for schematic and connector information.

Normal Operation and Fault Conditions

Pressing the memory SET switch causes the DSM to communicate the desired pedal position to the BCM on the MS-CAN. The BCM acts as a gateway module and relays the message to the SCCM along the HS-CAN. The SCCM sends current to the adjustable pedal motor to move the pedals to the required position.

Pressing the unlock button on the RKE transmitter sends a radio frequency signal to the TPM module. The TPM module sends a message to the RFA module along a dedicated LIN. The RFA module then sends a message to the BCM along the MS-CAN. The BCM acts as a gateway module and relays the message to the SCCM along the HS-CAN. The SCCM sends current to the adjustable pedal motor to move the pedals to the position programmed to the key.

PINPOINT TEST C: THE ADJUSTABLE PEDALS ARE INOPERATIVE OR DO NOT OPERATE CORRECTLY - USING THE MEMORY SET SWITCH OR THE RKE TRANSMITTER
