Pedal Positioning Module: Description and Operation

Adjustable Pedals
Expedition and Navigator are equipped with an adjustable brake pedal. Using the adjustable pedal switch, located on the LH side of the instrument panel below the headlamp switch, the driver can adjust the brake and accelerator pedals for a more comfortable driving position.

Driver Seat Module The adjustable pedals are controlled by the Driver Seat Module (DSM) only when the vehicle is equipped with the programmable/recall memory option (Navigator only).

The DSM system consists of the following components:
^ DSM
^ Adjustable pedals
^ Adjustable pedals switch
^ Memory set switch
^ Driver memory seat switch
^ Memory mirror switch
^ Front vertical seat motor
^ Rear vertical seat motor
^ Driver horizontal seat motor
^ Left heated memory mirror
^ Right heated memory mirror
^ Remote Anti-Theft Personality (RAP) module

The DSM incorporates multiple functions into one module and offers diagnostics to easily locate and repair concerns affecting the subsystems that it controls.

The DSM constantly monitors the systems under its control and reports a concern in the form of Diagnostic Trouble Codes (DTCs). A DTC can be retrieved with the Worldwide Diagnostic System (WDS) or equivalent scan tool through the communications link.

Adjustable Pedal Operation The adjustable pedals, with memory feature, (Navigator only) are controlled by the DSM and are operational all the time, ignition switch ON, or OFF. Using the adjustable pedal switch, the driver can adjust the adjustable pedals forward, and rearward. The DSM will power the adjustable pedals until the switch is released, or until the travel limit is reached.

Memory Adjustable Pedal Operation The memory adjustable pedal feature allows the driver to program a personalized pedal position that can be recalled using the memory switches or remote keyless entry transmitters. There are three memory settings possible. The outside rearview mirror and power driver seat positions are also stored and recalled with the power adjustable pedal positions.

Programming Adjustable Pedal Positions Programming adjustable pedal positions can be accomplished by doing the following:
^ An adjustable pedal position can be stored at any time. To store the adjustable pedal position to memory, the driver must move the pedals to the preferred position using the adjustable pedal switch. The driver must then depress the memory SET switch, activating the memory SET switch Light Emitting Diode (LED). Within 5 seconds (before the LED goes out) the driver must select a memory position. Memory no. I is selected by depressing the 1 switch. Memory no. 2 is selected by depressing the 2 switch.
^ If no memory switch input is received within the 5 second time limit, the operation is aborted and the memory SET switch LED is turned OFF. If one of the following inputs is received during the 5 second programming limit, the operation is aborted and the memory SET switch LED is turned OFF:
- Adjustable pedal switch
- Power driver seat switch
- Power outside rearview mirrors switch
- Memory SET switch.

Recalling a Stored Adjustable Pedal Position
Once the driver has stored a preferred adjustable pedal position, the driver can recall the setting by depressing the corresponding memory switch, or by using a programmed remote keyless entry transmitter. Recalling a stored adjustable pedal position can be accomplished by doing the following:
^ The driver can recall a preferred adjustable pedal position by depressing one or both of the memory recall switches. Pressing memory switch 1 will initiate a recall of the adjustable pedal position stored in memory no 1. Pressing memory switch 2 will initiate a feel of the adjustable pedal position stored in memory no. 2. Pressing both memory no. 1, and memory switch 2, will initiate a recall of the adjustable pedal position stored in memory no. 3.
^ A remote keyless entry transmitter (RAP module interface) can be used to recall previously set memory positions. The remote keyless entry transmitters are manufactured with an assigned personality number (1, 2, or 3) and are so designated on the back of the remote keyless entry transmitter case The remote keyless entry transmitter assigned with personality 1 is capable of only recalling memory position 1. Similarly, the remote keyless entry transmitters assigned with personalities l and 2, can only recall memory positions 1 and 2, respectively.
^ Memory recall occurs when the UNLOCK switch is pressed on the remote keyless entry transmitters. A second press of the UNLOCK switch, which unlocks the passenger doors. does not initiate a memory recall.
^ A memory recall in progress does not prohibit the initiation of another memory recall; the most recently requested memory recall will be executed.
