Adjustable Pedal - with Memory Feature

Adjustable pedals with memory feature are controlled in 1 of 3 ways:

The pedals can be adjusted using the adjustable pedal control switch with the ignition set to OFF, ON or ACC, regardless of the gear selector position. When the adjustable pedals control switch is pressed, a signal is sent to the DSM 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.

The pedals can be adjusted using the memory set switch with the ignition set to OFF, ON or ACC; but the transmission must be in PARK or NEUTRAL. When one of the memory set positions is recalled by pressing the memory set switch, a signal is sent to the DDM which sends a message to the DSM over the MS-CAN1. The DSM responds by sending voltage to the adjustable pedal motor to move the pedals to the programmed memory position.

The pedals can be adjusted using the RKE transmitter with the ignition set to OFF, ON or ACC; but the transmission must be in PARK or NEUTRAL. When a RKE button is pressed, the transmitted signal is received by the RTM. The RTM sends a message to the BCM over a LIN. The BCM transmits the message to the GWM over the HS-CAN1 and the GWM transmits the message to the DSM over the MS-CAN1. The DSM then provides voltage to the adjustable pedal motor to move the pedals to the position programmed into the RKE transmitter.

The adjustable pedal motor on a system with the memory feature contains a Hall-effect switch which allows the DSM to remember the adjustable pedal position. The DSM monitors the Hall-effect switch and stops sending voltage to the motor when the required pedal position is reached. If the DSM receives a pedal position input from the adjustable pedal 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 the Owner's Literature.

For information on linking a preset memory position to the RKE transmitter, refer to the Owner's Literature.
