Adjustable Pedal System
The adjustable pedal motor directly controls the accelerator pedal through the use of a pinion and worm gear set. The opposite end of the adjustable pedal motor is attached to a cable inside a sleeve, which is connected to another worm gear set located 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 direction of motor rotation determines the direction of pedal movement, forward or rearward.
Adjustable Pedal - without Memory Feature
The pedals can be adjusted using the adjustable pedals control switch with the ignition set to OFF, ON or ACC, regardless of the gear selector position. The adjustable pedal control switch grounds the adjustable pedal motor to drive the pedals either forward or rearward, depending on which direction the switch was pressed, until the switch is released.
Adjustable Pedal - with Memory Feature
Adjustable pedals with memory feature are controlled in 1 of 3 ways:
- Using the adjustable pedal control switch
- Using the memory set switch
- Using the RKE transmitter or passive key
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-CAN. 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 or passive key with the ignition set to OFF, ON or ACC; but the transmission must be in PARK or NEUTRAL. When a RKE transmitter or passive key button is pressed, the transmitted signal is received by the RTM. The RTM sends a message to the DSM over the MS-CAN. The DSM then provides voltage to the adjustable pedal motor to move the pedals to the position programmed into the RKE transmitter or passive key.
The adjustable pedal motor on a system equipped 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.
