Adjustable Pedals Description and Operation

Adjustable Pedals System Components

The adjustable pedals system consists of the following components:


• The adjustable pedals switch

• The memory seat control module

• The adjustable pedals assembly

• The adjustable pedal position sensor


Adjustable Pedals System Operation

The adjustable pedals are not operable when the cruise control is engaged.

The adjustable pedal system is controlled by the memory seat module. The adjustable pedals are moved forward or backward by a motor which is fastened to the brake pedal assembly with drive cables to the brake and accelerator pedal actuators.

The adjuster motor is controlled by the memory seat control module through two motor control circuits. In an inactive state both control circuits are closed to ground within the module. The memory seat control module drives the adjuster motor in the forward or rearward direction by closing the appropriate control circuit to battery voltage. The adjuster motor is bidirectional and the direction of the pedal assembly travel is determined by which of the motor control circuits is switched to battery voltage while the other remains grounded.

The adjustable pedals forward and rearward switches are inputs to the module. Battery voltage is supplied to the switch from the memory seat control module. When the switch is operated to the forward or rearward direction the forward or rearward switch signal circuit is closed to the battery voltage circuit. Battery voltage on a switch signal circuit indicates to the memory seat control module that the switch is active.

The memory seat control module monitors the locations of the adjustable pedals using the adjustable pedals position sensor. The position sensor is supplied with a 5 V reference and ground circuit from the memory seat control module. The position sensor signal circuit is referenced from ground within the module. The position sensor signal circuit voltage levels are used by the memory seat control module to determine the positions of the adjustable pedals when storing or recalling memory position settings. Anytime adjustable pedal system components are replaced, including the memory seat control module, the system will not operate until the calibration procedure has been performed.
