The adjustable pedals system consists of the following components:

The adjustable pedal system is controlled by the adjustable pedal switch or the driver seat module and operation can occur only while the transmission selector lever is in the PARK position. The adjustable pedal assembly is moved forward or backward by a motor, which is fixed to the brake pedal actuator with a drive cable to the accelerator pedal actuator. The adjustable pedal motor is operated by 2 motor control circuits from the adjustable pedal relay. In an inactive state, both of the motor control circuits are closed to the ground contacts within the relay. The relay coils may be energized by the relay control circuits from the driver seat module or the adjustable pedal switch. When a relay coil is energized, the motor control circuit is switched to the battery voltage supply contact. The adjuster motor is bi-directional and the direction of the pedal assembly travel is determined by which of the motor control circuits is closed to battery voltage, while the other remains grounded.

The driver seat module monitors the location of the adjustable pedals using the brake pedal position sensor. The brake pedal position sensor is supplied with 5-volt reference and ground circuits from the driver seat module. The position sensor signal circuit is referenced from ground within the driver seat module. The signal voltage monitored by the driver seat module ranges from 0.39-4.58 volts and is determined by the wiper location on the resistor within the position sensor. The position sensor circuit voltage level is used by the driver seat module to determine the position of the adjustable pedals when storing or recalling memory position settings.
