Circuit/System Description

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The adjustable pedals 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 memory seat module (MSM) controls the adjustable pedals motor by applying battery voltage to one of the outputs and ground to the other. The adjustable pedals motor is bidirectional and the direction of the pedal assembly travel is determined by which of the motor control circuits is switched to battery positive voltage while the other is grounded. The adjustable pedals forward and rearward switches are inputs to the MSM. The MSM supplies the switch assembly battery voltage. When the switch is operated to the forward or rearward direction, battery positive voltage is applied to the forward or rearward switch signal inputs.
