Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Description
Voltage to the adjustable pedal switch is supplied through the park enable relay while in a de-energized state. The park enable relay is controlled by the body control module (BCM) through a high side drive control circuit and will be energized whenever the ignition is in the accessory, run, or crank positions and the transmission is in reverse or the cruise control is engaged. The adjustable pedals switch controls the adjustable pedals relay by applying battery voltage to one of the coils. In an inactive state both of the relay switch contacts are closed to ground and when one of the relay coils is energized its switch contact is closed to battery voltage.
