Circuit Description
The adjustable pedal system will be disabled by the adjustable pedal module anytime the transmission selector lever is not in the park position while the ignition is on. This feature is controlled by the body control module (BCM) through the adjustable pedal inhibit circuit. While the system is being disabled the BCM supplies battery voltage to the adjustable pedal module through the adjustable pedal inhibit circuit. When the adjustable pedal system is enabled by the body control module the adjustable pedal inhibit circuit will be at 0 volts.
