Circuit/System Description

WARNING: This page is about a different car, the 2010 GMC Sierra, 2010 GMC Cab & Chassis Sierra, 2010 Chevrolet Silverado, and 2010 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The adjustable pedals (when RPO AN3 Driver Memory Seat is not used) may only operate while the vehicle is in Park. When the body control module detects the vehicle is NOT in park it will enable the Park Enable PCB Relay by providing power to the relay control circuit. When the relay is enabled the electrical power feed to the adjustable pedals is eliminated. Once the vehicle is shifted into Park the BCM will disable the Park Enable PCB Relay and the electrical power feed to the adjustable pedals is enabled.
