Circuit Description
WARNING: This page is about a different car, the 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
When the heated seat system is activated, the body control module (BCM) controls the heated seat operation through the heated seat relay control circuit and the heated seat relay. The relay energizes and applies battery positive voltage to the seat heater elements. The circuit that generated this diagnostic trouble code (DTC) is the heated seat relay control circuit that is wired between the BCM and the heated seat relay.
