Circuit Description

WARNING: This page is about a different car, the 2002 Buick Regal and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

The Body Control Module (BCM) controls the park lamp relay. The BCM grounds the park lamp relay control circuit which energizes the park lamp relay.
