Circuit Description

WARNING: This page is about a different car, the 2006 Buick LaCrosse and 2006 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) checks memory to see if it's in the learn mode. If so, the BCM sets this DTC.
