Circuit/System Description

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

The body control module (BCM) controls the R6 IGN relay through the run/crank ignition 1 voltage circuit by applying voltage to the circuit. The R6 IGN relay is energized when the ignition switch is in ON or START or when a remote start is requested.
