Circuit/System Description

WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

The driver information center (DIC) switch is controlled by the IPC. Power and ground is provided to the DIC from the instrument panel cluster. The IPC also provides power to the DIC switch and the DIC switch signal circuit is pulled up to battery voltage in the IPC. The DIC switch input to the DIC is grounded when a switch is activated. The IPC monitors the DIC switch signal circuit to determine the DIC switch inputs.
