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 internal fault detection of the electronic compass module is handled by the instrument panel cluster (IPC). The compass information is sent to the IPC via 2 discreet inputs from the electronic compass module. The IPC displays compass information in the driver information center (DIC). The DIC displays 2 dashes (- -) when the IPC looses connection with the electronic compass module.
