Circuit Description

WARNING: This page is about a different car, the 2005 Buick LaCrosse and 2005 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 wire inputs from the electronic compass module. The IPC displays compass information in the driver information center (DIC). The IPC sets DTC B0934 when either compass sensor circuit is shorted to battery.
