Circuit Description
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) monitors the ignition 0 voltage circuit when the ignition switch is in either the ON position or the OFF position. If the IPC senses that the ignition 0 voltage circuit is low for greater than 3 seconds, DTC B1369 is set.
