Base Cluster
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.
Press and hold the season odometer reset for greater than 3 seconds. If the vehicle is in PARK the instrument panel cluster (IPC) will send a class 2 message to the body control module (BCM). Upon receipt of this class 2 message the IPC illuminates the program mode indicator in the message center. This indicator remains illuminated until the IPC receives a class 2 message from the BCM to turn this indicator off or the IPC receives a class 2 message from the powertrain control module (PCM) indicating vehicle speed is present.
