Action Taken When the DTC Sets

WARNING: This page is about a different car, the 2008 GMC Sierra, 2008 GMC Cab & Chassis Sierra, 2008 Chevrolet Silverado, and 2008 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The object alarm module commands the telltale red indicator ON.
The object alarm module sends a serial data communication message to the instrument panel cluster (IPC) to display SERVICE PARK ASSIST message in the driver information center (DIC), and the chime will sound.
