Cruise Control Engaged
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 cruise control module grounds the cruise engaged signal circuit when cruise control is engaged. The PCM monitors the cruise engaged signal circuit in order to determine when the cruise control is engaged. The PCM sends a class 2 message indicating that the cruise control is engaged to the instrument panel cluster (IPC ) (Buick Only). The IPC illuminates the cruise indicator. The cruise control module, cruise cancel signal circuit, is a circuit used by the PCM to inhibit cruise control when conditions inconsistent with cruise operation are present.
