Service Traction System
WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
The IPC illuminates the service traction system indicator in the message center when the electronic brake control module (EBCM) detects a malfunction in the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination.
