Circuit Description
WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) momentarily illuminates the stabilitrak indicator during the IPC bulb check when the ignition is turned ON. When the traction control switch is pressed, the BCM sends a serial data message to the IPC to illuminate indicating traction is disabled. When the EBCM detects a fault, a serial data message is sent to the IPC to illuminate the indicator.
