Circuit/System Description

WARNING: This page is about a different car, the 2010 GMC Terrain and 2010 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster illuminates the traction control/stability control-active indicator, winter indicator and stability control off indicator for 5 s after ignition ON. The electronic brake control module (EBCM) will request the instrument cluster via serial data to turn the traction control/stability control-active indicator ON (flashing) when the system is in traction control or stability control mode. When the EBCM detects a fault it sends a serial data message to the instrument cluster commanding the traction control/stability control-active indicator ON.

The body control module (BCM) monitors the stability control switch. When the stability control switch is pressed once, the BCM will request the EBCM via serial data to disable the traction control. When the stability control switch is pressed for 5 s, the BCM will request the EBCM to disable the stability control. The EBCM will request the instrument cluster via serial data to turn the winter indicator and stability control off indicator ON to notify the driver of the deactivation.
