Circuit/System Description
The traction control switch for the CTS-V is located on the steering wheel. When the switch is pressed, the signal circuit from the body control module (BCM) is pulled low through a series of resisters indicating the traction control disable command. In response to this signal, the BCM sends a serial data message to the electronic brake control module (EBCM) to disable the traction control system. When the traction control switch is pressed and held for 5 seconds, the BCM sends a serial data message to the EBCM commanding it to disable the stability control. After the EBCM disables the stability control, it sends a serial data message to the instrument cluster requesting it to turn the traction control indicator OFF and turn stability off indicator ON.
