When the BCM sees the traction control switch input grounded for 5 seconds while the vehicle is stopped and the ignition is ON, it sends a serial data message to the EBCM that tells the EBCM that the traction control switch has been pressed for 5 seconds. The EBCM then disables TCS, while leaving VSES enabled. The EBCM sends a serial data message to the instrument cluster display the Competitive Driving message on the DIC.
