B2597 CADILLAC Description
The Traction Control and Active Handling indicator is controlled by the instrument cluster via serial data messages from the Electronic Brake Control Module (EBCM). When the Body Control Module (BCM) sees the traction control switch input grounded through the momentary traction control switch, it sends a serial data message to the EBCM that tells the EBCM that the traction control switch has been pressed. The EBCM then disables TCS and VSES. The EBCM sends a serial data message to the instrument cluster to turn the Traction Control and Active Handling indicator ON and display the Traction System Off message or the Traction/Active Handling Off message ( on the DIC.
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. The Traction Control and Active Handling indicator remains OFF.
