Stability/Traction Control Switch
Unlike the standard anti-lock control system the EOTC system can be deactivated by the driver through the stability/traction control switch. The switch is hard wired to the PCM and when pressed sends a ground signal to the module. The PCM then sends a message over the HS-CAN bus to the IC indicating that the driver has requested that the system be deactivated. When the IC receives this message it illuminates the stability/traction control indicator "sliding-car icon" and sends a message to the Lighting Control Module (LCM) along the Standard Corporate Protocol (SCP) network. Once the LCM has received the message, it illuminates the LED in the stability/traction control switch. The PCM will ignore any traction control events until the driver presses the switch again or the ignition key is cycled.
