Circuit/System Description

The instrument cluster illuminates the traction control/stability control-active indicator for 5 seconds after ignition ON. The electronic brake control module 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 electronic brake control module 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 monitors the stability control switch. When the traction control switch is pressed once, the body control module will request the electronic brake control module via serial data to disable the traction control. When the traction control switch is pressed for 5 seconds, the body control module will request the electronic brake control module to disable the stability control. The electronic brake control module will request the instrument cluster via serial data to turn the traction control off indicator and stability control off indicator ON to notify the driver of the deactivation.
