Circuit/System Description

The instrument cluster illuminates the traction control/stability control-active indicator, traction control off indicator and stability control off indicator for 5 seconds after the ignition is turned ON. The electronic brake control module will request the instrument cluster 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 signal circuit from the traction control switch. When the traction control switch is pressed once, the body control module sends a serial data message to the electronic brake control module to disable the traction control system. When the traction control switch is pressed and held for 5 seconds, the body control module will request the electronic brake control module to disable the electronic stability control. The electronic brake control module will request the instrument cluster to turn the traction control off and stability control off indicator ON to notify the driver of the deactivation.
