Normal Operation and Fault Conditions
The stability-traction control disabled indicator (sliding car OFF icon) in the IPC provides traction control system status to the driver. When the driver deactivates the traction control, the IPC sends a message to the ABS module over the HS-CAN indicating the driver has requested the traction control to be disabled. The ABS module continues to monitor for excessive wheel spin, but no longer takes any action when a traction event is detected. After receiving the traction control status message from the IPC, the ABS module sends a message back to the IPC over the HS-CAN to illuminate the stability-traction control disabled indicator (sliding car OFF icon). The IPC responds by illuminating the stability-traction control disabled indicator (sliding car OFF icon). The traction control system remains deactivated until the driver changes the traction control state in the message center or until the ignition is cycled.
