Stability/Traction Control Switch

The stability/traction control switch is hardwired to the IPC. The IPC communicates switch status to the ABS module via the HS-CAN. The traction control switch allows the driver to control the AdvanceTrac® system. Traction control system status is indicated by the sliding car OFF icon and the message center in the IPC. The AdvanceTrac® system automatically restores to full functionality when the ignition is cycled from OFF to ON. There are 3 or 4 AdvanceTrac® system modes that can be selected, depending on the vehicle configuration and options.

• AdvanceTrac® enabled (both traction control and ESC functions are active)
• Traction control disabled (ESC function remains active)
• AdvanceTrac® Sport (special calibration to enhance performance characteristics, not available on all vehicles)
• AdvanceTrac® disabled (both traction control and ESC systems are off)

The different modes of the AdvanceTrac® system can only be selected by starting with the AdvanceTrac® enabled. When a mode other than AdvanceTrac® enabled is selected, the sliding car OFF icon in the IPC illuminates. When the switch is pressed a single time, the traction control is disabled (traction control off mode); when the switch is pressed twice while the brake pedal is applied, AdvanceTrac® Sport mode is enabled; and when the switch is pressed and held for at least 5 seconds while the brake pedal is applied, the entire AdvanceTrac® system is disabled.

Pressing the switch once from any of the above-mentioned modes re-enables full AdvanceTrac® system operation. Also, at the start of every ignition cycle, full AdvanceTrac® system operation is present regardless of the mode selected on the previous ignition cycle (unless the vehicle is equipped with launch control and launch control is enabled). The conventional ABS cannot be disabled through the use of the stability/traction control switch.
