Traction Control Switch

Unlike the standard anti-lock control system, the traction control system can be deactivated through the traction control switch. On vehicles equipped with a navigation system, the switch is part of the Front Controls Interface Module (FCIM) module but is hard-wired to the IC. When the switch is pressed, a signal is sent to the IC indicating a request to deactivate the traction control system.

On vehicles not equipped with a navigation system, the switch is part of the HVAC module, but still has a separate hard-wired circuit connected to the IC. When the switch is pressed, a signal is sent to the IC indicating a request to deactivate the traction control system.

When the IC receives the disable signal, a message is sent over the HS-CAN bus indicating a request has been made to deactivate the system and illuminates the traction control OFF indicator (sliding-car OFF icon). After receiving this message, the ABS module and PCM will ignore any traction events until the switch is pressed again or the ignition key is cycled.

The AdvanceTrac® system cannot be disabled when a MyKey™ -restricted key is in use that has the AdvanceTrac® always-on feature configured to "on". If an attempt is made to disable the AdvanceTrac® system while a MyKey™ -restricted key is in use, ADVTRAC ON MY KEY SETTING will display in the IC message center.
