Stability/Traction Control Switch

Unlike the standard anti-lock control system, the traction control system can be deactivated through the traction control switch. The switch is part of the Front Controls Interface Module (FCIM) module but is hardwired 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 stability/traction control OFF indicator (sliding-car OFF icon). After receiving this message, the ABS module and PCM will ignore any stability or 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. For information about MyKey™, refer to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) .

Stability/Traction Control Indicator (Sliding-Car Icon) and Stability/Traction Control OFF Indicator (Sliding-Car OFF Icon) 

Status of the traction control system is indicated by a traction control indicator (sliding-car icon) and a traction control OFF indicator (sliding-car OFF icon) located in the IC  (or message center if equipped). When the driver disables the traction control system through the use of the traction control switch, the sliding-car OFF icon will illuminate solidly. When one or more of the systems is currently active, the sliding-car icon will flash, and when the system is disabled due to DTCs being present in the ABS module, the sliding-car icon will illuminate. In some cases, the sliding-car icon will illuminate in conjunction with the yellow ABS warning indicator.

If the traction control system has been disabled through the traction control switch, the system will reactivate when the driver presses the switch again or the ignition switch is cycled.
