Stability/Traction Control Switch: Notes

Unlike the standard anti-lock control system, the traction control system and Electronic Stability Control (ESC) system can be deactivated (at the same time) through the stability/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 Instrument Cluster (IC). When the switch is pressed, a signal is sent to the IC  indicating a request to deactivate the stability/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 stability/traction control system.

When the IC  receives the disable signal, a message is sent over the High Speed Controller Area Network (HS-CAN) bus indicating a requesting has been made to deactivate the system and illuminates the stability/traction control indicator "sliding-car icon". After receiving this message, the ABS module and PCM will ignore any stability or traction events until the switch is pressed again, the ignition key is cycled or the vehicle speed reaches or exceeds 70 km/h (43 mph). Once the vehicle speed reaches or exceeds 70 km/h (43 mph), the stability control system will re-activate but the indicator will remain illuminated.
