Circuit Description
WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
The vehicle stability control switch allows the vehicle operator to modify the traction and ride characteristics of the vehicle. The Engine Control Module (ECM) supplies a 5 V reference voltage, through the 5 V reference voltage circuit, to the vehicle stability control switch. The 5 V reference voltage induces current to flow through a series of resistors in the switch to the switch ground circuit. The ECM monitors the reference voltage through a discrete vehicle stability control switch signal circuit.
