Circuit Description
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The TC2 mode switch is a momentary-contact switch that can be used to limit the traction control function. Each time the TC2 mode switch is pressed, the TC2 switch full traction limited status changes. When the TC2 mode switch is released, voltage on the TC2 mode switch signal circuit is approximately 12 volts. When the TC2 mode switch is pressed, voltage on the TC2 mode switch signal circuit is approximately 0.5 volt.
