Circuit/System Description

WARNING: This page is about a different car, the 2010 GMC Canyon and 2010 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.

The driver may disable the Traction Control System (TCS) by pressing the traction control switch. The body control module (BCM) supplies a 12 V signal on the traction control signal circuit. When the traction control switch is pressed, this voltage signal is grounded.
