Circuit Description

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The traction control switch is a momentary-contact, normally-open switch that can be used to disable the TCS. Each time the traction control switch is pressed, the TCS enabled/disabled status changes. When TCS is disabled, the EBCM illuminates the traction off indicator by opening the service traction control signal circuit.
