Circuit/System Description

WARNING: This page is about a different car, the 2008 GMC Yukon XL and 2008 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.

The wheel speed sensor receives a 12-volt power supply voltage from the electronic brake control module (EBCM) and provides an output signal to the EBCM. As the wheel spins, the wheel speed sensor sends the EBCM a DC square wave signal. The EBCM uses the frequency of the square wave signal to calculate the wheel speed.
