Circuit/System Description

WARNING: This page is about a different car, the 2008 Isuzu i-370, 2008 Isuzu i-290, 2008 GMC Canyon, and 2008 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.

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