Vehicle Control Module (VCM)
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2000 GMC Yukon, 2000 GMC C3500 HD, 2000 Chevrolet Tahoe, 2000 Chevrolet Suburban, and 2000 Chevrolet Pickup. However, it is still accessible from the selected car via links, so may be relevant.
Vehicle Control Module (VCM) receives vehicle speed information from VSS and disengagement signal from CPP switch (M/T) or brakelight switch. This information is transmitted to cruise control module. Speed information is used to maintain desired vehicle speed. Upon depressing clutch or brake pedal, power to VCM is interrupted, signalling VCM to request cruise control module to disengage cruise function.
