Cruise Control

On models equipped with cruise control, the system is operated by the ECM. ECM receives inputs from Vehicle Speed Sensor (VSS), servo diaphragm position sensor, cruise control switch and brake release switch. Based on these inputs, ECM controls position of cruise control stepper motor. ECM prevents system engagement at speeds of less than 25 MPH. ECM is not serviceable; if defective, it must be replaced. A system fault is stored as a DTC in ECM memory.
