Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Cruise Control
On models with cruise control, the system is operated by the control module. Control module receives inputs from VSS, servo diaphragm position sensor, cruise control switch and brake release switch. Based on these inputs, control module controls vacuum valves at servo. Control module prevents system engagement at speeds of less than 25 MPH. Control module is not serviceable; if defective, it must be replaced. System faults are stored as codes in control module memory.
