Cruise Control Systems: Description

Speed control system is electronically controlled. This system does not require engine vacuum. An electronic servo actuates throttle. Major components of speed control system include speed control actuator cable, speed control servo/actuator, Rear Electronic Module (REM), speed control switch, brake pedal position switch, brake pressure switch, anti-lock brake control module and air bag sliding contact. Speed control system is operational only at speeds greater than 30 MPH. Speed control servo/actuator communicates with Anti-Lock Brake System (ABS) module, Powertrain Control Module (PCM) and REM using Standard Corporate Protocol (SCP) bus link. Air bag sliding contact provides electrical interface between steering column wiring and speed control switches in steering wheel.
