Cruise Control Systems: Description

WARNING: Vehicles are equipped with Supplemental Inflatable Restraint (SIR) system. Before attempting ANY repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in appropriate AIR BAG RESTRAINT SYSTEMS article.

Cruise control system is completely electronic, and does not require vacuum or a vacuum servo motor. To control throttle movement, a cable from cruise control module pulls on the accelerator linkage at the accelerator pedal.

Cruise control system consists of a cruise control module, cruise control switches, brake release switch, Supplemental Inflatable Restraint (SIR) coil assembly and Powertrain Control Module (PCM). See COMPONENT LOCATIONS .

NOTE: On M/T models, PCM interprets engine speed to calculate when clutch has been depressed. Separate clutch release switch has been eliminated.

Cruise control system can be disengaged by using cruise control switch, depressing brake or clutch (M/T) pedal or shifting out of Drive (A/T) gear position. PCM will automatically disengage cruise control system if vehicle speed is less than 25 MPH or more than 100 MPH. PCM will also automatically disengage cruise control system if it detects a circuit or component failure, traction control is activated (on some models) or engine coolant temperature is more than 244°F (118°C).
