Description & Operation

The cruise control system is electronically controlled and vacuum actuated. System components include an Electronic Control Unit (ECU), vacuum pump, actuator, cruise control switch, clutch pedal switch, accelerator pedal switch, cruise indicator light, diode (if equipped), Park/Neutral (P/N) switch (A/T), clutch pedal position switch (M/T), closed throttle position switch, overdrive switch, stoplight switch, throttle position sensor, vehicle speed sensor and A/T control unit.

The system also has self-diagnostic capability. When self-diagnostic mode is activated, each switch and sensor is checked for defects. If cruise control system has been canceled without using a normal cancel method, a code will be set and stored in ECU. Codes can be retrieved to help determine which circuit is malfunctioning.
