The system is operational only at speeds greater than 30 MPH. When ON and SET-ACCEL switches have been pressed, vehicle speed will be maintained until new speed is set, brake pedal is pressed, OFF switch has been pressed, or hazard lights are activated. On vehicles with M/T, a clutch switch disengages the system to prevent engine overspeed when the clutch is operated. System is deactivated when servo pin No. 4 loses continuity to ground (through stoplights) or senses 12 volts from stoplight switch.
TRY AND do A SELF-DIAGNOSTIC TEST
While holding the speed control OFF button, turn ignition switch to ON position. Ensure engine does not start. The speed control indicator on insrtument panel should flash once to indicate successful entry into self-diagnostic mode.
Whithin 5 seconds of entering self-diagnostics, press speed control ON button. Press remaining speed control buttons in the following sequence; ON, RSM, CST and SET/ACCEL. As each button is pressed, speed control indicator will flash. Wait until indicator light goes out to press next button.
After sequence has been completed, the indicator light will flash to indicate pass or fail as follows:
1 flash = Passed self-test.
2 flashes = Brake on/off switch faulty or misadjusted.
3 flashes = Brake deactivation switch or circuit open.
4 flashes = Vehicle speed sensor out of range.
5 flashes = Servo/actuator is defective.
Immediately after a passed results, actuator performs a dynamic test by automatically operating throttle.04-.40" (1-10 mm). Observe throttle movement to witness any sticking of cable or linkage. Ensure throttle returns properly. Turn igntion off
