Set Function Check

  1. Turn ignition on. Check for battery voltage between ground and breakout box pin No. 2. Depress SET button. Ensure no voltage is present between ground and breakout box pins No. 1 and 3. If voltages are not as specified, disconnect cruise control switch connector. Ensure voltage is present between ground and switch connector terminal No. 7. If all voltages are as specified, go to step  3 . If all voltages are not as specified, go to next step.
  2. Turn ignition off. Disconnect cruise control switch connector. Measure resistance between load side of fuse No. 22 and switch connector terminal No. 7. If resistance is greater than one ohm, repair wiring. If resistance is not greater than one ohm, go to next step.
  3. Hold switch in SET position. Measure resistance between switch terminals No. 7 and 10. Hold switch in ON/OFF position. Measure resistance between switch terminals No. 7 and 9, then between terminals No. 7 and 8. If any reading is greater than one ohm, replace switch. If readings are less than one ohm, measure resistance between switch connector and breakout box terminals. See CRUISE CONTROL FUNCTION SWITCH CONNECTOR/BREAKOUT BOX RESISTANCE  table. If any readings are greater than one ohm, repair wiring. If any readings are less than one ohm, replace cruise control module.
