System Operation Check

  1. Drive vehicle at speeds greater than 25 MPH. Place cruise control main switch in ON position. Press SET button once and release. Remove foot from accelerator pedal. Vehicle should maintain set speed. If vehicle speed does not maintain set speed, go to CRUISE CONTROL INOPERATIVE/MALFUNCTIONING  or CRUISE CONTROL INOPERATIVE/MALFUNCTIONING (USING TESTER J42958)  under SYMPTOM TESTS.
  2. Hold slider switch in R/A position until vehicle speed increases 4-5 MPH. Vehicle should accelerate and maintain new set speed. Press SET button until vehicle speed decreases 4-5 MPH. Vehicle should decelerate and maintain new set speed. If vehicle operates as specified, go to next step. If vehicle does not operate as specified, go to CRUISE CONTROL INOPERATIVE/MALFUNCTIONING  or CRUISE CONTROL INOPERATIVE/MALFUNCTIONING (USING TESTER J42958)  under SYMPTOM TESTS.
  3. Depress brake pedal slightly. Cruise control system should disengage. If operation is as specified, go to next step. If operation is not as specified, go to CRUISE CONTROL INOPERATIVE/MALFUNCTIONING  or CRUISE CONTROL INOPERATIVE/MALFUNCTIONING (USING TESTER J42958)  under SYMPTOM TESTS.
  4. Move slider switch to R/A position once and release. Vehicle should accelerate and maintain previously set speed. Tap-up R/A switch (less than 1/2 of a second). Vehicle speed should increase one MPH. Tap-down SET button (less than 1/2 of a second). Vehicle speed should decrease one MPH. If operation is as specified, go to next step. If operation is not as specified, go to CRUISE CONTROL INOPERATIVE/MALFUNCTIONING  or CRUISE CONTROL INOPERATIVE/MALFUNCTIONING (USING TESTER J42958)  under SYMPTOM TESTS.
  5. Simultaneously press SET button and R/A switch. Cruise control system should disengage, but retain previously set speed in memory. Place cruise control main switch in OFF position. Cruise control system should disengage, and set speed should be erased from memory. If vehicle operates as specified, system is okay at this time. If vehicle does not operate as specified, go to CRUISE CONTROL INOPERATIVE/MALFUNCTIONING  or CRUISE CONTROL INOPERATIVE/MALFUNCTIONING (USING TESTER J42958)  under SYMPTOM TESTS.
