Components 1. SET - switch2. RES + switch3. SCC switch4. CANCEL switch5. CRUISE switch
Inspection [Measuring Resistance] 1. Disconnect the cruise control switch connector from the control switch. 2. Measure resistance between terminals on the control switch when each function switch is ON (switch is depressed).
Replacement 1. Discharge refrigerant from refrigeration system. 2. Replace any faulty tubes or hoses. Cap the open fittings immediately to keep moisture or dirt out of the system. 3. Tighten the bolt or nut joint to the specified torque.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the intake actuator connector. 3. Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4. Verify that the intake actuator operates to the recirculation position when connected in reverse.
