  2. Using 3 new 1.5-volt batteries in series, connect batteries to ISC actuator terminals "D" and "E". DO NOT  connect batteries for more than one second.
  3. With positive side of batteries connected to ISC actuator terminal "D", ensure actuator expands. With positive side of batteries connected to ISC actuator terminal "E", ensure actuator contracts. If any of ISC actuator tests fail, replace lower throttle body.
