  2. Turn the ignition switch to the ON position (Engine off).
    NOTE:
    • If engine starts and runs, perform the following steps while idling engine.
  3. Prepare the output state control for actuators or relays that you are inspecting.
  4. Vibrate the actuator or relay with your finger for 3 s  after output state control is activated.
    • If variable click sound is heard, check for poor connection and/or poorly mounted actuator or relay.
