Charging Timer Switch Circuit [10/2013 - ]: Procedure

  1. READ VALUE USING TECHSTREAM (CHARGING TIMER SW) 
    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Enter the following menus: Powertrain / Plug-in Control / Data List / Charging Timer SW.
    4. Read the value displayed on the Techstream.
      Tester Display Measurement Item/Range Normal Condition
      Charging Timer SW Charging timer switch status/
      ON or OFF      		 ON: Charging timer switch operated
      OFF: Charging timer switch not operated

      OK

      The Data List values change in accordance with the status of charging timer switch.

    5. Turn the power switch off.
