5. Turn the power switch off.

B → GO TO DTC CHART 

A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Enter the following menus: Powertrain / EV / Data List / Charge Light Status.
4. Read the value displayed on the Techstream.

   Result

   Tester Display	Condition	Charging Indicator Condition	Normal Condition
   Charge Light Status	Charging connector installed to electric vehicle charger inlet	2 charging indicators illuminate	Valve Check

   OK

   Operation of the charging indicator matches the display of the Data List.

5. Turn the power switch off.
