  HINT:
  
  The electric vehicle charger assembly cannot be put into check mode.
CHECK FREEZE FRAME DATA
1. If a DTC is present, select it in order to display its freeze frame data.
2. Read the freeze frame data recorded when the DTC was stored.
CHECK TIME STAMP
HINT:

By checking Time Stamp, the time and order in which DTCs were stored in an ECU can be checked.
1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Health Check.
5. Perform the following steps when the data setting screen is displayed.
6. Select the systems for which to perform Health Check and check for time stamp data.
  Selectable items:
  - Powertrain
  - Chassis
  - Body
  - Store All Data
7. Select "Yes" when "Do you want to store time stamp data?" is displayed.
  HINT:
  
  If "Yes" is not selected, time stamp data will not be stored.
8. After Health Check has completed, select "Time Stamp Data" to display the Time Stamp screen.
9. Select the desired system from the drop-down list on the bottom of the Time Stamp screen.
10. Check the order and time which DTCs were stored for the selected system.
CHECK FOR DTCS (SYSTEMS EXCEPT PLUG-IN CHARGE CONTROL)
HINT:

The electric vehicle charger assembly maintains communication with other computers, including hybrid vehicle control ECU, motor generator control ECU, battery ECU assembly, ECM and combination meter assembly. Therefore, if the electric vehicle charger assembly outputs a warning, it is necessary to check and record the DTCs of all systems.
1. If DTCs are present, check the relevant systems.
  HINT:
  
  If DTCs for the CAN communication system are present in addition to other DTCs, first troubleshoot and repair any malfunctions in the CAN communication system.
CLEAR DTCS (PLUG-IN CONTROL)
NOTE:
Clearing the DTCs will also clear the freeze frame data.
1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Plug-in Control / Trouble Codes.
  Powertrain > Plug-in Control > Trouble Codes
5. Clear DTCs and freeze frame data.
  Powertrain > Plug-in Control > Clear DTCs
CLEAR PERMANENT DTC
OUTLINE
1. After clearing current DTCs using the Techstream (or by disconnecting the cable from the negative (-) auxiliary battery terminal), permanent DTCs can be cleared when the universal trip is performed and then the system is determined to be normal for the relevant DTCs. The driving pattern to obtain a normal judgment is described under the "Confirmation Driving Pattern" for the respective DTC.
2. To clear permanent DTCs, all of the following conditions must be are met:
  - There is a history that universal trip driving was performed.
  - The vehicle has been judged as normal for 2 trips. (Normal judgment does not have to be performed in 2 consecutive trips, but normal judgment should occur in the latest trip.)
  - No malfunctions are detected.
1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Plug-in Control / Trouble Codes.
  Powertrain > Plug-in Control > Trouble Codes
  
  HINT:
  
  If "YES" is displayed for the value of "PERMANENT" at the top right of the Techstream screen, permanent DTCs are stored.
5. Select the "Generic" tab.
6. Check if permanent DTCs are stored.
  HINT:
  
  If permanent DTCs are not output, it is not necessary to continue this procedure.
7. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  Powertrain > Plug-in Control > Clear DTCs
  
  NOTE:
  Do not clear the DTCs or disconnect the cable from the auxiliary battery terminal after performing this step.
8. Perform the universal trip.
  WARNING:
  When performing the driving pattern, obey all speed limits and traffic laws.
  
  HINT:
  
  The universal trip driving pattern and normal judgment procedure can be performed consecutively in the same driving cycle.

  1. Turn the power switch on (READY) and wait for 30 seconds or more.
  2. Drive the vehicle at 40 km/h (25 mph) or more for a total of 5 minutes or more.
    HINT:
    
    It is possible to complete the drive pattern even if the vehicle decelerates to less than 40 km/h (25 mph) during the driving cycle provided that the vehicle is driven at 40 km/h (25 mph) or more for a total of 5 minutes.
  3. Allow 10 minutes or more to elapse from the time the power switch turned on (READY).
9. Turn the power switch off and wait for 2 minutes or more.
10. Perform the normal judgment procedure in the respective confirmation driving pattern of each output DTC.
  HINT:
  
  Do not turn the power switch off by mistake during this step.
