HINT: 

• *: Use the Techstream
• Use the following procedure to troubleshoot the plug-in charge control system.

1. VEHICLE BROUGHT TO WORKSHOP 

   NEXT: Go to next step 

2. CUSTOMER PROBLEM ANALYSIS 

   NEXT: Go to next step 

3. CONNECT TECHSTREAM TO THE DLC3* 

   HINT: 

   If the display on the tester indicates a communication fault, inspect the DLC3.

   NEXT: Go to next step 

4. CHECK DTC AND SAVE FREEZE FRAME DATA*. Refer to  DTC CHECK / CLEAR [08/2014 - ]  

   HINT: 

   • If any of the CAN communication system DTCs is output, troubleshoot and repair the CAN communication system first. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [08/2014 - ] .
   • If the Freeze Frame Data item "On-Board Charger Input Voltage" shows 270 V or more, there is a possibility that the charging voltage was higher than standard voltage, causing a DTC to be output. When performing a reproduction test, plug-in charge the vehicle at the standard voltage (100 to 240 V), then check for DTCs.
