Inspection Procedure

HINT: 

• Repeating this inspection for symptom confirmation may cause the SOC to drop, preventing the system from entering the READY-on state. In this case, use the THS charger to charge the HV battery.
• Cranking the engine once causes the SOC to drop approximately 1%.
• Charging the HV battery once (10 minutes) using the THS charger restores the SOC approximately 2%.
• Charging the HV battery using the THS charger takes approximately 10 minutes when the HV battery temperature is 25°C or approximately 30 minutes when the HV battery temperature is 0°C.
• The THS charger is a supplemental charging device that charges the HV battery enough to enable the engine to start (the vehicle can enter the READY-on state).
• Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
