See step  2

Pre-procedure1

• Clear DTCs.
• Enter the following menus: Powertrain / Hybrid Control / Data List / Hybrid/EV Battery SOC.

  Powertrain > Hybrid Control > Data List 

  Tester Display
  Hybrid/EV Battery SOC

• According to the display on the GTS, read the Data List and confirm that the SOC of the HV battery is less than 70%.

  HINT: 

  If the SOC of the HV battery is 70% or more, drive the vehicle in EV mode to discharge the HV battery until the SOC becomes less than 70%.

• Turn the Charge Now on.

  HINT: 

  • If no charge schedule has been registered, the above step is not necessary.
  • Setting Charge Now to ON:

    - Using the steering pad switches, select "Charge Now" on the Charge Schedule screen of the multi-information display.

• Plug-in charge the vehicle using the electric vehicle charger cable assembly that was provided with the vehicle.
• Turn the power switch on (IG).
• Enter the following menus: Health Check.

• Check DTCs.

CAUSE ANALYSIS (ENVIRONMENT RELATED CAUSE) 

1. Analyze the cause according to the following table.
   ENVIRONMENT RELATED CAUSE
   
   

   Possible Cause	Action to be Taken
   Short to ground in PISW circuit of charging station	1) Check charging station 2) Charge with the electric vehicle charger cable assembly provided with the vehicle
   Short to ground in PISW circuit of electric vehicle charger cable assembly other than one provided with vehicle	1) Inspect the charging cable that the customer used 2) Charge with the charging cable provided with the vehicle

2. Take appropriate action in accordance with the result of the cause analysis.

Result: 

B 

See step  3

HINT: 

Perform the inspection with the charging cable (electric vehicle charger cable assembly) disconnected from the vehicle and external outlet.

1. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition	Result
   3(PISW) - 5(GND)	Latch release button (PISW) is pressed	430 to 530 Ω	Ω
   3(PISW) - 5(GND)	Latch release button (PISW) is not pressed	135 to 165 Ω	Ω

REPLACE CHARGING CABLE (ELECTRIC VEHICLE CHARGER CABLE ASSEMBLY) 

Result: 

OK 

See step  4

HINT: 

Perform the inspection with the charging cable (electric vehicle charger cable assembly) disconnected from the charging inlet.

Pre-procedure1

• Check that the service plug grip is not installed.
  NOTE:

  After removing the service plug grip, do not turn the ignition switch to ON (READY), unless instructed by the appropriate service information because this may cause a malfunction.

• Disconnect the H124 electric vehicle charger assembly connector.

• Measure the resistance according to the value(s) in the table below.

See step  5

Pre-procedure1

• Disconnect the Hm1 AC charger inlet cable connector.
  NOTE:

  If the Hm1 connector is disconnected with the auxiliary battery connected, P0D56-15 may be detected. Check that the cable is disconnected from the negative (-) auxiliary battery terminal before proceeding work.

• Measure the resistance according to the value(s) in the table below.
