DTC P3000-389: HV Battery Malfunction: Procedure

CHECK DTC OUTPUT (HV)
1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.
4. Check if DTCs are output.
  Result
  
  DTCs other than P3000-388 or P3000-389 are output.
  
  HINT:
  
  If the HV battery voltage has dropped due to a malfunction in other components (inverter with converter assembly, hybrid vehicle transmission assembly), recharge the HV battery and then repair the malfunctioning part.
YES → GO TO DTC CHART

NO: Go to next step
CHECK DTC OUTPUT (ENGINE CONTROL SYSTEM)
1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Select the following menu items: Powertrain / Engine and ECT / Trouble Codes.
4. Check if DTCs are output.
  Result
  
  Engine control system DTCs are output.
YES → GO TO DTC CHART

NO: Go to next step
CHECK ENGINE START
1. Turn the power switch on (READY).
2. Check if the engine starts.
  HINT:
  
  Depressing the accelerator pedal with the shift lever in the P position will cause the engine to start.
  
  OK
  
  The engine starts.
  
  WARNING:
  Do not turn the power switch on (READY) repeatedly after duplicating the problem symptom indicated by DTC P3000-389 and clearing the DTCs. This may cause another problem to occur.
YES → LEAVE VEHICLE IN P POSITION, AND CHARGE HV BATTERY IN IDLE STATUS UNTIL IDLING STOPS

NO: Go to next step
CHECK CRANKSHAFT PULLEY REVOLUTION (P POSITION)
1. Turn the power switch off, move the shift lever to the P position, and lift up the vehicle.
2. Turn the crankshaft pulley using hand tools to check if the crankshaft pulley can rotate.
  NOTE:
  Do not turn the power switch on (READY) while performing this inspection. Be sure to turn the power switch off before performing this inspection, to prevent the engine from starting.
  
  OK
  
  The crankshaft pulley rotates.
NG → See step 6

OK: Go to next step
CHECK HV BATTERY ASSEMBLY
1. Turn the power switch off and wait 10 minutes or more.
2. Connect the Techstream to the DLC3.
3. Turn the power switch on (IG).
4. Select the following menu items: Powertrain / Hybrid Control / Data List / Battery Block Vol-V01 to V20, Power Resource VB.
5. Read the data list.
  Result
  
  All battery block voltages are 12.0 V or more.
YES → See step 9

NO → See step 10
CHECK CRANKSHAFT PULLEY REVOLUTION (N POSITION)
1. Turn the power switch off, move the shift lever to the N position, and lift up the vehicle.
2. Turn the crankshaft pulley using hand tools to check if the crankshaft pulley can rotate.
  NOTE:
  Do not turn the power switch on (READY) while performing this inspection. Be sure to turn the power switch off before performing this inspection, to prevent the engine from starting.
  
  OK
  
  The crankshaft pulley rotates.
OK → See step 8

NG: Go to next step
