  3. CHECK ENGINE START 
    1. Turn the power switch on (READY).
    2. Check if the engine starts.
      NOTE:

      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.

      HINT:

    3. Turn the power switch off.

    B 

    LEAVE VEHICLE WITH SHIFT LEVER IN P, AND CHARGE HV BATTERY BY IDLING UNTIL IDLING STOPS 

    A 

    See step  4

  4. CHECK CRANKSHAFT PULLEY REVOLUTION (P POSITION) 
    1. With the shift lever in P and lift up the vehicle.
    2. Turn the crankshaft pulley using hand tools to check if the crankshaft can rotate smoothly.
      WARNING:

      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.

      NOTE:

      Engine compression causes resistance when turning the crankshaft pulley. Check if the crankshaft rotates smoothly (or if it is locked) by manually applying sufficient torque to turn the crankshaft pulley. The torque required to turn the crankshaft pulley should be the same as for a known good vehicle of the same type.

      Result

      Result Proceed to
      The crankshaft rotates smoothly. A
      The crankshaft does not rotate smoothly. B
    3. Lower the vehicle.

  5. CHECK HV BATTERY 
    1. Turn the power switch off.
    2. Wait 10 minutes or more.
    3. Connect the Techstream to the DLC3.
    4. Turn the power switch on (IG).
    5. Enter the following menus: Powertrain / Hybrid Control / Data List / Battery Block Vol -V01 to 17.
    6. Read the Data List.

      Result

      Result Proceed to
      One or more battery block voltages are below 12.0 V. A
