   Add fuel until the low fuel level warning light turns off.

3. Turn the ignition switch off.

Result: 

B 

REFUEL VEHICLE 

Result: 

A 

See step  4

1. Read the freeze frame data item "Shift Position" of DTC P3000-00.

   Powertrain > HV Battery > Trouble Codes 

   Powertrain > HV Battery 

   Tester Display
   Shift Position

   NOTE:

   • When the freeze frame data "Shift Position" was N, DTC P3000-00 may be stored due to the vehicle was left with the shift lever in N and the HV battery could not be charged.
   • If DTC "P3000-00" only is output, charge the HV battery without replacing the HV battery if necessary.
2. Turn the ignition switch off.

See step  5

1. Turn the ignition switch to ON (READY).
2. Check if the engine starts.

   HINT: 

   • Depressing the accelerator pedal with the shift lever in P will cause the engine to start.
   • Turning the ignition switch to ON (READY) and off repeatedly while the SOC is low may cause the SOC to drop further, resulting in DTC P3000-16 being stored. Charge the HV battery using the THS charger as necessary.
   • 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%.

   Result

   Result	Proceed to
   The engine starts.	A
   The engine does not start.	B

3. If the engine does not start, turn the ignition switch off.

Result: 

A 

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

Result: 

B 

See step  6

1. Clear the DTCs and freeze frame data.

   Powertrain > HV Battery > Clear DTCs 

2. Perform a road test.
