• Read the Freeze Frame Data of DTC P3000-4B.

  Powertrain > Hybrid Control > DTC(P3000-4B) > Freeze Frame Data 

  Tester Display
  VH-Voltage after Boosting
  Hybrid/EV Battery Block 1 Voltage
  Hybrid/EV Battery Block 2 Voltage
  Hybrid/EV Battery Block 3 Voltage
  Hybrid/EV Battery Block 4 Voltage
  Hybrid/EV Battery Block 5 Voltage
  Hybrid/EV Battery Block 6 Voltage
  Hybrid/EV Battery Block 7 Voltage
  Hybrid/EV Battery Block 8 Voltage
  Hybrid/EV Battery Block 9 Voltage
  Hybrid/EV Battery Block 10 Voltage

  NOTE:

  Although Freeze Frame Data is recorded before and after a DTC is stored, for this step it is only necessary to read the Freeze Frame Data recorded before "0s" (when the DTC was stored).

See step  5

Pre-procedure1

• According to the display on the GTS, read the Data List and check that the value of each "Hybrid/EV Battery Temperature 1 to 6" is 40°C (104°F) or less.

  HINT: 

  If the value of any of "Hybrid/EV Battery Temperature 1 to 6" is more than 40°C (104°F), turn the ignition switch off and wait until the values to decrease to 40°C (104°F) or less before continuing this procedure.
