Check Condition C
Battery Management Unit (BMU) power supply voltage is more than 7.578 volts.
Shutdown sequense: ON
Judgment Criterion A-1
When the transistor switch of the failed battery cell number is on, the voltage of the failed battery cell number changes to 2.09 volts or less.
When the transistor switch of the failed battery cell number is off, the voltage of the failed battery cell number changes to 4.26 volts or more.
When the transistor switch before the failed battery cell number is on, the voltage before the failed battery cell number changes to 4.26 volts or more.
When the transistor switch before the failed battery cell number is off, the voltage before the failed battery cell number changes to 2.09 volts or less.
Judgment Criterion A-2
When the transistor switch of the failed battery cell number is on, the voltage of the failed battery cell number changes to 4.26 volts or more.
When the transistor switch of the failed battery cell number is off, the voltage of the failed battery cell number changes to 2.09 volts or less.
When the transistor switch before the failed battery cell number is on, the voltage before the failed battery cell number changes to 2.09 volts or less.
When the transistor switch before the failed battery cell number is off, the voltage before the failed battery cell number changes to 4.26 volts or more.
Judgment Criterion B
The cell voltage is between 2.09 volts and 4.26 volts for 1.14 seconds or more.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
The trouble can be an intermittent malfunction (Refer to General Information - How to Use Troubleshooting/Inspection Service Points, How to Cope with Intermittent Malfunctions HOW TO COPE WITH INTERMITTENT MALFUNCTIONS).
3.Check the looseness or foreign material attached on the bus bar
