danger

When servicing the high voltage components, be sure to remove the service plug in order to shut off the high voltage (Refer to PRECAUTIONS ON HOW TO USE THE HIGH-VOLTAGE VEHICLE).
When servicing the high voltage components, be sure to wear an insulating protective equipment to measure the high voltage (Refer to PRECAUTIONS ON HOW TO USE THE HIGH-VOLTAGE VEHICLE).

1.Insulation resistance check of generator

Check the insulation resistance of the generator (Refer to CHECK ON INSULATION RESISTANCE OF GENERATOR

Is the check result normal?

Replace the generator (Refer to ( GENERATOR REMOVAL AND INSTALLATION

2.Insulation resistance check of power drive unit

Check the insulation resistance of the power drive unit (Refer to CHECK ON INSULATION RESISTANCE OF POWER DRIVE UNIT

Is the check result normal?

Replace the power drive unit (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATION

3.Check whether the DTC is set again.

Is the DTC set?

Perform the "Inspection procedures when BMU P0AA6-00: Insulation Resistance Drop Detection Diagnosis is set." again (Refer to DIAGNOSIS CHART FOR DTC No. P0AA6-00

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
