Danger: Always perform the High-Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal Protection Equipment (PPE) and proper procedures must be followed.

The High-Voltage Disabling procedure will perform the following tasks:

•	Identify how to disable high voltage.

•	Identify how to test for the presence of high voltage.

•	Identify conditions under which high voltage is always present and personal protection equipment (PPE) and proper procedures must be followed.

Before working on any high-voltage system, be sure to wear the following Personal Protection Equipment:

•	Safety goggles with appropriate side shields when within 15 metres (50 feet) of the vehicle, either indoors or outdoors.

•	Certified and up-to-date Class "0" Insulation gloves rated at 1000 V with leather protectors.

-	Visually and functionally inspect the gloves before use.

-	Wear the Insulation gloves with leather protectors at all times when working with the high-voltage battery assembly, whether the system is energised or not.

Failure to follow the procedures exactly as written may result in serious injury or death.

Verify DTC P0D2A is not set.

⇒	If DTC is set, disable the high voltage at the T18 battery charger. Refer to High Voltage Disabling . Replace the T18 battery charger.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
