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 condition 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 glasses with appropriate side shields when within 50 feet of the vehicle, either indoors or outdoors.
* Certified and up-to-date Class "0" Insulation gloves rated at 1000V with leather protectors.
- Visually and functionally inspect the gloves before use.
- Wear the Insulation gloves at all times when working with the high voltage battery assembly, whether the system is energized or
not.
Failure to follow the procedures exactly as written may result in serious injury or death.
1. Ignition OFF, disable the high voltage at the drive motor generator battery. Refer to High Voltage Disabling ().

The voltage of any two consecutive batteries multiplied by 20 is 70 V greater than or less than the total pack voltage for 16 seconds.
DTC P0B9B
The voltage of battery 20 multiplied by 20 is 70 V greater than or less than the total pack voltage for 16 seconds. DTC P0B9B only requires one
voltage failure because battery 20 is the last battery.

P0B8D, P0B92, P0B97, and P0B9C are type B DTCs.
* The drive motor generator battery control module commands the battery vent fan to high speed.
* If more than 4 of these DTCs are set, the drive motor generator battery sends a message to the hybrid powertrain control module to reduce the
power use limit to 50 percent.
