HV Battery (RWD/AWD) (Remove and Replace)
Correction Code 16010102 (RWD), 16010202 (AWD)
Warning
Only technicians who have been
trained in High Voltage Awareness and have completed all required certification
courses (if applicable) are permitted to perform this procedure. Proper personal
protective equipment (PPE) and insulating HV gloves with a minimum rating of
class 0 (1000V) must be worn any time a high voltage cable is handled. Refer to
Tech Note TN-15-92-003, "High Voltage Awareness Care Points"
for additional safety information.
Warning
If the vehicle has air
suspension, activate "Jack" mode on the touchscreen before raising and
supporting the vehicle.
Warning
Before starting this procedure, make sure that all bolts that attach
the battery to the vehicle are installed on the vehicle. Failure to check for missing
bolts might result in the battery pack to become loose unexpectedly, and might injure a
technician.
Note
Use a cordless electric drill with a
3/8 in drive adapter and an 3/8 in drive air ratchet wrench to perform this procedure.
Do not use an impact wrench to remove battery fasteners.
Note
This procedure is intended to be performed by 2 technicians.
Special tools required for this procedure:

Discharge
WARNING: To conform with local laws, High Voltage Lithium Batteries must be discharged before packing for shipment. Additionally, HV batteries must be discharged before being put into storage. HV batteries to be shipped must have a State of Charge (SoC) of less than 30% or 50%, depending on the region. If the method of shipment is unknown or uncertain, or the battery is to be stored, it is recommended to discharge the HV battery to less than 30%.
WARNING: Do not ship or store an HV battery that has a loss of high voltage isolation. Verify HV battery isolation before packing for shipment or storage. Use the HV Battery Communication Tool, described in Toolbox article #41977 or Customer Document CD-21-16-003, to determine if the HV battery parameters are within safe limits for shipment or storage. |
Note
If possible, perform the discharge procedure before HV battery removal. This method requires less time and user interaction than to use the Battery Discharge Tool after the battery has been removed. The Battery Discharge Tool can only be used by certified technicians.
Note
The steps of the discharge procedure are mostly touch time, and can be performed by the Service Advisors/Front of House team as well as Service Technicians.
-
Identify the vehicle SOC.
- If the SOC is less than the specified values, proceed with removal. See Removal.
- If the SOC is greater than the specified values, lower all of the vehicle windows and turn on the climate control system to maximum defrost. This setting will discharge the battery by approximately 10% SOC every hour.
- Move the vehicle to a location where it can safely continue to discharge the battery unattended.
- Identify the vehicle SOC every half-hour.
- When the SOC is below 50% for surface transport, or below 30% for air transport, turn off the climate control system, raise the windows, and then move the vehicle to the service bay.
