order the battery pack.
TAC will then provide guidance if internal components should be replaced or if the
complete pack should be replaced.

Service Center (BSC) Label Master 1-844-931-4966 to order the Drive Motor Battery

Use SI procedures to determine whether a pack is needed. GM TAC can provide guidance to
repair or replace.
Warranty claims will be audited to ensure the minimum number of parts were replaced to
repair the vehicle.
Please note the information required at the time of ordering is contained under Parts

Batteries are on exchange, and new or refurbished material will be provided at or above the
capacity of the battery being removed.

Material will arrive within 72 hours of ordering. For any delays or backorders, please contact
the GM Battery Service Center by calling 1-844-931-4966 for the status of your order.
Important: United States: To ship the hybrid battery, the Service Department/Technician will need to obtain
the EL-53076 for removing the Coolant from the battery from the GM Special Tool Loan
Program (if tool was not already shipped to service) Refer to Service Bulletin #16-NA-158: U.S.
Dealer Special Tool Loan Program for additional information. Obtain the battery pack tracking number from the
GM BSC or TAC before ordering the EL-51865 Battery Pack Support Fixture as there is only a 5-day rental period
before the tool needs to be returned.

Parts Retention and Returns (United States Service Agents ONLY)
All exchanged Li-Ion drive motor batteries are required to be returned for possible refurbishment.
If the batteries are not returned within 30 days, the dealer will be charged back the value of a replacement
battery pack.
These charges are substantial.
Important: Li-Ion batteries are hazardous material. GM requires that at least one person be hazmat certi ed per
servicing dealer. Additional resources for hazardous material shipping can be found as part of appendix G in the
latest version of Service Bulletin # 99-00-89-019. A compromised (damaged) battery is hazardous waste and must
be discharged according to SI procedures for damaged packs. All hazardous materials and hazardous waste must
be shipped in accordance with all local, state, and federal laws.

Correction:
Please have a certified High Voltage Technician follow the diagnostic procedures below
while contacting GM TAC
1. If DTCs are present and procedure gives direction to remove internal components; stop,
capture GDS2 Session Log stored data, and test drive vehicle with GDS and MDI, and capture
a snapshot of the BECM data when condition occurs. See Latest version of PIP4902 for
correct session logs data collection and procedure for emailing. TAC will request that you email the Session Logs to them. Do not clear codes prior to capturing data and calling TAC.
U.S. dealers: PIP5632E can also be used to attach the session logs to the TAC case through
the DCM portal.
2. If DTCs are not present, refer to “Symptoms - Hybrid Controls " in SI.

3. If any diagnostic procedure gives direction to remove internal components, stop and call
TAC, internal components should not be removed at this time.
4. Upon review of the diagnosis, TAC will establish a case reference number with approval for
the dealer to order Lithium-Ion material directly from the GM Battery Service Center
(BSC). Canadian dealers the battery will be ordered for you
5. After verifying that the high voltage systems are disabled, remove battery assembly per
SI procedures.
6. Prior to contacting TAC, check with your parts personnel for the parts department hours of
operation (including Saturdays if open) and the name of the parts contact that will be
handling the battery pack. This information along with the battery identification number
(BIN) and the 4-digit battery capacity number will need to be supplied to the BSC prior to
ordering the battery.
6.1 The battery pack capacity is in the BECM under hybrid/electric Vehicle battery pack
Capacity data list. We are looking for the Total Energy storage Capacity in AH
6.2 The battery has a battery identification tag that is located on the right front of the
battery, image 1, front of vehicle image 2 . Locate the tag and record the 16-digit battery
identification number (BIN). also the QR code can be scanned to gather information, Image 3

Note: The exchange unit will be shipped without coolant. Follow SI procedure for proper
coolant and fill procedures. Low coolant or wrong coolant could result in internal battery
damage
After the Battery has been removed from the vehicle (see service manual procedure), and
before placement into the Wooden Shipping Crate, prepare the battery for return by
performing the following:
1) Install Coolant plugs (2) in coolant lines. Coolant plugs can be removed from the new
service battery assembly and installed in the returned battery. Note: As part of the battery
removal process, all coolant should be drained from the drive motor battery using the EL53076.
In order to properly prepare the used battery for shipping and to ensure safe shipment, all of
the above steps must be followed.
Danger: The high voltage (HV) battery must be protected when outside of the vehicle. This is
why the battery must be immediately placed in the original shipping container (Wooden
Shipping Crate).

Storage Guidelines:
1) Store the Drive Motor Battery flat.
2) Store the Drive Motor Battery in an environmentally protected area.
3) Maintain the Drive Motor Battery at room temperature.
4) Protect the Drive Motor Battery from exposure to liquids.
5) Protect the Drive Motor Battery from physical damage.
6) Store the Drive Motor Battery in a limited-access area.
